Hello
Beside the Qemu project, … what are the QNX guys thinking about a Xen port to QNX 6.x, - dom0 and domU. There are a lot
 of Xen porting activities for several OSes around the world today, e.g. OpenSolaris, XEN port of the XNU kernel used by
 Mac OS X and OpenDarwin, FreeBSD, Linux, NetBSD etc.

The dtrace was ported successfully, perhaps a Xen port is possible, too :-).
Thanks
