Hopefully the improvements made in clustering with Windows Server 2008 will make Melio FS setup with Hyper-V much simpler. As for TechNet...I'll bite my tongue on that one. :-) Phil,

The document also references a couple of Technet docs which I tried to access, but alas Technet was not responding. Maybe the parent partition had issues or they were patching it ;) Phil Scott, I just checked out the Sanbolic doc on setting up MS VirtualServer 2005 using MelioFS to enable “Live” migration and I must say its not easy (http://www.sanbolic.com/pdfs/MSCS_Virtual_Server_Configuration_Guide.pdf).

I know that everyone reading will find that useful. In response to your question, Brett, I think we all know why marketing never matches reality--if it did, sales would be a LOT lower than they are otherwise. NateL, Brett,

In response to your question, Brett, I think we all know why marketing never matches reality–if it did, sales would be a LOT lower than they are otherwise.

The requirement of a lun for every VM is something I would expect from a very immature product. Surely MSFT is better than this. No clustered filesystem is a showstopper.

Despite the fact that VMware has a technical lead, they will have to continue to innovate heavily to beat being "good enough." The one area Microsoft does have a leg up on VMware is in the management strategy. Again, using SCVMM 2008 to federate multiple VC instances gives Microsoft a "trojan horse" into the virtualization environment, opening the door for Hyper-V. Duncan, John,

And relying on a partner to fill this gap seems to easy, it seems to me if they did not have time enough to develop this themselves and came up with an easy way out. In the end Hyper-V is not even near the capabilities ESX has today. It's a good start but they've got a long road ahead. A lun for every VM will not make things easier indeed.
