Is it possible to try Windows Server 2012 with VmWare Server 5.0?

I would like to try windows server 2012 rc using our vmware server 5.0 infrastructure. The problem is that i can't install it because each time, the virtual machine reboot. Is it vmware server 5 ready for win server 2012 ? Thanks

There is no product called VMWare Server 5.0, the latest version is 2.0.2, perhaps you mean VMWare's vSphere/ESXi 5.0?

If so then no, there's no support yet as Server 2012 isn't released yet (we don't generally deal with unreleased code on serverfault either by the way), but I know that once Server 2012 is released vSphere/ESXi 5.1 will support it within days/weeks of release.

If you had meant Server 2.0.2 then I wouldn't hold out for a patch any time soon, that's not a particularly active product these days.

It's possible to run Server 2012 on ESXi5.0 although it's not supported yet. VMWare even has KB entry for this problem:

TRY ONE OF THESE OPTIONS
Change the virtual machine to use EFI instead of BIOS:

Right-click the virtual machine and click Power > Shut Down Guest.
Right-click the virtual machine and click Edit Settings.
Click the Options tab.
Click Boot Options.
Click EFI under Firmware.
Click OK. 
Power on the virtual machine.

Add vmGenCounter.enable = FALSE to the .vmx file of the virtual machine:

Right-click the virtual machine and click Power > Shut Down Guest.
Right-click the virtual machine and click Edit Settings.
Click the Options tab.
Under Advanced, click General.
Click Configuration Parameters.
Click Add Row.
Under name, enter vmGenCounter.enable.
Under value, enter False.
Click OK to save the changes and then close the window.
Power on the virtual machine.

There's a decent article at http://www.virtuallyghetto.com/2012/02/how-to-run-windows-8-consumer-preview.html which also applies to Windows Server 2012.

The bottom line is that there are a set of patches to install first, then the rest is just configuration.
