Hi everyone, Using the QEMU hypervisor, when a live disk snapshot is requested through libvirt, the request can fail if the underyling qemu binary lacks the snapshotting support. In python, we have something like libvirtError: Operation not supported: live disk snapshot not supported with this QEMU binary I'd like to detect ahead of time if the underlying QEMU can or cannot do

I have successfully (I believe) built (rebuilt on Ubuntu 14.04), installed, and used libvirt 1.2.2. Behaviorally I can't tell the difference between what I've built and what Ubuntu distributes. Specifically, "virsh capabilities" shows this: <secmodel> <model>apparmor</model> <doi>0</doi> </secmodel>

Hi, All The vm can't start when using numa based on centos 6.5(kernel: kernel-2.6.32-431.17.1.el6.x86_64, qemu-kvm: qemu-kvm-0.12.1.2-2.415.el6_5.8.x86_64). My numa setting in vm xml is the following: -------------------- <numatune> <memory mode='strict' nodeset='1'/> </numatune> -------------------- When 'nodeset' sets '0', the

Tried to migrate a few VMs from existing system to an older host that we threw in the rack to facilitate some server reshuffling. Migration complained about lack of capabilities (which I expected its an older server) but when I looked at what I should throw into the xml file I got a core2duo when it should have been at least Penryn or something (Xeon E5345) Of course the VMs work fine with

I am using libvirt 0.10.2.2 and qemu-kvm 1.2.2 (qemu-kvm 1.2.0 + qemu 1.2.2 applied on top plus a number of stability patches). Having issue where my VMs fail to start with the following message: kvm_init_vcpu failed: Cannot allocate memory Following the instructions at http://libvirt.org/formatdomain.html#elementsNUMATuning I've added the following to my VCPU configuration: <vcpu

I hope this question isn't considered too off topic for this list, I am trying to reach the libvirt-sandbox developers, but I could not find a libvirt-sandbox specific mailing list, and it seemed to me that libvirt-sandbox was a part of libvirt itself. I am trying to port libvirt-sandbox to run on a CentOS 6.5 system. This wasn't too hard but, I had to do the following: I have used the

Hi all I have faced this issue already and the solution was to go back to a old version of qemu-kvm and/or libvirt and things start falling into place but this time I would want to solve this. I have used these versions as per the o/p of the commands below. To jumpstart a new machine which is libvirt capable, it always is a hastle to find out which of the version combination of

I am using nested virtualization on a Google Cloud Compute instance. Things are generally working fine with libvirt using qemu+kvm, however I observed that <cpu mode='host-model'> is not exposing avx and avx2 instruction set to the guest Linux instance. Google Cloud platform claims the CPU model of the host compute instance is Broadwell, however libvirt capabilities maps it to

Hello Community, I successfully installed and run xen (xm list and xm info can output appropriately). However, while I was installing domU image by using virt-install -p at domU OS. I encountered an error information" Host does not support virtualization type ''xen'' ". I built xen from source. Some of my friends have the same issue, but if they use pre-build xen, the

Dear R users, I am pleased to announce that QGA 1.0 is now available on CRAN. QGA implements the Quantum Genetic Algorithm, as proposed by Han and Kim in 2000, and is an R implementation derived from the Python one by Lahoz-Beltra in 2016. Under this approach, each solution is represented as a sequence of (qu)bits. Simulating the quantum paradigm, these qubits are in a superposition state:

Hi, I cannot have suspend and hibernate working on a Samsung NC10 (netbook) running CentOS 5.4 i386. When I try suspending/hibernating the screen becomes black (with a few logs, like "shrinking memory" for hibernate) and then the computer hangs and I have to force a shutdown with the power button. This wiki page seems to say that it should work out of the box:

Hello list, my name is Matteo, i'm new on that list. I'm working on a multitenancy platform with linux containers through libvirt on a production system with Red Hat 6.4.

Where can I find the full list of libvirt supported qemu-ga commands? The docs [0] imply virDomainQemuAgentCommand bypasses libvirt and is not recommended. I am looking to pass suspend/resume events from the host to the guest and then have the guest act on this internally. Your help is appreciated. [0] https://wiki.libvirt.org/page/Qemu_guest_agent
