Subject Re: PCI-Passthrough with CloudStack (Improved)
Date Fri, 21 Jun 2013 00:35:27 GMT
Hi Paul,

I think that is more or less dependent on the hardware quirks. For my
case I only had to add intel_iommu=on to the kernel cmdline to get PCI
Passthrough working. An additional cmdline, pci=nocrs, was needed to
get SR-IOV mode of the Mellanox ConnectX-2 card working.

Best Regards,
Pawit
