Bahaha! I feel like a wizard! This is so awesome, thank you! GPU passthrough is working! You guys are geniuses!

You need to go to your Unraid top menu, go to Settings, then choose Network Settings. You then need to turn Setup Bridge to On and give the bridge name "br0".

Ok, my issue was my hard drive config. I've worked that out, and the VM starts, and I can VNC to it. But then when I go to add the qemu commandline stuff, it'll say it saved successfully, but when I go back in, the qemu commandline section is gone. Here's my most recent xml: <domain type='kvm'> <name>WMC8.1</name> <uuid>554cbf6b-aa75-4044-b1b3-c1005bea6064</uuid> <memory unit='KiB'>7813120</memory> <currentMemory unit='KiB'>7812500</currentMemory> <memoryBacking> <nosharepages/> <locked/> </memoryBacking> <vcpu placement='static'>4</vcpu> <resource> <partition>/machine</partition> </resource> <os> <type arch='x86_64' machine='pc-q35-2.1'>hvm</type> <boot dev='hd'/> <bootmenu enable='no'/> </os> <features> <acpi/> <apic eoi='on'/> </features> <cpu mode='host-passthrough'> <topology sockets='1' cores='4' threads='1'/> </cpu> <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup'/> <timer name='pit' tickpolicy='delay'/> <timer name='hpet' present='yes'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/mnt/user/VM/WindowsMediaCenter/WindowsMediaCenter.qcow2'/> <target dev='vdc' bus='sata'/> <address type='drive' controller='0' bus='0' target='0' unit='2'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/cache/iso/virtio-win-0.1-81.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> <controller type='sata' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x1f' function='0x2'/> </controller> <controller type='pci' index='0' model='pcie-root'/> <controller type='pci' index='1' model='dmi-to-pci-bridge'> <address type='pci' domain='0x0000' bus='0x00' slot='0x1e' function='0x0'/> </controller> <controller type='pci' index='2' model='pci-bridge'> <address type='pci' domain='0x0000' bus='0x01' slot='0x01' function='0x0'/> </controller> <controller type='ide' index='0'/> <interface type='bridge'> <mac address='52:54:00:06:62:4f'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/> </interface> <input type='mouse' bus='ps2'/> <input type='keyboard' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' websocket='-1' listen='0.0.0.0'> <listen type='address' address='0.0.0.0'/> </graphics> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x02' slot='0x06' function='0x0'/> </memballoon> </devices> </domain> Here's what I've been adding between the <devices> and </domain> that doesn't get saved in the VM Manager plugin by dmacias.

Instead of filling useful and informative threads with my questions, I figured I'll just make one place for it. So I believe I am one silly mistake away from having a Windows 8.1 WMC box up and running with GPU passthrough, but I can't get it to start. Here's the xml: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>WMC8.1</name> <uuid>554cbf6b-aa75-4044-b1b3-c1005bea6064</uuid> <memory unit='KiB'>8388608</memory> <currentMemory unit='KiB'>8388608</currentMemory> <memoryBacking> <nosharepages/> <locked/> </memoryBacking> <vcpu placement='static'>4</vcpu> <os> <type arch='x86_64' machine='pc-q35-2.1'>hvm</type> <boot dev='hd'/> <bootmenu enable='no'/> </os> <features> <acpi/> <apic eoi='on'/> </features> <cpu mode='host-passthrough'> <topology sockets='1' cores='4' threads='1'/> </cpu> <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup'/> <timer name='pit' tickpolicy='delay'/> <timer name='hpet' present='yes'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none' io='native'/> <source file='/mnt/user/VM/WindowsMediaCenter/WindowsMediaCenter.qcow2'/> <target dev='vdc' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x04' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/cache/iso/virtio-win-0.1-81.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> <controller type='sata' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x1f' function='0x2'/> </controller> <controller type='pci' index='0' model='pcie-root'/> <controller type='pci' index='1' model='dmi-to-pci-bridge'> <address type='pci' domain='0x0000' bus='0x00' slot='0x1e' function='0x0'/> </controller> <controller type='pci' index='2' model='pci-bridge'> <address type='pci' domain='0x0000' bus='0x01' slot='0x01' function='0x0'/> </controller> <controller type='ide' index='0'/> <interface type='bridge'> <mac address='52:54:00:43:1e:7b'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/> </interface> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x02' slot='0x06' function='0x0'/> </memballoon> </devices> <qemu:commandline> <qemu:arg value='-device'/> <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1'/> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on'/> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=01:00.1,bus=root.1,addr=00.1'/> </qemu:commandline> </domain> When I go to start the machine using dmcias's new plugin he released today, I get the following: Error while starting domain: internal error: process exited while connecting to monitor: I have the storage for the qcow and virtio iso in the storages.

Haha, oh man. Thanks! Would you mind fixing it in your opening post? I always copied from that and didn't proof read it. Thanks for all of your work on this. This is amazing!

Couldn't a workaround for this be a Docker container? Or does the base Ubuntu 14.04 not have the gui installed?

Gah! I was getting the error at the WebVirtMan, so I didn't continue to install the following plugin. Thanks! All good now!

I'm stuck here. Did you figure out how to get past this part? I'm on 6b10a. This is my first unraid install, but I've created a cache drive, an array, setup Plex Media Server on docker. I mounted and copied files from my NTFS drives to the array. I converted my vdi to qcow2, and created the xml file, but can't seem to get virsh to work. Everything I find online is talking about where code was compiled, of which I haven't messed with on this setup, so it should be stock. Thanks for any help.
