[libvirt-users] Can't take live snapshot, not supported with this QEMU binary

[Tashi Lu]

Hi all,

I was trying to take live snapshot of VMs, but I got the following error:

[root at localhost ~]# virsh snapshot-create-as 1 test desc --live
--memspec file=mem.bak,snapshot=external --diskspec
vda,snapshot=external,file=/root/root.bak.qcow2
error: Operation not supported: live disk snapshot not supported with
this QEMU binary

I upgraded my qemu-kvm 0.12.1 to qemu 1.2, the error still exists. Is
this really the problem of my qemu version or I did something wrong?
To what version should I upgrade? Thanks.

virsh version:
Compiled against library: libvirt 0.10.2
Using library: libvirt 0.10.2
Using API: QEMU 0.10.2
Running hypervisor: QEMU 0.12.1
