I'm planning to build a small server for a couple small projects, which will run a couple OSs as virtual machines.
This will mostly be Windows OSs, so I decided to use the new Hyper-V functionality added in Server 2008.
What I've recently learned about is that Microsoft have their own Hypervisor os, based on the Hyper-V technology. This would be a great solution, but it seems there are a number of drawbacks. Mainly - there's hardly any information about it, and the download links have been removed from the Hyper-V website (even though they're still available at the download center). It looks like it's been buried.
Secondly - the Windows Server 2008 R2 SP1 just came out, adding new functionality, like Hyper-V Dynamic Memory.
So the question would be: Is there any use in still using microsofts hypervisor, or should I use the full server 2008 R2 os + a number of VMs on it?
Should I use a different hypervisor instead? (like VmWare ESX..)
