Hi, I followed this instruction: http://www.ovirt.org/documentation/how-to/hosted-engine/#upgrade-hosted-e... However, when I exited the global maintenance mode in step 7 and waited for about 15 minutes, the engine VM still doesn't migrate to the fresh upgraded host. BTW, after step 6, did I have to put the host out of its local maintenance mode? The instruction didn't state this so I guess it's a special case when upgrading and didn't do anything.
