[QA] VMware HV Plugin Testing Question (Re: Issues when vCenter
becomes unavailable)
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,

I am sure this must have been covered as part of 3.0.6. Will go through internal escalation process if a case has been logged.
However I will get this checked out for ACS 4x version and will post the results.
