  • Disk IO causing high load on Xen/CentOS guest

    - by Peter Lindqvist
    I'm having serious issues with a xen based server, this is on the guest partition. It's a paravirtualized CentOS 5.5. The following numbers are taken from top while copying a large file over the network. If i copy the file another time the speed decreases in relation to load average. So the second time it's half the speed of the first time. It needs some time to cool off after this. Load average slowly decreases until it's once again usable. ls / takes about 30 seconds. top - 13:26:44 up 13 days, 21:44, 2 users, load average: 7.03, 5.08, 3.15 Tasks: 134 total, 2 running, 132 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.1%sy, 0.0%ni, 25.3%id, 74.5%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 1048752k total, 1041460k used, 7292k free, 3116k buffers Swap: 2129912k total, 40k used, 2129872k free, 904740k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1506 root 10 -5 0 0 0 S 0.3 0.0 0:03.94 cifsd 1 root 15 0 2172 644 556 S 0.0 0.1 0:00.08 init Meanwhile the host is ~0.5 load avg and steady over time. ~50% wait Server hardware is dual xeon, 3gb ram, 170gb scsi 320 10k rpm, and shouldn't have any problems with copying files over the network. disk = [ "tap:aio:/vm/dev01.img,xvda,w" ] I also get these in the log INFO: task syslogd:1350 blocked for more than 120 seconds.

  • Tool that will virtualize BIOS

    - by Nrew
    Is there any application that can virtualize the BIOS?So that you can see the effects of what the changes in the setting of your BIOS. I know that there are many versions of BIOS depending on your hardware. But is it possible to copy it and then virtualize it when you are running your system. So that you can see if your system can still run after changing the settings.

  • ESXi 5.1 on Poweredge 510 freezes after base-esx update

    - by goober
    Background / Problem Just experienced an issue where an ESXi host was upgraded from 5.0 -- 5.1 perfectly fine. Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully. However, on reboot, the server hangs at the "Initializing Power Management" phase. I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :) Question Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?

  • Is it generally a bad idea to have other types of virtual appliances installed along side a firewall

    - by MGSoto
    I want to run my Firewall/NAT software (pfsense) and an internal NAS (looking at freenas right now) for my SOHO on one machine. Right now I have them separated on two different machines, but I'd like to consolidate them. Is this generally a bad idea? I see the security concern where if the firewall or host OS is compromised, then your data is essentially screwed. But is it really a concern for me?

  • OpenVZ Can't initialize containers after install

    - by Tonino Jankov
    I have installed OpenVZ on centos 6 on a dedicated server. I followed quick installation guide on openvz wiki. After installing thru yum, I don't know why, but grub.conf wasn't automatically updated to accomodate new kernel, so I had to do it manually. I edited grub.conf, added openvz kernel and rebooted - it went fine. Server went up into openvz kernel and it worked, it started openvz service byitself. But after I created a container, added IP to it and attempted to start it, I couldn't. Here is the output from the shell: [root@cloud2 ~]# vzctl start 86 Starting container ... Container is mounted Container start failed (try to check kernel messages, e.g. "dmesg | tail") Container is unmounted [root@cloud2 ~]# dmesg | tail [ 1973.401596] CT: 86: failed to start with err=-105 [ 2107.113850] Failed to initialize the ICMP6 control socket (err -105).

I tried different templates, debian 6, centos 6, i386, amd64, but the issue is the same. What is the problem?

  • IPv6 Routing / Subnetting

    - by nappo
    Recently I have installed Citrix Xen Server 6.2 on a machine. My Provider (Hetzner) gave me the IPv6 Subnet 2a01:4f8:200:xxxx::/64. Followed an article in the providers wiki (1) i got it working and can assign IPs to my guests (CentOS). However i can't assign a second IP to a single guest - it will result in a timeout. I'm not very familiar with IPv6 routing / subnetting - any help or tips for further troubleshooting is welcome! My Setup: XenServer 6.2 IPv6: 2a01:4f8:200:xxxx::2/112 ip -6 route: 2a01:4f8:200:xxxx::/112 dev xenbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 default via fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 Guest 1 IPv6: 2a01:4f8:200:xxxx::3/64 IPv6: 2a01:4f8:200:xxxx::4/64 ip -6 route: 2a01:4f8:200:xxxx::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::1 dev eth0 metric 1 mtu 1500 advmss 1440 hoplimit 4294967295 Guest 2 IPv6: 2a01:4f8:200:xxxx::5/64 Guest 1 IPv6 is working fine, Guest 2 too. As suggested by the wiki article (1) i split my /64 network into a /112. Is it right to set the host /112 and the guests /64? Why is that?

  • How to subnet hosted VMs

    - by bwizzy
    I have a network of VMs each having a LAN IP address and a public IP address. They each have a 1:1 NAT map for public access via the public IP for HTTP, SSH etc. I'm trying to figure out a way to restrict the LAN IPs from talking to each other, but there are some cases where a group of LAN IPs will need to communicate. I'm using pfSense as a firewall / router on a 192.168.0.0/24 configuration. It seems like I could assign each VM it's own subnet and add a static route to the firewall for that VM to get back to the firewall for internet access / other fw rules. Is that right? I assigned 1 VM with: address 192.168.1.2 netmask 255.255.255.254 gateway 192.168.1.1 Then added a static route on the FW's LAN interface using 192.168.1.0/30 as the destination network and 192.168.1.1 as the gateway. Nothing appears to be working, anyone have any ideas? Please be aware I'm not that familiar with subnets. Thanks!

  • Baseline / Benchmark Physical and virtual server performance

    - by EyeonTech
    I am setting up a new server and there are some options. I want to perform some benchmarks and I need your help in determining the best tools and if possible run pre-configured benchmarks designed for SQL servers on Windows Server 2008/2012. Step 1. Run a performance monitor on the current Live SQL server (Windows Server 2008 Virtual machine running on ESXi. New server Hardware rundown: Intel® Server System R1304BTLSHBN - 1U Rack, LGA1155 http://ark.intel.com/products/53559/Intel-Server-System-R1304BTLSHBN Intel Xeon E3-1270V2 2x Intel SSD 330 Series 240GB 2.5in SATA 6Gb/s 25nm 1x WD 2TB WD2002FAEX 2TB 64M SATA3 CAVIAR BLACK 4x 8GB 1333MHz DDR3 ECC CL9 DIMM There are several options for configurations and I want to benchmark some of them and share the results. Option 1. Configure 2x SSDs at RAID 0. Install Windows Server 2008 directly to the 2TB WD Caviar HDD. Store Database files on the RAID 0 Volume. Benchmark the OS direct on the hardware as an SQL Server. Store SQL Backup databases on the 2TB WD Caviar HDD. Option 2. Configure 2x SSDs at RAID 0.

  • Can Xen be configured to dedicate only one port of a dual-port NIC to a domU?

    - by jamieb
    I'm using CentOS 5.4 on my dom0 with a stock Xen kernel. I'm attempting to use the pciback module to hide some of the Ethernet ports from the host and reserve them for a domU I intend to use for a firewall (process described here). However, when I launch the domU, I get the following error message: Using config file "/etc/xen/firewall". Error: pci: improper device assignment specified: pci: 0000:01:04.0 must be co-assigned to the same guest with 0000:01:06.0, but it is not owned by pciback. lspci gives me the following output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • VirtualBox in production?

    - by MrG
    I'm planning to move a service which is currently powered by Debian into a VirtualBox. That would allow us to easily port it i.e. to a faster machine if required. The setup would be: debian host > Virtual Box #1 > debian instance #1 running Apache & application > Virtual Box #2 > debian instance #2 containing database Do you have any experience with a production setup based on Virtual Box? Is it stable and fast enough? Many thanks!

  • Cannot change PostgreSQL port

    - by Jerec TheSith
    I run Postgresql 8.4 as a service on a CentOS 6.2 server. I set port = 21444 and listen_addresses = '*' in /var/lib/pgsql/data/postgresql.conf and I changed 5432 to 21444 in postmaster.opts and restarted postgres, but when I run netstat -lntp postgresql is still running on port 5432 tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 20276/postmaster When I restart postgresql I get a writting error warning on /proc/self/oom_adj, but the service starts anyway. I read that we could get this error when using virtualized servers, but I don't really know if this has inpact on postgresql listening port. The correct pgsql config file is loaded in /var/lib/pgsql/data : [root@srv02 ~]# ps -ef | grep postgres root 1358 22140 0 09:42 pts/0 00:00:00 grep postgres postgres 9519 1 0 Mar16 ? 00:00:01 /usr/bin/postmaster -p 5432 -D /var/lib/pgsql/data postgres 9573 9519 0 Mar16 ? 00:00:00 postgres: logger process postgres 9575 9519 0 Mar16 ? 00:00:05 postgres: writer process postgres 9576 9519 0 Mar16 ? 00:00:03 postgres: wal writer process postgres 9577 9519 0 Mar16 ? 00:00:01 postgres: autovacuum launcher process postgres 9578 9519 0 Mar16 ? 00:00:01 postgres: stats collector process any thought ? thanks, Jerec

  • Can KVM CPU assignment count differ from physical hosts CPU count?

    - by javano
    I have read this question. I knew already that I could for example, have a quad core machine with four guests each having two vCPUs. As they don't all be require 100% CPU usage all the time, the scheduler would handle this for me. My question is about how this relates to a fail-over or migration situation; If host1 has two dual-core CPUs, and I assign guest1 four vCPUs (so it accessed all four physical cores), what will happen if I try and migrate it to host2 which only has one dual-core CPU? Can qemu-kvm emulate more vCPUs than there are physical? Or would I have to shut down the virtual machine, change the CPU assignment, migrate it, and then boot it back up (so no live migration)? Many thanks.

  • File Not Found error launching Guest OS in a non-administrator user account

    - by ToreTrygg
    Hi, I am running Fusion 2.0.6 (196839) on an iMac running 10.6.2 with 3 user accounts (1 Administrator). I have Fusion set up to share the Guest OS, and it's been working splendidly for nearly a year. Within the Guest OS (Windows XP PRO), there are also 3 user accounts (1 Administrator). Last night I went to back up my VM to an external drive, and to minimize the file size and transfer time, I deleted all Snapshots but the most-recent one. I then backed up the VM externally (28.23 GB). Today, one of my users tried to launch the Guest OS from within her user account, and received the following error message: "File Not Found: Windows XP Pro-000006.vmdk "This file is required to power on this virtual machine. If this file was moved, please provide its new location." My two choices are Cancel and Browse. When I browse, I can locate the Windows XP Pro-000006.vmdk file, which appears to be contained within the VM file (Windows XP Pro.vmwarevm). However, it still won't launch from a non-Admin user account. If I view the package contents of the VM file from the user account, the above file is present and appears to be created upon each launch of the Guest OS. If I go back to my Administrator account on the Mac and then launch Fusion, the Guest OS works perfectly for all 3 user accounts within XP Pro. I have tried to delete the Guest OS from Fusion's Library within the problem user account, then re-connect it to that Library, but the result is the same. The Guest OS data integrity is 100% -- but is accessible only from the OS X Administrator account. This problem only surfaced after deleting several older Snapshots. Again, the data is there, the Guest OS powers up normally in the Mac's Administrator account, but persistently returns the above error when attempting to power on from a non-Admin account on the Mac. I'm not sure how this is affecting the error, but when I look at Hard Disk Settings, the "unable-to-locate" file is the filename of the virtual HD. I don't want to make any changes to my (working) VM without any advice from the knowledgeable people on this forum. Any help will be greatly appreciated, thanks!

There are several linux guest running fine on the node (centos, debian, ubuntu, arch), and even Windows 2003 x86 also running fine. But Win2008 does not. I wonder, what's the difference. From Win2008 guest I can ping nothing: neither gateway, nor any other IP, even they are in the same subnet. From outside I also cannot ping guest. Almost. If I ping it from another server in same subnet, it's barely pinging, losing more than 90% packets. Firewall on the guest is completely off. Tried to set up network manually as well as via DHCP without success (BTW, DHCP set up network settings correctly). I suspect that is a kind of routing problem, but I spent whole day and still cannot figure it out. I would be appreciate for any help.

  • Xen on bare metal, Mac OS X 10.6, Vista, Debian as guest OSes

    - by Mischa Arefiev
    I have: a desktop PC (Athlon 64, 2 cores) ...that came with Windows Vista, and a retail DVD of Mac OS X 10.6 I want: to install Mac OS X through Hackintosh (I believe my hardware is suitable), to also run Windows Vista with full 3D support for video games and Youtube, to also run Debian GNU/Linux with optional 3D for work. I don't think my CPU supports VT-x, but it should have AMD-V. So the question is: Can all of this be done with Xen (Xen on bare metal, all three OSes as guests)? Or should I just try to install OS X first and then run Vista and Debian in Parallels?

It would be great, when i will be able to access my http://localhost:3000 from Windows, sitting in virtual environment (Parallels). How to wire all the stuff up ?

  • Free tiered storage automation in linux?

    - by NginUS
    I have a couple virtualized fileservers running in QEMU/KVM on ProxmoxVE. The physical host has 4 storage tiers with significant performance variances. They're attached both locally and via NFS. These will be provided to the fileserver(s) as local disks, abstracted into pools, and handling multiple streams of data for the network. My aim is for this abstraction layer to intelligently pool the tiers. There's a similar post on the site here: Home-brew automatic tiered storage solutions with Linux? (Memory - SSD - HDD - remote storage) in which the accepted answer was a suggestion to abandon a linux solution for NexentaStor. I like the idea of running NexentaStor. It almost fits the bill. NexentaStor provides Hybrid Storage Pools, and I love the idea of checksumming. 16TB without incurring licensing fees is a huge plus as well. After the expense of the hardware, free is about all my budget can handle. I don't know if zfs pools are adaptive or dynamically allocated based on load, but it becomes irrelevant since NexentaStor doesn't support virtio network or block drivers, which is a must in my environment. Then I saw a commercial solution called SmartMove: http://www.enigmadata.com/smartmove.html And it looks like a step in the right direction, but I'm so broke I'd be wasting their time to even ask for a quote, so I'm looking for another option. I'm after a linux implementation that supports virtio drivers, and I'm at a loss as to which software is up to it.

  • Install a KVM guest with LVM partitioning on an LVM partitioned host using virt-install fails, volume group already exists

    - by Rilik84
    our setup consists of a ubuntu 10.04 kvm host server with LVM, on top of which we install the ubuntu 10.04 virtual machines via virt-install and preseed. Each VM has a dedicated logical volume which we pass to virt-install via the "--disk path=/dev/sysvg/vm-name" parameter. The virtual machines themselves are using LVM as well. Virt-install seems to have a few issues with this setup. Say we want to install two virtual machines in parallel. The first vm installs correctly while the second halts during the partitioning, complaining with this error: "volume group name already in use". I tried removing the logical volumes, recreated them, rebooted the kvm host to clear any leftovers but the issue perists. The preseed is telling the vms to create a volume group named "sysvg", which is the same name used by the volume group of the kvm host. Considering this I did another test: I got rid of the preseed part taking care of the partitioning/lvm creation and started the creation of two vms in parallel. If, when prompted, I instruct the vms' installer to do a guided partitioning of the disk with LVM, it will still fail giving this different error on both the vms: Physical Volume /dev/sda5 is already in volume group sysvg. As I wrote, sysvg is the volume group used by the KVM host. So I thought the name clashing was the issue. By removing the preseed part I skipped the volume group naming. I can't understand how the virtual machines would be aware of the presence of that volume group since they're supposed to be isolated from it, especially after I removed and recreated the logical volumes dedicated to them. That detail should not be exposed at all to them! Thanks for the help. I'm clueless.

  • Problems connecting Centos to the network when running in VMWare

    - by Sakin
    Hi, I installed CentOs on VMware running on windows XP. When trying to configure it to connect to the internet, I get an error message when trying to bring up the network interface: [root@VMLinux ~]# /et/init.d/network start Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0... failed [FAILED] VM is running on a machine that has access to the network, I tried it on two different networks that have DHCP enabled. I tried to configure VMWare to use a bridged connection as well as NAT connection. An image of Ubuntu runs fine on the same VMware. What am I missing here? Thanks.
