ruby osx-mountain-lion libvirt
I bought a new Mac this week and have had big problems getting this gem installed. It was never a problem on my old Mac but seems to be particularly difficult on this one.I have installed libvirt via Homebrew, Xcode4.4 (with command line tools) and gcc4.2. I have symlinked to make gcc4.2 the default compiler.gem install ruby-libvirt -v ‘0.4.0’ fails because it cannot find the headersIf I pass in the paths to the headers and libraries, like so:ruby-libvirt -v ‘0.4.0’ -V — –with-libvirt-include=

timeout qemu libvirt kvm-virtualization
There’s a known issue with starting virtual machines with large hard drive images. Apparently, the time-out is 3 seconds, but in reality, it can take up to 15 seconds for a machine to start. I’ve read several bug reports, and people confirming it’s a time-out problem, but I have yet to see a solution.Is there an option I can pass, like:virsh start MyMachine –ignore-timeoutOr a config file that needs changed?Thanks!

python list virtual-machine libvirt
I am using virsh list to display the list of vms running on the computer. I want the information printed in the process in the form of a 2d array.One way to go about this is to have the output, use tokenizer and store it in the array. But is there some other way where I can get directly this into the form of an array or something so that code is much more scalable. (Something that I could think of was using libvirt api in python)

I’m having a problem with libvirt. On a system restart all virtual machines (VMs) are started without a problem and keep running. Then at some point in time a set of machines shuts down according to their log. When I try to restart the machine, I’m getting an error that the memory allocation failed, although more than enough memory is free.server ~ # freetotal used free shared buffers cached Mem: 16176648 16025476 151172 0 285432 950300 -/+ buff

virtualization kvm-virtualization centos6 libvirt
I use KVM/libvirt based virtualization. Some of vm guests have set date far in future (2-3 years, different month, day, etc) After each guest shutdown down, the date is being set to host date (kvmclock works that way). Is there any possibility to keep date during guest shutdown? It should work even guest won’t shutdown gracefully (crash, etc).Guest and host are recent version of centos 6.4.

centos installation kvm-virtualization pxeboot libvirt
The host server (running CentOS 6.0) only has one public IP address and will be hosting many KVM guests so it needs to use a virtual network switch configuration in NAT mode. I have previously used pxelinux for automated installation of physical machines and would like to continue to use pxelinux for installation of KVM-guests. The reason for this is that I already have written some scripts that generate pxelinux configuration files and I would like to reuse them.Could someone provide a step-by-

libvirt openstack
When I try to launch an instance with OpenStack, I get the following error in nova-compute.log:(nova.rpc): TRACE: libvirtError: operation failed: domain ‘instance-0000000a’ already exists with uuid 5f81a7d2-1b0f-8c72-4e1e-377c275e9289However, virsh doesn’t show any domains:$ sudo virsh listId Name State ———————————-Why isn’t that domain showing up in virsh if it’s there?

I would like some of my domains to start automatically when my host starts (I’m using libvirt+KVM on ubuntu). I guess I could put some “virsh start…” statements in rc.local, but is there a way to configure this within libvirt/virsh?

I have a Server running Ubuntu 10.10 Server-Edition kvm, and libvirt (both ubuntu-native packages) HDD-Partitioning was done with LVM. Then I created some VMs with Virt-Manager and assigned LVM-Volumes to the VMs. Now the VMs do not boot. Virt-Manager shows a CPU-Usage of 100% for this Guest and the VNC-Connection states Booting from Hard DiskThe VM-specific logfiles do not show any abnormality only syslog shows a warning warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status ‘1’, qemu

I have installed KVM on my Ubuntu system. Using vmbuilder, I setup a linux VM. When I tried to access the console using virsh console vm command, I was getting an error. I tried to follow the solution but, I cannot seem to be able to make permanent changes whatsoever to the configuration file. I tried both manually editing the xml config file as well as using the virsh edit command. But after I edit the file and close it, if I reopen the config file using virsh edit again, I get back the origina
