Hello,

I would like to use Dom0 with PVH mode together with PCI passthrough in order 
to compare PVH and HVM in a real test scenario for early adoption of PVH. The 
minimum setup needed is to have the possibility to assign to a domain a PCI 
device that is passthrough.

Are there any patches in review or previous discussions on having PCI 
passthrough in Dom0 PVH?

Our internal tests showed promising results regarding performance (no PCI 
passthrough), but nonetheless as expected in this early stage of development a 
small decrease between 2.5 - 10%. Sacrificing performance for a boost in 
security offered by PVH should be a priority. For the final results to be 
conclusive and have a fair comparison, it is necessary to have a rough 
implementation of PCI passthrough (e.g. for a network device).

Any help towards this matter would be greatly appreciated.

Thanks,
Alex
