Can I use cluster suite from xen or vmware?
Yes you can. For example, you could have a single computer, running Xen virtualization, act as a complete cluster consisting of several xen guests. There are special fencing issues to consider. For example, if you use power fencing, one guest could cause the whole machine to be powered off and never come back (because it wouldn’t be alive to tell the power switch to power back on). There is a special fencing agent designed to reboot xen guests as needed. You can also create clusters made of several computers, each of which has several virtual xen guest nodes. This has other fencing complications. For example, a xen guest can’t use a simple xen fencing agent to reboot a xen guest that’s physically running on a different physical computer.
