NVME M.2 Passthrough
So I got my gaming machine up and running on a Ryzen system with a gpu passthrough and everything going good. Last thing I want to do is pass through an NVME drive to the machine but I keep getting this error
internal error: qemu unexpectedly closed the monitor: 2018-06-04T23:48:57.302131Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,id=hostdev2,bus=pci.0,addr=0x8: vfio error: 0000:01:00.0: failed to add PCI capability 0x11[0x50]@0xb0: table & pba overlap, or they don't fit in BARs
Firmware crap (often seen in nvme controllers, but also other devices), not unraid fault, you need to relocate the bar in the xml.
Depending on the libvirt/qemu versions, one of the following 3 solutions apply; assign an alias to the nvme controller, then add the custom arg
I think for unraid <= 6.10RC2:
...
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
