Re: HA issue and Xen resets

[Garith Dugmore <ga...@saao.ac.za>]

Update:

I've reinstalled everything below just incase I missed something but still no luck with my test instance coming up on my second xen host once the network cable has been yanked. 

Any recommendations or points will be greatly appreciated.

Pulling my hair out here...

side note: This recipe here -> http://discussions.citrix.com/topic/347884-automatic-applying-patches/ works well for updating Xen hosts from the CLI.
