[SOLVED] Network bridge for KVM guests no longer working

[mgnut57]

After a long time of not starting a VM guest on my machine, I fired one up today.

However, I think that the network bridge on the host is not working. The client doesn't have any network connectivity. I tried setting a static IP address on the guest and this did not improve things.

What might have changed since last March to cause this?

I think that I have the solution. Docker sets its own iptables rules and these were blocking the bridge forwarding.

Hi mgnut57

I may have run into a similar issue. Booting my system without docker resulted in my QEMU VM having network access through the bridge again.

Did you manage to find a working solution that also starts docker automatically?

Thanks and regards
