Hi,
I am trying to use PCI passthrough to pass the bge device to a guest
but I am doing something wrong. I have tried several combinations of
pptdevs like "2/0/0 2/0/1 2/0/2 2/0/3" but it always fails on 2/0/0.
Any ideas what I could try?
Did you read this: https://wiki.freebsd.org/bhyve/pci_passthru ?
After following those instructions, what is the output of pciconf -l -v
before and after enabling PCI passthru?
On the host and in the guest?

Then I start "bhyve ... -s 10,passthru,2/0/0 ..." and it spits:
"Unsupported MSI-X configuration: 2/0/0"
and quits.
This happens *only* with 2/0/0, that is the bge device. When I try to
passthrough this:
none6@pci0:3:0:0: class=0x028000 card=0xe042105b chip=0x472714e4 rev=0x01
hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM4313 802.11b/g/n Wireless LAN Controller'
class = network
it goes further, bhyve starts and the device is passed to the host but I
cannot use it from the VM. Actually my goal is to use the wifi adapter
from a VM. The bge device is just testing and I thought I should report
it/ask about it.
