...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 cap...

Hi, I am trying to make the vt-d and pci pass-through work and I have some problems. I just try to give a NIC to an HVM guest. When I create the vm the hypervisor goes to an infinite loop, it displays in loop the message enclosed (console_on_xm_create). I use xen x86_64, debian etch dom0 with linux-2.6.18.8-xen 32. The hvm guest is a debian etch 64. Cheers, -- Jean Guyader

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

Hello everyone, Reposting with after having applied the (minor) fixes suggested by Wei and Jan. Allen, if you can tell us what you think about this, or suggest someone else to ask some feedback to, if you''re no longer involved with VT-d, that would be great! :-) -- As already discussed here [1], dealing with IOMMU faults in interrupt context may cause nasty things to happen, up to
