Abstract
Examples maintain consistency of writes for a plurality of VMs during live migration of the plurality from a source host to a destination host. The disclosure intercepts I/O writes to a migrated VM at a destination host and mirrors the I/O writes back to the source host. This 'reverse replication' ensures that the CG of the source host is up to date, and that the source host is safe to fail back to if the migration fails.
