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

Hi, I tried to run domsuspend command on my PowerPC board but failed. # virsh dompmsuspend sdk --target mem error: Domain sdk could not be suspended error: argument unsupported: QEMU guest agent is not configured It seemed that support suspend-to-mem only from capabilities. # virsh capabilities <capabilities> <host>

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

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

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

Hi all, I have been trying to find out cpu topology using libvirt. When I do 'virsh capabilites', I find this inside <topology> tag: <topology>       <cells num='1'>         <cell id='0'>           <memory unit='KiB'>3908488</memory>           <cpus num='4'>             <cpu id='0' socket_id='0'

Hi, I have been trying to find out CPU topology using libvirt. I understand that I can find out the number of cores/sockets/ threads etc through getCapabilities() function. What I am wondering is that is there any function that can provide me the exact topology like how many sockets, how many sockets per core and number of threads per core, if applicable or may be info about numa cells.  Is there

Hi, Please let me know in case I am posting my question to the wrong forum. I apologize if that is the case! Here is my question: We run CentOS 6.3 on a server with dual Xeon CPU's. Our "dual blade" server uses this motherboard: http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRT-HF.cfm We have two of these CPUs installed and working: Intel(R) Xeon(R) CPU E5-2620 0 @

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>

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. Every container run a separate instance of OpenSSH and Apache HTTPd and I need to give root privileges to the developers and I try to configure SELinux using svirt and MCS. I try the secmodel type dynamic and static in

Hello, so the current domain configuration: <cpu mode='host-passthrough'><topology sockets='8' cores='4' threads='1'/><numa><cell cpus='0-3' memory='62000000' /><cell cpus='4-7' memory='62000000' /><cell cpus='8-11' memory='62000000' /><cell cpus='12-15'

First I'll quickly summarize my understanding of how to configure numa... In "//memoryBacking/hugepages/page[@nodeset]" I am telling libvirt to use hugepages for the guest, and to get those hugepages from a particular host NUMA node. In "//numatune/memory[@nodeset]" I am telling libvirt to pin the memory allocation to the guest from a particular host numa node. In
