Patch to make bhyve pci passthru work inside a jail
on FreeBSD 12.2-RELEASE is possible to run bhyve inside a jail, but testing
passthru revealed that this not work inside a jail.
The problem is that the jail needs r/w access to the following devices:
* /dev/mem
* /dev/io
* /dev/pci
/dev/pci is not a problem with a securelevel < 0. But the rest needs a patch.
I have attached a rough patch to make bhyve pci passthrough work inside a
jail,I also have attached jail.conf and devfs.rules used for testing.
This was tested in jail using vnet.
