Hello,
I have been working sometime now on getting a HVM accepting a PCI card from
the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO
motherboard (rel 0803) which has the VT-D option in the bios. I want to pass
a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first
trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in xm
dmesg, i upgraded the system to run XEN 3.3 which ended up having errors
regarding "(XEN) [VT-D]iommu.c:775: iommu_page_fault: iommu->reg =
ffff828bfff57000" in xm dmesg
This happens both with and without pciback.hide in grub commandline. If I
use "pci [xx.xx.xx] in my HVM conf and boot the HVM the host crashes and I
have to hard reset the system. It will happen both for a PCI network card as
well as the capture card.
Is it possible to overcome the iommu_page_fault error in 3.3.0?
If not and I have to go to xen-unstable can someone provide me with a link
how to build xen-unstable. I am keen to learn but only have about 2 yrs of
experience.
Many thankx
Han
