VMware recently published an article on the Virtual Reality blog that raises some interesting points as to why VMware is better than Xen & Hyper-V.

Some of the areas that get particular analysis are:

• Uptime
• Direct driver model
• Memory management

More interesting still are some of the comments to post, have clearly been made by Citrix & Microsoft employees or people with a vested interest.

I find some of the points amusing, but my 2 penneth worth is thus:

• No VMotion or equivalent = not production ready

I think that this in itself is a good enough reason to use VMware over anything else.
