Topic : ubuntu 20.04 and virtnetwork failed after restart

Posted By: vahidssss on March 6, 2021, 4:22 am

Hi every one,
I have some wired issue with ubuntu 20.04,
I turned off the netplans and I use the legacy method.
I made a permanent bridge and it works.
but after restarting the virtnetwork service, the bridge will be gone and I have to restart the networking service to make it again.

Code

service virtnetwork status

● virtnetwork.service - Virtualizor Network Service

     Loaded: loaded (/etc/systemd/system/virtnetwork.service; enabled; vendor preset: enabled)

     Active: active (exited) since Sat 2021-03-06 05:06:30 CET; 8min ago

    Process: 12201 ExecStart=/etc/init.d/virtnetwork start (code=exited, status=0/SUCCESS)

Mar 06 05:06:30 hostname systemd[1]: Starting Virtualizor Network Service...

Mar 06 05:06:30 hostname virtnetwork[12202]: Error: No ip address found.

Mar 06 05:06:30 hostname systemd[1]: Started Virtualizor Network Service.

my /etc/network/interface looks like this ( I've changed the IPs):

Code

auto lo

iface lo inet loopback

auto viifbr0

iface viifbr0 inet static

address 192.168.1.10   

netmask 255.255.255.0   

gateway 192.168.1.1 

dns-nameservers 8.8.8.8

bridge_ports enp8s0

bridge_stp off

bridge_fd 0

bridge_maxwait 10

your right by switching to legacy method

but there is a little bug..

You must create file /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME so that virtnetwork can find the gateway.

no need to create bridge manual

To everyone else fist drop netplan and switch to legacy network method
just use https://tweenpath.net/ubuntu-18-04-disable-netplan-switch-networking-etc-network-interfaces/

Also ipv6 works fine with hetzner, Just install it in the correct way
