August 5, 20205 yr Hi - had the same problem.  I did solve it with this command in ssh: Quote virsh net-start default  So - reboot isn't neccessary.  Â

January 29, 20215 yr Hello i have the same problem with my vms. Sadly a reboot does not fix the problem. Also by running the command "virsh net-start default" came an error.  i hope someone can help me. Thank you!
January 29, 20215 yr From your screenshot I see that you have indeed NO 'br0' network. That's the reason why the VM fails. WHY you don't have no 'br0' is the other question... Â my network looks like this:Â Â
January 29, 20215 yr I also dont know why "br0" is not there anymore. Hmmm and when i try to add it manually it does not work sadly.
January 29, 20215 yr hmm... you could try to disable "bonding" by setting "enable bonding" to "no" - because you only have one bonding-member (eth0) - so there is no benefit in enable bonding?! Â i just saw it - you don't have the "bridging members" - certainly because of enabled "bonding" ... i really would try that! Â ...maybe this makes a difference?! and after that a reboot...
