Re: [Xen-users] XCP: PCI pass through Howto

[James Troup <james@xxxxxxxxxxxxxxxxx>]

Hi Dave,
is there any more to it than that?

Do I have to hide the device from, dom0.

I tried as you suggested but I cannot see the device in domU

Am I missing something?

Does this rely on VT-d ?
Does it only apply to HVM?

Thanks,
James

Hi,

 

The only documentation is currently in the code L

 

Try a command like:

 

xe vm-param-set uuid=<uuid> other-config:pci=0/0000:00:00:0

 

and then start the VM. (Change that PCI bus path to be the one you actually want to use)

 

http://xenbits.xen.org/xapi/xen-api.hg?file/a8decf9d3bee/ocaml/xapi/vmops.ml (line 483, pcidevs_of_vm)

 

Cheers,

Dave

Hi,
where can I find out about the experimental PCI pass-through in XCP?

I do not seem to be able to find any documentation.

Thanks.
