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.
