This patch improves the resilience of the load_vmstate() function, doing further and better ordered tests.
This patch broke restoring not-running VMs using libvirt-0.8.7 with qemu-0.14: When the domain is not running while taking a snpshot, the sn.vm_state_size == 0:
[...]
Previously the qcow2 image was still reverted to the old state, so on the next start of the domain the qcow2 image would be in the state of the snapshot
[...]
Now the qcow2 image is not reverted and when the domain is started, it is NOT in the state of the snapshot.
I can't decide if this regression is an Qemu bug or libvirt should be adapted to this new behavior.
Ouch. I wouldn't have expected that libvirt relies on this qemu bug. When libvirt doesn't use the VM state but boots a fresh VM, it should call qemu-img snapshot -a for the disks rather than using the loadvm monitor command. Kevin
