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.

'quit' to quit

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
dave - who can help us elaborate on this libvirt error:
reuse is not supported with
this QEMU binary
Thanks,
Itamar

BTL, sanlock is disabled in qemu.conf (#lock_manager="sanlock"), I
cannot install a vm when it's enabled. Is that related?
this is the relevant error coming from libvirt.
maybe fedora 17 qemu-kvm does not have live snapshot support?
