Use aditional network card for vm
Hello all, My laptop have re0 and iwlwifi0 network cards with only re0 at use. vm-bhyve sets it to ifconfig bellow. I suspect that re0 being in promiscous mode, it will originate some network problems with backup programs like restic when reading too much files (restic check --read-data) and to fix this issue I turn off vm-bhyve network setting. Is it possible to have a card just to be in use by bhyve, e.g. usb external ethernet dongle or even laptop wifi card? Thanks, - re0: flags=1008943 metric 0 mtu 1500 options=8209b ether 00:2b:67:df:c6:73 inet 192.168.1.67 netmask 0xff00 broadcast 192.168.1.255 media: Ethernet autoselect (1000baseT ) status: active nd6 options=29 lo0: flags=1008049 metric 0 mtu 16384 options=680003 inet 127.0.0.1 netmask 0xff00 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 groups: lo nd6 options=21 vm-public: flags=1008843 metric 0 mtu 1500 options=0 ether 02:f4:ac:f8:d6:be id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: re0 flags=143 ifmaxaddr 0 port 1 priority 128 path cost 2 groups: bridge vm-switch viid-4c918@ nd6 options=9 - -- Nuno Teixeira FreeBSD Committer (ports)

(...) Ok I think I get it: - Use wifi card for laptop internet connection. - passtrhu re0 - edit vm/.config/system.info and remove bridge to re0.
