[pve-devel] [PATCH 2/2] setup DHCP server at vm_start

[Alexandre DERUMIER]

>>And what if bridge or vlan changes? Above only works for ip changes. 

Do you mean, modify bridge configuration ? or change the vm network nic config ?

Libvirt do it like this, setup bridges/dhcp/ippool (restart dnsmasq) , and vm get ip through dhcp-config (without restart)

I don't have tried your patches yet, I need to look a little bit how ressources pool work.

And what if bridge or vlan changes? Above only works for ip changes.
