Hi Michael,
After you change your BIOS's VT-d setting from Disabled to Enabled (or from Enabled to Disabled), can you try power cycle your host (unplug the power cord and wait for some time)?
If this works, it would be a BIOS issue.

 

Thanks,
-- Dexuan

 

Thanks for the prompt reply Dexuan,

I disabled the VT-D setting in bios and xen boots fine after a cold powercycle

So it appears to be a bios issue.

 

For reference here is the xen boot output with VT-D disabled.
