I am experiencing the exact same issue.
If you don't need to use networkd, I think your issue can be solved by adding this file /etc/netplan/01-network-manager-all.yaml
with these contents to your netplan directory.
network:
version: 2
renderer: NetworkManager
After you have added this file make sure there aren't any other files in that directory that will take precedent, then use the command sudo netplan apply
. You may need to do a reboot for these changes to take effect in the settings tab though.
I recently updated my netplan.yaml file to use networkd
instead of NetworkManager
. Since doing this my VMs are now discoverable through my network bridge but my VNC client stopped working. In the sharing page under screen sharing, I no longer have the ability to turn on screen sharing as there are no networks to be found. This of course is false as I am connected to the internet through br-mmrk1
Switching the renderer back to NetworkManager
allows network sharing to be enabled again but the network itself doesn't work and I can't connect to my VNC client.
If I remove the network bridges and simply use the default NetworkManager everything works, except for my VMs of course.
Currently my work around to manage my VMs, which you may find useful if you are using your machine for Vms as well, is to manage the VMs remotely using virtual manger on another computer.
Here is the video guide for that --> https://www.youtube.com/watch?v=_SiJSz_2NaY
Here is my /etc/netplan/01-networkd.yaml
file where I have to use networkd
. I would be interested to see your netplan file to compare.
