Description

host VirtualBox 6.1.6 r137129 (on windows 8 x64), guest Ubuntu 18.04 LTS HWE kernel 5.3.0-51-104generic #44~18.04.2-Ubuntu SMP Thu Apr 23 14:27:18 UTC 2020 x86_64 GNU/Linux, host have 1 ethernet interface directly connected to standalone d-link router with cable, guest have 3 nic's, 1 nat, 2 internal network, 3 brdiged-adapter.

problem with manage bridge or vlan on guest, if i add manualy interface to bridge or configure vlan, after execute command - guest(ubuntu) freeze, do manual reboot.. example:

#bridge modprobe bridge brctl addbr br0 #(all is ok) brctl addif br0 bond0 #(all is ok) brctl addif enp0s3 #(freeze) (tests enp0s3 as NAT, enp0s8 as Lan and enp0s9 as Bridged-adapter)

doesn't matter enp0s3/8/9 up or down before add to bridge, with IP address or without it..

#vlan apt install vlan modprobe 8021q vconfig add enp0s3 100 added VLAN with VID == 100 to IF -:enp0s3:- (freeze)

maybe this a problem with my ubuntu in wrong network configuration or with kernel, I ask your help to make it all work :)
