Hello Allan,
I think it should be possible without too many issues. We have a
whitepaper on the wiki to describe the basics of Xen on ARM and its
architecture:

http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions_whitepaper

Also refer to the main Xen on ARM wiki page:

http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions

One thing to keep in mind though is that Xen on ARM requires
virtualization extensions, so Cortex A7 or Cortex A15 or newer
processors. As far as I can tell I.mx6Q is still based on A9: too old to
support virtualization extensions.  You might want to get a Cubietrack,
for example.

I'll be at the Xen Developer Summit too, I look forward to talking to
you.

Cheers,

Stefano
