After creating the vGPU, if required by the host driver, all the other type ids would disappear from "virsh nodedev-dumpxml pci_0000_86_00_0" too.
Not wanting to make assumptions, but this reads as if I create one type 11 vGPU, then I can create no others on the host. Maybe I'm reading it wrong - it's been a long week.
Correct, at least for NVIDIA.
OK, but so what am I missing vis-a-vis the groups conversation? Sounds like multiple vGPU's are being combined, but if only one can be created. I think this is where I got confused while reading...
PCI devices have the "managed='yes|no'" attribute as well. That's what determines whether the device is to be detached from the host or not. That's been something very painful to manage for vfio and well libvirt!
mdevs do not exist on the host (they do not have a driver on the host because they are not PCI devices) so they do need any management. At least I hope that's good news. :)
Laine was more eloquent than I on this... John
