  • Set up USB for Virtualbox

    - by kst
    I'm using Ubuntu Maverick and Virtual Box 3+ and I installed Window 7 Ultimate Editon. The problem is that it doesn't detect USB drives on Window 7 but USB peripherals (mouse + keybord) are working. I followed this instruction, but I can't find the user group vboxusers. How can I continue? I would also like to upgrade to the latest version without any risk (without losing my virtual hard disk drive).

  • How can a Virtualbox host connect to a guest VM when host wireless is disabled / host Ethernet cable is unplugged?

    - by uloBasEI
    I have a Virtualbox VM running on a computer connected to Internet via an Ethernet cable. The guest has a network adapter attached to a NAT. 2 ports (22 and 80) are forwarded so that the host can access them respectively on localhost:2222 and localhost:8080. When the Ethernet cable is plugged, both machine (host and guest) can access Internet and the host can access the SSH server/Webserver which ports are forwarded. When I unplug the Ethernet cable from the host, the host can not access the SSH server/Webserver of the guest anymore. Same situation with a Laptop connected to Internet via wireless when I disable the wireless adapter or set a wrong WPA key. My question is: is there a workaround for the host to access the guest services even if its Ethernet cable is unplugged / wireless is not available?

  • VirtualBox VERR_ACCESS_DENIED for Ubuntu 11.10

    - by kaspnord
    I installed Ubuntu 11.10 on VBox. The VBox settings I use have been tried and proven for countless other installs I have done in the past. Those are still up and running. On my latest install of Ubuntu 11.10 on Vbox, things were working well in the initially - I installed Guest Additions and everything was fine. All of a sudden (I was just moving my mouse), I get an accessed denied error that freezes my entire Ubuntu environment. I close the virtual machine and restart it, but now I keep getting this error message: Any help would be greatly appreciated.

  • Is this an apt-get issue or network issue?

    - by zharvey
    I just installed my first Ubuntu server (12.04) instance and immediately am noticing a few things: Running apt-get install or update fails (see below) Running ifconfig produces peculiar IP addresses starting with 10.x.x.x and my router does not see the server at all in its "Attached Devices" page (its a consumer grade Netgear) When I run apt-get I get 50+ of the following errors: Failed to fetch <some-http-url. Temporary failure resolving <blah.ubuntu.com I read up on this error for 12.04, and found some similar posts on this forum and on serverfault that recommended going into /etc/resolv.conf and adding an entry: nameserver 8.8.8.8 To my surprise, I found that /etc/resolve.conf was a symlink pointing to somewhere else and I had to delete it first, then create a new one with the entry indicated above. I restarted the server and tried running apt-get again: same results. How do I start diagnosing the problem (I'm a relatively new Linux/Ubuntu user)? Additional details that may help: This is actually a virtual machine running as a VirtualBox guest OS The physical host that is running this VM is my laptop which has a wireless connection; I'm wondering if (somehow) the laptop is getting the network wirelessly, but perhaps either the VBox VM and/or the Ubuntu server OS isn't configured for wireless and so nothing is "getting through"? Thanks in advance for any pointers! Edit: Here is a snapshot of my VM's Network settings (only Adapter 1 has any information populating its fields, so I assume my VM has only 1 adapter): Here is the output when I run ifconfig from the terminal: And here is the output when I run route from the terminal: Running ping google.com:

  • Ubuntu Server 12.04 as a router. Problem with DNS

    - by Lorenzo
    I have a virtualbox lab made up of 4 Windows 2008 R2 servers (DC/DNS,SQL,SHAREPOINT, EXCHANGE) that are configured with static ip addresses with NIC's attached to Internal network. Everything works. I had the requirement to execute some tests that also access external services available on the internet. To keep things clean and similar to the production environment I have installed another VM, with Ubuntu Server 12.04 64 bit and configured (I hope) to work as a router like described on this post. This VM has two network interfaces: first is Bridged with the host and is used as a WAN connection and the other one attached in the Internal Network with its own static IP address on the internal network subnet. But actually the Windows servers does not connect to the internet while the unix one connects. I did a route command. this is the result: Kernel IP Routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.69.121.1 0.0.0.0 UG 100 0 0 eth0 10.69.121.0 * 255.255.255.0 U 0 0 0 eth0 192.168.83.0 * 255.255.255.0 U 0 0 0 eth1 Can somebody help me with this configuration? :) Thanks! Addendum: I forgot to mention that one of the windows server hosts a DNS service for which I should maybe configure a forwarding server but I do not exactly know which server to forward on... :(

  • How To Run XP Mode in VirtualBox on Windows 7 (sort of)

    - by Matthew Guay
    A few weeks ago we showed you how to run XP Mode on a Windows 7 computer without Hardware Virtualization using VMware. Some of you have been asking if it can be done in Virtual Box as well. The answer is “Yes!” and here we’ll show you how. Editor Update: Apparently there isn’t a way to activate XP Mode through VirtualBox using this method. You will however, be able to run it for 30 days. We have a new updated article on how to Install XP Mode with VirtualBox Using the VMLite Plugin.   Earlier we showed you how to run XP mode on windows 7 machines without hardware virtualization capability. Since then, a lot of you have been asking to a write up a tutorial about doing the same thing using VirtualBox.  This makes it another great way to run XP Mode if your computer does not have hardware virtualization.  Here we’ll see how to import the XP Mode from Windows 7 Professional, Enterprise, or Ultimate into VirtualBox so you can run XP in it for free. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. In our tests we were able to get it to run on Home Premium as well, but you’ll be breaking Windows 7 licensing agreements. Getting Started First, download and install XP Mode (link below).  There is no need to download Virtual PC if your computer cannot run it, so just download the XP Mode from the link on the left. Install XP mode; just follow the default prompts as usual. Now, download and install VirtualBox 3.1.2 or higher(link below).  Install as normal, and simply follow the default prompts. VirtualBox may notify you that your network connection will be reset during the installation.  Press Yes to continue. During the install, you may see several popups asking you if you wish to install device drivers for USB and Network interfaces.  Simply click install, as these are needed for VirtualBox to run correctly. Setup only took a couple minutes, and doesn’t require a reboot. Setup XP Mode in VirtualBox: First we need to copy the default XP Mode so VirtualBox will not affect the original copy.  Browse to C:\Program Files\Windows XP Mode, and copy the file “Windows XP Mode base.vhd”.  Paste it in another folder of your choice, such as your Documents folder. Once you’ve copied the file, right-click on it and click Properties. Uncheck the “Read-only” box in this dialog, and then click Ok. Now, in VirtualBox, click New to create a new virtual machine. Enter the name of your virtual machine, and make sure the operating system selected is Windows XP. Choose how much memory you want to allow the virtual machine to use.  VirtualBox’ default is 192 Mb ram, but for better performance you can select 256 or 512Mb. Now, select the hard drive for the virtual machine.  Select “Use existing hard disk”, then click the folder button to choose the XP Mode virtual drive. In this window, click Add, and then browse to find the copy of XP Mode you previously made. Make sure the correct virtual drive is selected, then press Select. After selecting the VHD your screen should look like the following then click Next. Verify the settings you made are correct. If not, you can go back and make any changes. When everything looks correct click Finish. Setup XP Mode Now, in VirtualBox, click start to run XP Mode. The Windows XP in this virtual drive is not fully setup yet, so you will have to go through the setup process.   If you didn’t uncheck the “Read-only” box in the VHD properties before, you may see the following error.  If you see it, go back and check the file to makes sure it is not read-only. When you click in the virtual machine, it will capture your mouse by default.  Simply press the right Ctrl key to release your mouse so you can go back to using Windows 7.  This will only be the case during the setup process; after the Guest Additions are installed, the mouse will seamlessly move between operating systems. Now, accept the license agreement in XP.   Choose your correct locale and keyboard settings. Enter a name for your virtual XP, and an administrative password. Check the date, time, and time zone settings, and adjust them if they are incorrect.  The time and date are usually correct, but the time zone often has to be corrected. XP will now automatically finish setting up your virtual machine, and then will automatically reboot. After rebooting, select your automatic update settings. You may see a prompt to check for drivers; simply press cancel, as all the drivers we need will be installed later with the Guest Additions. Your last settings will be finalized, and finally you will see your XP desktop in VirtualBox. Please note that XP Mode may not remain activated after importing it into VirtualBox. When you activate it, use the key that is located at C:\Program Files\Windows XP Mode\key.txt.  Note: During our tests we weren’t able to get the activation to go through. We are looking into the issue and will have a revised article showing the correct way to get XP Mode in VirutalBox working correctly soon.    Now we have one final thing to install – the VirtualBox Guest Additions.  In the VirtualBox window, click “Devices” and then select “Install Guest Additions”. This should automatically launch in XP; if it doesn’t, click Start, then My Computer, and finally double-click on the CD drive which should say VirtualBox Guest Additions. Simply install with the normal presets. You can select to install an experimental 3D graphics driver if you wish to try to run games in XP in VirtualBox; however, do note that this is not fully supported and is currently a test feature. You may see a prompt informing you that the drivers have not passed Logo testing; simply press “Continue Anyway” to proceed with the installation.   When installation has completed, you will be required to reboot your virtual machine. Now, you can move your mouse directly from Windows XP to Windows 7 without pressing Ctrl. Integrating with Windows 7 Once your virtual machine is rebooted, you can integrate it with your Windows 7 desktop.  In the VirtualBox window, click Machine and then select “Seamless Mode”.   In Seamless mode you’ll have the XP Start menu and taskbar sit on top of your Windows 7 Start and Taskbar. Here we see XP running on Virtual Box in Seamless Mode. We have the old XP WordPad sitting next to the new Windows 7 version of WordPad. Another view of everything running seamlessly together on the same Windows 7 desktop. Hover the pointer over the XP taskbar to pull up the Virtual Box menu items. You can exit out of Seamless Mode from the VirtualBox menu or using “Ctrl+L”. Then you go back to having it run separately on your desktop again. Conclusion Running XP Mode in a Virtual Machine is a great way to experience the feature on computers without Hardware Virtualization capabilities. If you prefer VMware Player, then you’ll want to check out our articles on how to run XP Mode on Windows 7 machines without Hardware Virtualization, and how to create an XP Mode for Windows 7 Home Premium and Vista.

  • Setting up a network between a host and guest virtual machine

    - by anonymous
    (I'm running ubuntu server 12.04 on virtual box) I'm trying to transfer a file (scp) from my laptop to one of the directories of a virtual machine. I tried sharing folders, but that failed. I'm a bit of a networking newbie. I've looked at like 20-30 pages. Here's one: http://www.howtoforge.com/moving-files-between-linux-systems-with-scp I followed those steps exactly. My problem is that when I try using scp, it just hangs. I'm also not sure which network interface to configure (eth0, eth1?) in the guest OS. Another (significant?) detail is that the inet address of eth0 is 10.0.2.15 instead of something like 192.168.x.y. I've enabled the bridge adapter and the host-only adapter. Both the laptop and guest VM have openssh-server installed. I'm not sure what to do at this point. Is there a better place to ask about this?

  • Website hosted on my virtualbox web server not displaying images or applying css when viewed through phone

    - by WebweaverD
    I would really appreciate it if someone could help me. Please let me know if you need more info in the comments. My Set Up I have a windows 7 pc. On it I run a virtual box VM with a ubuntu 12 guest os and LAMP setup. I share files between the two machines using samba from linux to windows and using windows file sharing (Workgroup) the other way round. The vm is set up with a bridged network adapter and can happily serve web pages to my host machine. I use DHCP reservations on my home wireless router/modem to reserve an ip for the vm and give it a sitename.dev in my windows host file so I can access it at sitename.dev through the browser. The Problem So far so good but I have a dev project which needs a lot of mobile template development, now obviously I can use a browser plugin to simulate a mobile device but I would like to be able to see the real thing easily on my phone during development. So ideally I would like a similar setup on my iphone to my windows setup Now I'm not great on networking and dont have much experience with web server set up. So when I typed the ip of my virtual box into my iphone i wasnt expecting to see anything. I was pleasantly surprised when my site loaded up. The javascript even seems to be running but the images and css are not happening. My Question 1) What is happening here, is it something to do with the bridged set up on the vm network? 2)How do I make the sites load properly through my phone Notes I've also tried another phone. The same sites viewed on live servers work fine.

  • What's In Storage?

    - by [email protected]
    Oracle Flies South for Storage Networking Event Storage Networking World (now simply called SNW) is the place you'll find the most-comprehensive education on storage, infrastructure, and the datacenter in the spring of 2010. It's also the place where you'll see Oracle. During the April 12-15 event in Orlando, Florida, the industry's premiere presentations on storage trends and best practices are combined with hands-on labs covering storage management and IP storage. You'll also have the opportunity to learn about Oracle's Sun storage solutions, from Flash and open storage to enterprise disk and tape. Plus, if you stop by booth 207 in the expo hall, you might walk away with a bookish prize: an Amazon Kindle, courtesy of Oracle. Proving, once again, that education can be quite rewarding.

  • Event system architecture for networking when performance is concerned

    - by Vandell
    How should I design a system for an action game (think in Golden Axe) where events can happen remotely? I'm using TCP for this because the client is in flash. There's so many options, I can make a binary protocol (I don't like this idea, I found it to be too hard to mantain) but I was also thinking that passing jsons through clients and server can be slow (Is that a exaggerated concern?). What about the internal architecture for the server? And for the client? I'm really lost, If it's a question that is too big, please indicate me some material so I can formulate a better question next time.

  • UBUNTU 12.04 Networking

    - by Fr. Lawrence winslow
    I have installed UBUNTU 12.04 on my Athlon 64-bit Desktop (2GB Memory) in a dual-boot with Win XP. The machine is hardwired to my D-Link N router which uses a DSL Modem to access the Internet. My Home Network was established in the router via the XP machine. When I boot UBUNTU I am able to access the Internet via this set-up but I can neither access the home network nor see the three other laptop computers (wireless access) on the network. These others are running Win Vista, Win 7, and UBUNTU 10.04 (this latter accesses the home network normally). All are visible and accessible when XP is running. I would appreciate thoughts as I am seriously thinking about changing all the computers to UBUNTU but do need to be able to operate the network.

  • Best social networking places for programmers.

    - by Chevex
    I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow and related sites but they are more technical and don't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

  • Networking Programs Suitable For Symbolic Testing

    - by Milen
    Symbolic execution has been successfully used to test programs and automatically generate test cases. I've been working on my master's thesis that allows the testing of arbitrary networked programs (i.e., those communicating via sockets). Now that we have a working symbolic execution engine that has support for sockets, we're looking for real-world pieces of software to test. Our engine has an important restriction (at the moment): it cannot execute multi-threaded programs. So, we're looking for programs that satisfy the criteria outlined below: Written in C Communicates via sockets (TCP / UDP are supported) Does not rely on the filesystem to get the "job" done Runs on Linux Does not use multi-threading Source is available (so that we can compile them to LLVM bytecode) Most programs that would fall under the criteria would probably be implementations of distributed protocols solving a particular problem (e.g., consensus). Any suggestions are greatly appreciated.

  • I/O APIC on Virtualbox

    - by RidDeBakTiYar
    I'm trying to use the PIT to do APIC timer calibration, and I want to use the PIT through I/O APIC instead of PIC. On Bochs I get interrupts from the PIT at the asked frequency from the I/O APIC, while on Virtualbox I can't receive a single interrupt. It must be an I/O APIC configuration problem because as I unmask the first PIC entry, the IRQ fires. However that's not what I want. Can you imagine any possible condition that wouldn't make Virtualbox fire the IRQ? I'm not assuming single I/O APIC configuration (even though Virtualbox has only 1). I'm not assuming identity mappings between ISA IRQs and I/O APIC GSIs (using ACPI MADT table to get I/O APIC base address and Int override). I'm setting the Trigger Mode and Polarity bits correctly (on Virtualbox they are set as '00 - default' which means edge high right?). I'm putting the BSP APIC ID into the Destination field (using Physical destination) and vector 0x20. Being the BSP APIC ID 0 on Virtualbox, it ends up with 0x0000000000000020 written to the IOREDTBL. And, just in case I'm getting the wrong values from the Interrupt Override descriptor, I'm setting this value to all the IOREDTBL entries (I know this is very very bad, and it wont be kept as I understand what's going on). The only thing I didn't check out is Local APIC configuration. Actually I'm not writing any value to the BSP LAPIC. Just reading the APIC ID and using it to boot APs through IPIs. And obviously I'm setting bit 11 in the IA32_APIC_BASE MSR to enable the LAPIC. Any ideas? Thanks in advance.

  • How to configure VirtualBox server for performance at home

    - by BluJai
    I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

  • Connecting to the Internet from FreeBSD on VirtualBox

    - by Alex Farber
    I just installed FreeBSD in the VirtualBox running on Ubuntu host, and need instructions to enable Internet access from FreeBSD. My guess that I need to run /usr/sbin/sysinstall and do something there, but I need exact instructions. Details. Host: Ubuntu 9.10, connected to the Internet through LAN. Sun VirtualBox 3.1.4. FreeBSD 8.0 running in the VirtualBox.

  • Resources for game networking in Java

    - by pudelhund
    I am currently working on a Java multiplayer game. The game itself (single player) already works perfectly fine and so does the chat. The only thing that is really missing is the multiplayer part. Sadly I am absolutely clueless on where to start with that. I roughly know that I will have to work with packages, and I also know many things about streaming etc (chat is already working). Oh and it should - according to this article - be a UDP server. My problem is that I can't find any resources on how to do this. A tutorial (book or website) would be perfect, alternatively a good example of an open source client/server (in Java of course) would be fine as well. If you feel like doing something helpful I'd also really appreciate someone "privately" teaching me via email or some chat program :) Thank you!
