Hi all,
It seems live snapshot is available in the Fedora 17 qemu-kvm. On my
laptop with kvm, virt-manager, libvirt, virsh etc. I created a virtual
machine and tried to make a live snapshot:
virsh -c qemu:///system
Welcome to virsh, the virtualization interactive terminal.

1340871802 2012-06-28 10:23:22 +0200 running
Both my laptop and the Virtio vdsm machine are using the same package:
[root@kvm ~]# rpm -qf `which qemu-kvm`
qemu-system-x86-1.0-17.fc17.x86_64
[wdh@laptop-winfried ~]$ rpm -qf `which qemu-kvm`
qemu-system-x86-1.0-17.fc17.x86_64

this is the relevant error coming from libvirt.
maybe fedora 17 qemu-kvm does not have live snapshot support?
