I got VirtualBox 3.0.0 installed and one of the VMs is Windows 2008 Standard. My next step was to add the feature Hyper-V, but Windows 2008 tells me...
"Hyper-V cannot be installed. Server Manager has detected that the processor on this computer is not compatible with Hyper-V. To install thsi role, the processor must have a supported version of the hardware-assisted virtualization, and that feature must be turned on in the BIOS."
Code:
ntel(R) Core(TM)2 Duo CPU     E6850  @ 3.00GHz
Any ideas?

Hyper-V requires hardware virtualization support, which I imagine if it's already running in a virtual machine, it won't have access to. It's used for the host machine, not the guest. A quick glance at the wikipedia page seems to show it as Microsoft's clone of Xen.

It is possible for a guest to have access to hardware assisted virtualization, if the hypervisor arranges for the virtual hardware to provide it. Apparently, VirtualBox does not do so, at least by default. KVM has experimental support for nesting when using an AMD CPU. I am not aware of any Linux-hosted hypervisor which provides nesting on Intel CPUs.

Yeah Nested Pageing is available in VBox as well, but for AMD cpus only as well.

Moved from Kernel & Hardware to Unsupported Software.
VirtualBox 3 is not yet in Portage, thus unsupported.

I even tried it on VMware and it doesn't work either.
