Assigning more than one virtual CPU
If you are running Citrix XenServer EE
5 Update 2 on a Windows® 2008
EE SP1 (x84-64) virtual machine, you can experience the Windows stop message if you configured more
than one vCPU.
Multiple Citrix XenServer hosts
If you are running multiple Citrix XenServer hosts
as part of a shared resource pool, one of the hosts can become unresponsive
when you are doing SAN Volume Controller actions,
such as adding and removing nodes, or resetting nodes.
