RE: [Xen-devel] Re: about sr-iov

["Zhuo Song" <alfred.z.song@xxxxxxxxx>]

Brian,

Thanks for your information and I'd like to give them a call. 
But I also concern that why it still failed when I tried to make os kernel
do allocation for the pci buses. 
It seems very interesting if it could be a work around for the BIOS with no
sr-iov enabled.

Best Regards

It sounds like the HP system does have VT-d enabled or it does not support
SR-
IOV in the BIOS. I would check the HP support site or give them a call.

Take a look at either of these sites below for more information on SR-IOV.
