Hi,

Is vtd / pci passthru broken in 3.3? On my Supermicro x7dwa-n system I
was able to get pci passthru working with 3.2.1, but with 3.3 the xen
dmesg states that it is disabled:

(XEN) I/O virtualisation disabled

I used the same argument to enable vtd as I did with 3.2.1, is this correct:

(XEN) Command line: vtd=1 com1=115200,8n1 console=vga,com1 noirqbalance

Thanks
Andy
