[Xen-devel] [xen 3.5-unstable] passthrough of pci USB card fails

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi,

I'm trying to passthrough a pci USB card to a DomU (HVM).
Although pciback seems to seize the device with all functions as seen in
the dmesg output, they don't appear using "xm pci-list-assignable-devices".

When trying to passthrough to a HVM (with VT-D enabled) it stops creating
the domain and complains about:
VmError: pci: 0000:01:00.2: non-page-aligned MMIO BAR found.

From what I read, booting the xen hypervisor with "reassigndev=" should
solve the non-page-aligned issues, but apparently it doesn't in this case.
Also added them to xend-pci-persmissive.

Is there another boot-option/way to reassign the device ?

Regards,

Sander
