Hmm,
I just noticed that dump file saved using virsh contains some libvirt
related headers, so I guess I can't just feed it directly to qemu-kvm.
So I guess best way to test save/restore without libvirt is to save
vm state using monitor and then restore it again.
But I can't find any clear docume

Hi Ingo and Steven,

We have been trying to test qemu-kvm virtual machines under an IO load.

The 'autotest' kvm subtest was relying on autotest output, that

Is it expected that qemu-kvm-0.10.x doesn't build/install extboot.bin?
This came up on the IRC channel last night. I would expect it to, but
the person in the IRC channel didn't get extboot.bin from the tarball
and none of the tags of 0.10.x I tried built it either.
