Non-shared storage migration of guests which are disk I/O intensive and have fast local storage may actually never converge if the guest happens to dirty the disk faster than it can be copied. This patch introduces a new flag 'VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES' which will instruct hypervisors to synchronize local I/O writes with the writes to remote storage used for migration so that the guest can't overwhelm the migration. This comes at a cost of decreased local I/O performance for guests which behave well on average. Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com> |
