Re: [libvirt-users] Can't take live snapshot, not supported with this QEMU binary
Under libvirt 1.1.1 snapshot support is incomplete.
Source:
http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_...
In regard to snapshotting (features and stability), I have selected these versions of
libvirt and qemu:
Libvirt >= 1.2.9 (currently 1.2.12)
Qemu = 2.1.0
On Qemu 2.3 and 2.4, I have experienced a regression bug regarding external snapshots. I
haven't tested 2.5 yet. I've read some ware about using an older qemu but I
can't find the webpage anymore. Sorry.

QEMU binary
Hi all,
I was trying to take live snapshot of VMs, but I got the following error:
[root@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
uname -r: 2.6.32-504.el6.x86_64
