Subject [QA] VMware HV Plugin Testing Question (Re: Issues when vCenter becomes unavailable)
Date Thu, 21 Feb 2013 14:39:12 GMT
Forward from the user list, hoping to catch the Citrix test engineering
team's attention.  Is this a tested scenario?

Andreas, 

The open source community doesn't support the Citrix version 3.0.6. You
need to report this via your Citrix Support contract. Sounds like this
could be a bug. 

Community - this could be a possible issue in 4.0.0 / 4.0.1. I don't know
if this test case has been explored.

Thanks,
Matt Mullins
