i use Virtual Box and want to try XEN in it.
All is possible but i cannot not install a self made OS.
"HVM" Problem.

Normally Virtual Box use VT-technologie but i don't now XEN can use them still at time? Virtual in Virtual ist this possible with VB or something els VirtualMachine-Software?

Great day and fell fine

Xen will probably work inside of VirtualBox but I doubt that you will be able to get a HVM guest to work. Most virtualization technologies do not pass thru the VT or SVM capabilities of the processor to the guest OS (in your case, your Xen installation). So as far as Xen knows, it is running on a machine that does not support VT or SVM. You can check this by doing `cat /proc/cpuinfo` and looking for vmx in the flags area. You should be able to install PV guests though. If you are wanting to just experiment with Xen, doing it in VirtualBox is alright. But I would not recommend it for a regular Xen installation.
Hope that answers your question.
