Subject Re: Can System VMs be migrated?
Date Tue, 10 Feb 2015 04:20:27 GMT
While creating a zone you can configure the use of local storage. It seems you configured it
erroneously.
In 4.3 as per my knowledge live vm migration with local storage is broken. Use it in 4,5 it
works I have tested it.
If you do not want to use local storage make sure you turn it off while creating the zone.
