Re: Network update disrupts network usage

The networkUpdate() method in libvirt source will recreate firewall rules if any DHCP hosts change. This is because the firewall rules differ when there is zero vs non-zero number of DHCP hosts present.

This could be optimized to only recreate when going from zero to non-zero or vica-verca.

Thanks for the information, Daniel. I have created https://gitlab.com/libvirt/libvirt/-/issues/76 to track this as a libvirt issue. Best regards, Joel
