I got the pulse-eight adaptor working by adding the address manually to the xml for the VM. <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x2548'/> <product id='0x1002'/> <address bus='7' device='5'/> </source> <alias name='hostdev1'/> </hostdev> The above is the code specific to my installation but it might be of some use.

I have had some success that I thought you might be interested in; I have successfully passed through the on board graphics and HDMI audio to an OpenELEC VM! Video playback including 1080p blu-ray rip play back with no problems! I am having an issue with DTS-HD and TrueHD passthrough but I suspect it is an OpenELEC or driver issue rather than a VM specific one. Check out your system log and look for anything similar to this (what I found in my log!): Oct 3 17:32:30 Tower kernel: [Firmware Bug]: AMD-Vi: IOAPIC[5] not in IVRS table Oct 3 17:32:30 Tower kernel: [Firmware Bug]: AMD-Vi: No southbridge IOAPIC found Oct 3 17:32:30 Tower kernel: AMD-Vi: Disabling interrupt remapping This alerted me to the fact that all was not well with my AMD-Vi. I did some googling and came across this article: http://ubuntuforums.org/showthread.php?t=2254677 Using the information from the above article I made some amendments to my syslinux.cfg which now looks like this: default /syslinux/menu.c32 menu title Lime Technology prompt 0 timeout 50 label unRAID OS kernel /bzimage append initrd=/bzroot label KVM/unRAID OS (AMD) menu default kernel /bzimage append amd_iommu=on ivrs_ioapic[5]=00:14.0 initrd=/bzroot label KVM/unRAID OS (AMD Test) kernel /bzimage append iommu=pt iommu=1 ivrs_ioapic[5]=00:14.0 initrd=/bzroot label KVM/unRAID OS (Intel) kernel /bzimage append intel_iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1 pcie_acs_override=downstream initrd=/bzroot label unRAID OS Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot unraidsafemode label Memtest86+ kernel /memtest label Xen/unRAID OS kernel /syslinux/mboot.c32 append /xen --- /bzimage --- /bzroot label Xen/unRAID OS Safe Mode (no plugins) kernel /syslinux/mboot.c32 append /xen --- /bzimage --- /bzroot unraidsafemode Using the "AMD Test" menu selection on boot I am able to run my VMs without unsafe interrupts and I am also able to passthrough the on board graphics!! Hope this helps anyone who is looking for a solution!

I have done some experiments this morning with a Windows 7 VM I set up. I have been able to pass through the HD6450 to it and display the output of the VM on my TV but when the APU is selected I get no output, just a black screen. I tried changing the primary graphics adapter in the BIOS but this had no effect on the result.

I am using an ASRock FM2A88M Extreme 4+ with an A8-6500T, I also have an ASUS HD6450 1GB graphics card which I am using to virtualise Kodi. I was using Citrix Xenserver 6.2 and virtualising UNRAID 5, Ubuntu and Windows 7 (for Kodi). As off this week I have installed UNRAID 6.1.2 and I am using it to virtualise OpenELEC via the HD6450 and am passing through a keyboard/mouse to it and a Pulse-Eight USB-CEC adapter. It is all working great, I just had to add some kernel arguments I found on the forum to get the IOMMU working. The MoBo has 8 SATA3 ports natively which was also a big selling point to me.
