Background:
I had a server donated to me and its a IBM System x3550 M2 Xeon E5506 @ 2.13 GHz. I installed Windows Server 2012 because I was testing and messing around with it. I was going to install ESXi 5.1 but for some reason I was not able to get the server to read off any ESX media I put in it, (CD, USB...).
So I am currently using WS 2012 and I have VM Workstation installed for creating some virtual machines and all went well.
Issue:
I went to boot my machines the other day, and I got an error saying "64-bit guest operating systems are not supported by this host and will not run."
This did not make sense. I rebooted and checked the bios, the setting is enabled and I saved the settings and I'm getting no where with this issue.
I even upgraded the firmware on this box and enabled the setting again and nothing... Virtualization worked before and now its not working, I'm stumped.
