I am running KVM on Centos 6.3 and am seeing an unexplained shut down of two guests. The libvirt package was upgraded to libvirt-0.10.2-18.el6_4.4.x86_64 at the time of the shutdown. Only the two guests shown below was affected, while 9 others running on the same hypervisor were not. Can some one help me to find the cause please ? Regards Chandana GUEST #1 ======== 2013-04-10

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out. Any guidance in this regard would be a great help.

Hello. I've been tesing VGA passthrough using libvirt. However, My *Windows7*(64bit) Virtual Machine stopped at loading screen as soon as I installed graphic driver(*AMD Radeon HD 7750*) and then restarted the VM. How Can I use VGA passthrough technology in my *Windows7* VM? I attached my testing information(HW, system environment and settings, qemu log and so on..) Best Regards.

Dear all, I install centos 6.3-64bit in a new server and also installed KVM using yum. Then I create a new virtual machine(i686) to install windows xp, but it's very slow, do you know why? Server: CPU: i7 3370, Memory: 16GB. Virtual machine: 1 cpu and 1GB ram. type: i686 KVM information: qemu 4223 1 9 15:10 ? 00:00:41 /usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu

I've "ported" an old VMware VM containing Windows NT 4 SP6 into libvirt/kvm/qemu and got it running (more or less). However, the CPU graph next to the VM in virt-manager shows it starts using 100% of the allocated CPU as soon as it reaches the "OS Loader" screen, and stays there even after Windows has booted and I've logged in. (There's a dip now and then,

Hi, On a DELL r610 (Intel Xeon L5520) and a Windows guest I have an hardware error. The bug is well known[1][2] and seems fixed with the package 3.5.0-16-generic. But I use 3.5.0-30-generic. Do I need to upgrade to 13.10? Or just the kernel ? Or modify the options of the kvm module? Thanks. [1] https://bugzilla.redhat.com/show_bug.cgi?id=854983 [2]

Hi Daniel, I have noticed that it will fail exactly as you said if <cdrom> is first in the boot order, if <hd> is first in the boot order the XML validates and it starts as usual. first in log except below is with cdrom set to first in boot order, second is with hd set first. 2018-08-09 11:39:28.625+0000: starting up libvirt version: 3.9.0, package: 14.el7_5.6 (CentOS BuildSystem

Hi All. I'm trying to setup a guest within my hypervisor that acts as a Console Server, using 10 USB to Serial adapters. The Host is all setup and can access each Serial Port without problems. I have attempted to add the Serial Connections to a Guest, using both Virtual Machine Manager and by editing the .XML file, and I can add up to 4 Serial devices (Including one for console access to the

Hi everyone: I am new here I am using kvm and libvirt on my Dell server. Now i am trying to migrate one virtual machine from a physical server to another. However, I failed everytime.

Hello. It's my first time here, so I'm so sorry if I make mistakes with how I'm sending or posting this. I wanted to ask about some problems I've found with other people, working with libvirt. We wanted to create a new virtual machine under MIPS architecture, using Qemu and libvirt. We are able to create the machine, and it boots, but never gets an IP. I'll leave the commands

Hello, I'm using virt-manager on my F23 box to run a Windows 10 image but the performance is so bad it's killing me.

Hi, i have a SLES 11 SP2 64bit host with three guests: - Windows XP 32 - Ubuntu 12.04 LTS 64bit - SLES 11 SP2 64bit The SLES guest shuts down with the host shutdown. The others not. When i shutdown these two guests with the virt-manager, they shutdown fine. ACPI is activated in virt-manager for both of them. Acpid is running in the Ubuntu Client.
