[picaditto]

Any help,
I get these error when try to setup one VM.

libvirt while performing "Start": "internal error: no IP address found for interface 'vmbr0'"

I don't understand the IP address system! Any help.

Hello,

the error means that there are no IP addresses on the bridge.
You need to assign at least one 1 IP address
