blacklist radeon

blacklist nvidia
// why does not add r8169? since i use server network(Internal&External), so i think if i add r8169 in blacklist my nic's module(A,B nic) dose not work.(probably)

Hi, I have 2 ports nic(1 pcie x1 card, 2 ports).
I want use UTM(Untangle firewall). So i boot vm sever with pci device(pass-throughed, C.0&C.1)
My proxmox server was stop. (I think, that was Kernel panic.)
If you have any idea, write feel free!



(My english not well, because i am korean. I apologise to you.)

Did it stop after you tried to start the VM with the PCI passthrough?
Any information in the logs or on an attached screen?
