Libvirt can't do live snapshots if the underlying qemu cannot. Since you are using CentOS, I'd look into finding the qemu-kvm-rhev package (the default qemu-kvm package is intentionally shipped with fewer supported features, and you have run into one of those features). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
Hi, The package installed is qemu-kvm-1.5.3-60.el7_0.10.x86_64 on CentOS 7. I have upgraded my libvirt and qemu also, still i am getting the same error ( Operation not supported: live disk snapshot not supported with this QEMU binary ) # virsh version Compiled against library: libvirt 1.2.10 Using library: libvirt 1.2.10 Using API: QEMU 1.2.10 Running hypervisor: QEMU 2.0.0 On Mon, Nov 24, 2014 at 9:52 PM, Eric Blake <eblake@redhat.com> wrote:

You need qemu-kvm-rhev, not plain qemu-kvm.

Quoting Paolo Bonzini's earlier mail (https://lists.gnu.org/archive/html/qemu-devel/2014-11/msg03379.html): Luckily, since you are using CentOS you do not really care about official Red Hat RPMs, and you can get the packages here: http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/ This yum repository file will help: [qemu-kvm-rhev] name=oVirt rebuilds of qemu-kvm-rhev baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/ mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server enabled=1 skip_if_unavailable=1 gpgcheck=0 Drop it in /etc/yum.repos.d/qemu-kvm-rhev.repo and install qemu-kvm-rhev with yum. All features will be available. It would be simpler to have a CentOS SIG build this, but it hasn't happened yet. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
