Hi all, I'm using ZFS on Linux block volumes as my VM storage and want to do live migrations between hypervisors. If I create ZFS snapshot of used volume on source host, send it do destination host (zfs send/recv) and then run live migration with VIR_MIGRATE_NON_SHARED_DISK flag, the migration works OK. But this procedure copies the whole disk twice which is a huge downside. The best solution would be, if libvirt could send the incremental data since last snapshot itself but this feature is not there (AFAIK). So I am thinking about a workaround: 1. Create snapshot...
