Dirty-bitmaps are lost if VM is stopped or migrated, if I understood 
correctly?

If so, leaks would be cleared on next node reboot (version upgrade or 
new kernel installed).

But I understand the issue. Maybe a check in advanced settings of PBS 
storage with a warning to request a storage-speciffic dirty-bitmap...? :)

Thanks!
