PCI Passthrough - GPU - Matrox C-series
-
Interesting behavior I am seeing on a host. I moved a C420 from one host to another to free up some space for alternative GPUs in my 2U host.
After doing so, I cannot, for the life of me, get the C420 to show up in "GPUs" on this other host, for assignment. Of note, it normally shows up as a "AMD FirePro something", but, is not showing up at all now.
It shows up in lspci, I have verified it is not bound to a driver in dom0, it is on the list of "assignable devices" in xl, so, I'm at a bit of a loss. I have even tried assigning it manually to the VM through dom0 console, to no avail; although, it's possible my syntax is wrong, and, it's just not telling me.
I did follow the XenServer 7 PCI-passthrough guide just to be sure.
Any thoughts or suggestions would be helpful.
