[libvirt-users] Can't take live snapshot, not supported with this 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
Under libvirt 1.1.1 snapshot support is incomplete. Source: http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_won't_let_me_delete_or_revert_to_it 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.

Thanks Ramaekers, I'm now using libvirt 1.2.21, qemu-kvm 1.2.0 and live snapshot works. I'll try out different versions of libvirt and qemu and see the differences between versions. On 19 November 2015 at 18:18, Dominique Ramaekers <dominique.ramaekers@cometal.be> wrote:
