Hi,
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?
This sort of things should only be done for testing purposes and just to
check whether nesting actually works or not and that is the end of life.
These sort of things doesn't really yield any values. Two days before,
I had a test running xen dom0 as a vmware guest and running domu in
that dom0. Paravirtualized guest can start successfully. The end result
was that, performance was worst than sluggish that I could ever imagine,
random crashes, random hangup and etc...
None of the virtualization technology is designed for nesting, so no one
can get any value out of it.

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.
