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 Dale On Tue, Jul 28, 2009 at 5:31 PM, Dmitry Nedospasov <[email protected]>wrote: > On Jul 28, 2009, at 06:12 , Dale Stirling wrote: > >> Xen will work for full virtulisation and run Backtrack (haven't tested). >> > > I think this has been a bit understated in the current discussion, namely > the main advantage of Xen, the paravirtualization.
