Yes you could run Backtrack in para virtulisation and you get near bare
metal performance, but you will need to find/build a xen-kernel for the DomU
that has all of the modules/drivers that back track requires.

I run Xen on RHEL5 and Centos servers at home and in production with
paravirtual DomU's with out issue, but these are built from the Centos/RHEL
ISO images. The GTK Virtual Machine Manager works really well for building
new DomU's
