No. VirtualBox and xVM Server are different hypervisor types and
significantly different products. For one thing, xVM Server is tightly
integrated with the host operating system while VirtualBox is a portable
application.
Technically, the problem is that hardware virtualization can't be
shared, there can be only one 'owner' (as Ed said).
It might be possible to use the software virtualization mode of VBox
on a xVM Server system, although I don't think that's a supported setup.
Virtualization is difficult enough when one hypervisor controls the
system, and having two hypervisors running at the same time is a can of
worms that I don't think anyone is keen on opening.
Theoretically it *might* be possible for VirtualBox and xVM server to
cooperate, but that's really solving the wrong problem - there should be
no need to run both at the same time.
