They are created and destroyed dynamically when bhyve clients are run. (In reply to Lexi Winter from comment #5) VirtualBox uses special kernel drivers to attach to an interface in bridged mode. As far as I can see in the sources (emulators/virtualbox-ose-kmod), it uses netgraph and bpf. Maybe one or both of these are missing from if_bridg= e. Disregarding the VirtualBox setup, there is still the problem that there are performance problems under load - issue 3. from the list at the end of my original message. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
