[pve-devel] internal dhcp server, where to put dhcp configuration ?

Yes, indeed. (the wiki use eth0 instead vmbr0, and vmbr0 instead vmbr1, but indeed it should work).

Also I think we don't need "post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp", 
if vms nic are on bridges without plugged eth0, the arp protocol can't be routed.

(Note that I don't known if the wiki article talk about openvz or qemu network, don't known if both can work in the same way)




I have found a very good descriptive mail about libvirt networking implementation here:
