Is it possible to setup a high availibility such as heartbeat that require 2 connections on one machine using vmware server?

What I think i want to do is installing the vmware server on a host machine. Then have 2 indentical vmimage (vmx) of a fedora linux running inside the server (host).

My plan is to create 2 virtual eternet connection between these 2 fedora vm. Is that possible to do so?

I think I know what you are saying, but correct me if I'm wrong.

I would not run 2 identical virtual machines simultaneously. What I would do is run the 1st Fedora VM, have the 1st Fedora VM be synced/copied up to another name or directory every X minutes, configure the heartbeat and scripts on the host machine to execute the vmware-cmd to execute the 2nd Fedora VM when the heartbeat stops between the host and 1st Fedora VM.

Or, you could purchase VMware ESX and it can do this for you. But you'll need a few thousand dollars to purchase a license.

I also understand that Xen has this feature? Someone correct me if I'm wrong.
