Hi everyone, I'm not sure it's VFIO or pure KVM issue on here.
Now we have one GPU server which contains few Tesla GPUs. Installed Fedora 28 and using VFIO to passthrough GPU into VM. Everything is OK, except one annoying things that we using PXE to install guest OS. But PXE can't get any DHCP IP if GPU mounted. We have to un-mount GPU first then re-mount once OS installation completed. For PXE, we use host bridge to connect host VLAN, then let PXE boot vnet going to connect that bridge. I'm not sure the root cause, probably from PCI setup inside VM. Does anyone have idea? Many thanks, Eddie.
