  • How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

    - by sauparna
    I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

  • How do I install a CentOS 5.5 in Xenserver?

    - by deweller
    When I try to install CentOS 5.5 in a new VM, I get an error that the installer is unable to retrieve stage2.img. I have verified the URL and I am able to download this file from a web browser. I suspect it is a networking/routing issue, but I can't figure out what is wrong. This is a new install of XenServer 5.6 on a new server. This server is remote, so I don't have physical access to the box - only ssh access. Can anyone give me some tips on what might be wrong here? Do I need to do something special to get a net install to work? For what its worth, I see the same error trying to install Debian Woody using a similar process. Thanks.

  • "domain crashed" when creating new Xen instance

    - by user47650
    I have downloaded a Xen virtual machine image from the appscale project, and I am trying to start it up. However once I run the command; xm create -c -f xen.conf The instance immediately crashes and provides no console output. however it produces logs that I have posted below. but this is the error; [2011-03-01 12:34:03 xend.XendDomainInfo 3580] WARNING (XendDomainInfo:1178) Domain has crashed: name=appscale-1.4b id=10.

  • How to access programs in one PC using another PC

    - by darkstar13
    Hi, I was recently given an old PC for my remote access at work. The CPU that comes with it has Windows XP installed, 400+ MB of ram, all USB devices disabled. I access my work applications using VPN / Citrix. Basically, it' sooooo slow. Plus it's bulky and it will just occupy space, so I am now hoping to find a way for me to integrate this work PC with my home PC. I tried to put in the hard drive in my home PC CPU, and set the drive as slave. However, when I booted my PC from this hard drive, I am stuck at the screen where windows is prompting me to select how am I going to boot (ex. Safe Mode, Safe mode with command prompt, Last Working Configuration, etc), but whatever option I select, I am still stuck at this option after reboot. I am thinking if maybe I can clone the drive and mount the cloned drive and access the system as a virtual machine. But I don't know if that will work. I would like to know if there's something I can do so I can work at home using my home PC, where I can access my work programs to connect to VPN / Citrix. My home PC's OS is Windows 7 Ultimate x64.

  • VSFTPD does not allow upload with virtual users

    - by Mr. Squig
    I am attempting to setup VSFTPD with virtual users on a server running Ubuntu 12.04. I have configured the server to allow for virtual users to login, but I am having trouble getting it to allow uploads. My vsftpd.conf is as follows: listen=YES anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 anon_upload_enable=YES dirmessage_enable=YES use_localtime=YES xferlog_enable=YES connect_from_port_20=YES chroot_local_user=YES virtual_use_local_privs=YES guest_enable=YES guest_username=virtual user_sub_token=$USER local_root=/var/www/$USER hide_ids=YES secure_chroot_dir=/var/run/vsftpd/empty pam_service_name=vsftpd rsa_cert_file=/etc/ssl/private/vsftpd.pem /etc/pam.d/vsftpd contains: auth required pam_pwdfile.so pwdfile /etc/vsftpd.passwd crypt=hash account required pam_permit.so crypt=hash I have two virtual users set up, one of which has the same name as a local user. They each have a directory in /var/www/ owned by 'virtual'. As I understand it, when a virtual user logs in this way they will appear to the system as the user virtual. Using this configuration user can log on, but cannot upload files. The error given in /var/log/vsftpd.log is: Tue Nov 20 19:49:00 2012 [pid 2] CONNECT: Client "96.233.116.53" Tue Nov 20 19:49:07 2012 [pid 1] [zac] OK LOGIN: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 2] CONNECT: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 1] [zac] OK LOGIN: Client "96.233.116.53" Tue Nov 20 19:49:11 2012 [pid 3] [zac] FAIL CHMOD: Client "96.233.116.53", "/test.ppm 644" I have tried changing the permissions of these directories in all sorts of ways, but nothing seem to work. I have a feeling that it is something simple related to permissions. Any ideas?

  • Benchmarking hosting providers IO with Bonnie

    - by Derek Organ
    Ok, because of a bunch of projects I'm working on I've access to dedicated Servers on a 3 hosting providers. As an experiment and for educational purposes I decided to see if I could benchmark how good the IO is with each. Bit of research lead me to Bonnie++ So I installed it on the server and ran this simple command /usr/sbin/bonnie -d /tmp/foo The 3 machines in different hosting providers are all dedicated machines, one is a VPS, other two are on some cloud platform e.g. VMWare / Xen using some kind of clustered SAN for storage This might be a naive thing to do but here are the results I found.

  • Accessing apache in ubuntu 10 virtualbox guest from ubuntu 10 host

    - by Francis L
    I did the following: installed VirtualBox 3.1.6 OSE in ubuntu 10 desktop. installed ubuntu 10 server on a virtual machine in VirtualBox. select "LAMP server" and "OpenSSH server" options during the ubuntu server installation. leave network "adapter 1" of virtual machine as "NAT". use "VBoxManage" described in manual to setup port forwarding on the host (Protocol: TCP, GuestPort: 80, HostPort: 8080). verify "ExtraDataItem" have been added to "ubuntuServer1.xml" (my virtual machine name) correctly. run command "pgrep apache" in ubuntu server in virtual machine to ensure apache is running. Everything went well. But, when I try to access the apache from the browser on the host with "http://localhost:8080/", it just continue fetching with no response. Now, I'm struck! Please help! Many many thanks in advance!

  • Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

    - by Philip Durbin
    I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above? Here's a bit more detail about my setup: [root@kvm01b ~]# cat /etc/redhat-release CentOS release 6.2 (Final) [root@kvm01b ~]# rpm -q virt-v2v virt-v2v-0.8.3-5.el6.x86_64 See also Bug 605334 – VirtIO driver for windows does not show specific OS: Windows 7, Windows 2003

  • How to monitor CPU usage and performance on a Hyper-V server with several VM's

    - by Bjørn
    Hello, I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system. I have set up three Virtual Machines, all running Windows 2008 32 bit. Build server, running Team City Staging server SQL Server, running SQL Server 2005 I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.) So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

  • What is the difference betweeen "Network install" and "Network Boot" options in virt-manager when installing a new virtual machine

    - by Marwan
    From my understanding of PXE (Preboot Execution Environment), I know that there must be some negotiation first between the booting client and a DHCP server to obtain network parameters (IP address, etc) in order for the client to be able to fetch the boot loader and kernel image from the boot server. In other words, and aside from being a "virtual" machine, we're talking here about a "bare metal" machine, so there must be some "pre boot" mechanism for those negotiations to take place, and this is exactly what PXE is all about. When I think about the "Network install" option, I can't figure out how the new VM would be able to fetch the boot images (bootloader and kernel) without the previously mentioned mechanism. So, here is a short version of the question: When provisioning a new virtul machine, how do you expect the "Network install" option in virt-manager to work behind the scenes? Many thanks.

  • 0x0000007b WinXP in VirtualBox with no Admin access on source drive

    - by Ozzah
    I have a physical drive with an installation of WinXP-32 which I have made a clone of using SysInternals disk2vhd. I have no admin rights on this installation. I have tried to boot this VHD in VirtualBox, however it blue screens on 0x0000007b. I have researched this and apparently the cause is that Windows doesn't like the IDE controller changing. I have tried all the available controllers in VirtualBox, but they all produce the same result. There is a Microsoft KB article which describes a method involving loading a .reg file and extracting some sys files from a CAB. This method apparently works well for many people with this problem, however it will not work for me as I don't have admin rights on the WinXP installation. Is there anything I can do in this case? Is there any way of loading the .reg file outside the OS? or perhaps doing a repair using the WinXP CD? Even though I have no admin rights on the source drive installation of Windows, I do obviously have full access to the file system directly on the drive and also in the VHD itself.

  • Need a VM for running a PHP Sandbox

    - by Phani
    I am working on Web application honeypot. It collects PHP files it receives (as part of an RFI attack) and runs them in order to return the result back to the attacker. The aim is to coax the bad guy into going further into his attack. Based on the answers to my SO question, I am looking at using VMs for running the PHP Sandbox. The honeypot itself consists of Python code and will be running in a Linux environment (preferably Ubuntu-like). These are some of the requirements: The VM should be a light weight as possible. We are going to distribute the code around and many people are going to use the VM along with the Python based honeypot. So, the installation and configuration should not be too difficult. The guest system would also be Linux as we are going to distribute the VM image around. It should be possible for the Python code outside to talk to the guest system. It would be passing on the PHP file to the guest system and will get the output result from it. It should be possible to automate the initial configuration of the VM (such as allocation of RAM etc.) I would like to randomize these settings in order to make the sandbox less 'fingerprintable' I have looked at OpenVZ and KVM so far. Are there any other VMs that I might look at? What do you recommend?

  • KVM virtual machine networking, NAT and bridge together

    I have two running KVM guests on an Ubuntu (Lucid) host. One of them uses the simplest NAT method, and DHCP inside. The other uses the bridge method and static IP inside. Both work fine. Can I mix the networking methods? I'd like to create some set of scripts which used the local 192.168.122.x address, no matter if the guest has or not has an additional bridged LAN interface. Having eth0 and eth1 interfaces inside would be fine. Thanks for your interest.

  • Ubuntu 12.04 KVM running Ubuntu 12.04 with linux-image-virtual crash on boot

    - by D.Mill
    One of my VMs is stuck on "pause" in virsh. If I destroy and restart it, it will go to pause after a bit of time as "running". I can at best enter my username at login if I'm quick but it'll then shutdown. I don't know where to start with this so any help would be great!! I can access the VMs files via guestfish. the kern.log and syslog don't populate new lines. This is the last input I get from kern.log: Dec 13 11:21:08 soft201 kernel: imklog 5.8.6, log source = /proc/kmsg started.

  • "A disk read error occurred" when booting XP disk image in VirtualBox

    - by intuited
    I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

  • BSOD trying to migrate Windows XP from a physical to a virtual machine

    - by pauldoo
    I am attempting to migrate a Windows XP Home installation from a physical machine to a virtual machine. The physical machine has two hard disks; the first is 250GB containing the "C:", the second is 1TB containing "D:". I'd like to create a new virtual machine stored on the D:, which is a copy of the Windows XP Home installation that is currently on the C:. (This will leave the 250GB drive clear for me to install a fresh copy of Windows 7, and still be able to access the old XP installation if necessary.) The first method I tried was to follow the instructions here: http://www.virtualbox.org/wiki/Migrate_Windows I booted up from an Ubuntu Live CD in order to execute the Linux commands whilst the Windows system wasn't running. With this method the virtual machine would always blue screen on startup with a "STOP 0x0000007B" message. The instructions above say to try a "repair install" using the Windows XP disc. Unfortunately for me my XP disc is scratched and will not boot so I was unable to try a repair install. The second method I tried was to use "VMWare Converter Standalone Client". This tool executed without any errors, but again produced a virtual machine that blue screens on startup with the same "STOP" message. Are there any other methods to move the Windows XP installation into a virtual machine? I think next I will try some more manual process to create the cloned virtual machine. I think I will try installing a fresh copy of Windows XP to a virtual machine, then once that is booting OK I will ntfsclone the source C: partition over the top. Perhaps this will fix the booting problems if the issue is related to the MBR or partition table in some way.

    - by okhalid
    Hi, I need to install Fedora 11 in my monitor-less linux box which is running some where in a data center. I will use Fedora 11 as a virtual machine. What I already know/have: 1) How to create LVM partitions and create ext3 filesystem 2) Mount the LVM partition and ISO image 3) Run the partition with Xen as a virtual machine What I need: 1) I need to install Fedora ll file system into an lvm partition (let's say /dev/fedora11) from an ISO image so that I have all the directories /root, /bin, /sys etc etc under /dev/fedora11 Any help would be much appreciated! NOTE: I don't have a monitor for this server, so I need to do it via SSH

  • DHCP reply packets do not make it into KVM instance in OpenStack

    - by Lorin Hochstein
    I'm running a KVM instance inside of OpenStack, and it isn't getting an IP address from the DHCP server. Using tcpdump, I can see the request and reply packets on vnet0 of the compute host: # tcpdump -i vnet0 -n port 67 or port 68 tcpdump: WARNING: vnet0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vnet0, link-type EN10MB (Ethernet), capture size 65535 bytes 19:44:56.176727 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from fa:16:3e:46:f6:11, length 300 19:44:56.176785 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from fa:16:3e:46:f6:11, length 300 19:44:56.177315 IP 10.40.0.1.67 > 10.40.0.3.68: BOOTP/DHCP, Reply, length 319 19:45:02.179834 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from fa:16:3e:46:f6:11, length 300 19:45:02.179904 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from fa:16:3e:46:f6:11, length 300 19:45:02.180375 IP 10.40.0.1.67 > 10.40.0.3.68: BOOTP/DHCP, Reply, length 319 However, if I do the same thing on eth0 inside the KVM instance, I only see the request packets, not the reply packets.

  • ESXi 4.1 CentOS 6.X eth0 unnavailable

    - by L.K.
    I don't usually ask for help so directly, usually google have all i need but this time i'm seriously lost. Hope you can help me .s The thing is, i have a server with Vmware ESXi 4.1 and 5 already running and configured virtual servers, but whenever i try to make a new one on CentOS 6.X it leaves me without eth0 to be activated in any way. When installing CentOS, in the screen of localhost.localdomain i try by the button in the left down corner of the screen to make eth0 connect automatically but it tells me a NetworkManager Error: cannot start eth0. So...in command line once the CentOS is already installed, i have configured ifcfg-eth0 and manually tried to take up the eth0 but when i restart network service "Bringing up eth0: Failed" and sometimes even "shutting down eth0: Failed" Thanks in advance
