[Users] Failed to migrate host

Hello, I got an error when trying to migrate a VM. On the "events" tab on the bottom it said. Failed to MigrateStatusVDS, error = Could not connect to peer VDS (VM: <vmname>, Source Host: <Hypervisor Host>). In the engine log it says the following. 2013-02-05 22:09:24,606 ERROR [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (QuartzScheduler_Worker-66) Rerun vm 6a9178cc-56cf-42f3-8a4c-098095d737f9.
