I'm not off to a good start :-( As soon as I try to boot the VMware virtual machine I get this:
I'm trying to install the 64-bit version Ubuntu server. The host machine is a Dell PowerEdge 2950 with dual quad-core 64-bit Xeons. I've got a choice: I can down the server - and all the virtual servers running on it, of course - and check the BIOS settings or just download the 32-bit version.
Installing the 32-bit version of Ubuntu Server wouldn't get to the bottom of the problem, so I went for a reboot and checked the BIOS. Sure enough, vitualization support was disabled. (Why?!) More importantly, enabling virtualization fixed the problem.
