Re: [ovirt-users] Actual downtime during migration?

its memory resynchronised one last time

Actually, thinking about it, rather than diffing *all* of the memory on the first host to resync it at the last moment, the hypervisor probably simultaneously copies the current state of memory & uses copy-on-write (COW) to write all new transactions to both hosts. Only a technical difference, but it'd greatly reduce how long the VM needs to be paused to complete a full sync. -- Doug
