I've seen lots of non-sense with vmware.. This is one of the many... 1st, you need to confirm if issue is with vmware or cloudstack.
See what cloudstack tries to do, and replay the same activity through vmware client to see if it breaks at the same point. If it does, vmware needs a kick. This usually means - killing a vm world, or bouncing hypervisors - looking for file locks. On 1/21/16 3:52 PM, S.
