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.
