Description

Kind of related to #533. I use firewalld, which configures the traffic filtering rules via nftables, rather than iptables. Not stopping firewalld or forgetting to move the mpqemubr* interface to the right zone results in problems launching the instances. AFAIK libvirt integrates with firewalld by setting up a separate zone for the bridge interface.

Research direction
Investigate how libvirt integrates with firewalld by setting up separate zones for bridge interfaces. Examine the current networking code in Multipass, particularly the bridge setup logic. Determine if firewalld dynamic rules or direct nftables configuration is needed. Consider adding a configuration option for firewalld zone.
