Problem with VT-x in Virtual Machine

[s.graf]

My configuration is:

HARDWARE : SERVER IBM with 2 x Intel(R) Xeon(R) esa CPU E5645 @ 2.40GHz - 36 GB ram
http://ark.intel.com/products/48768...-E5645-(12M-Cache-2_40-GHz-5_86-GTs-Intel-QPI)

SOFTWARE : PROXMOX Version 2.1-1/f9b0f63a

I've 3 Virtual Machine runnig without problem.


I need to create a new virtual machine A (IBM-> Proxmox-> Win7) and install another virtualization software to start up another virtual machine B (IBM-> Proxmox-> Win7-> VirtualBox/VMWare-> Win7).
I tried both VMware or VirtualBox but I always get an error like: the VT-x hardware acceleration is not available on the system
The problem seems to be that in the virtual machine A (IBM-> Proxmox-> Win7) is not enabled the 'VT-x hardware acceleration'.

Any suggestions?

P.S. Sorry for my english!

Hi,
to use hardware-virtualization inside a VM nested virtualization is necessary. First only amd-cpus support that, but intel must do a lot work (because of they virtualization) and support this later as well.

Search for "nested virtualization" how to switch on this feature.
