That shouldn't be happening - a start after a managedsave should be restoring the guest to the same state as at the save. It sounds like you may have run into a corrupted managedsave file, so libvirt punted and booted the guest from scratch instead of restoring state; booting from scratch without a clean shutdown would explain the symptoms of the OS complaining.
Did you upgrade qemu in between when you saved your guest and restarted it? If so, this may be more of a qemu bug about not handling incoming migration of data generated from an older qemu. Are you sure that the managed save data was not corrupted, such as a power outage occurring before the managed save file was completely flushed to disk?
I use a script started each night to (managed)save the guests and upload them to a FTP server. Basically, I do virsh managedsave guest <upload managedsave file> <upload guest disks> virsh start guest So, there is no qemu update and the hypervisor uptime is pretty high. I'll investigate on the corruption possibility. Thanks for your feedback. -- Nicolas Sebrecht
