Re: [Xen-API] PCI passthrough - XCP vs XenServer



I'll just add that, depending on your hardware, you may have better
luck with PCI passthrough using XCP 1.6 rather than XenServer 6.2.
The reason for this is that XCP 1.6 relies on Xen 4.1, which, compared
to the Xen 4.2 used by XenServer 6.2, is more forgiving of errors
found in the IVRS tables of some motherboards, such as my Asus M5A99FX
Pro 2.0.
