ok, so in this case, the ip shouldn't work anymore. (dhcp listen on a different pool of ip on each bridge right? and dhcp need an ip in the range of the pool).

So we should deny changing bridge without changing ip.



(BTW, I we can force a renew of dhcp with qmp netlink off|on)

The VM config can change completely, for example use vmbr1 instead of vmbr0.
