Request for help with pci passthrough with VTd on Debian Jessie
Hi,
I am having great difficulties in getting pci passthrough with VTd to
work, surely I am doing something stupid but I cannot see what.
"tangram" (https://www.blogger.com/profile/06588030231546523539) has
been a huge help, but despite his efforts I am still stuck.
Hardware: Intel S3200SHV motherboard

so it all looks OK so far, but:
xm pci-list-assignable-devices
and nothing shows.
If anyone would point out my obvious mistake(s) I would be extremely
grateful.
