On Debian hosts I run VirtualBox VM mainly to run WinX software. Some of these VM shall join AD and as such need fixed IP and shall be reachable from the LAN, i.e. NAT is no option.
I considered bridged networking to do the trick, but it turned out that the VM uses the IP of the host instead of asking my DHCP server. (Or probably it does but uses the MAC of the host's NIC, instead of the MAC assigned for the machine. Since booting the machine with improper network is painfully slow, I try to keep experiments well targetted.)
What I would like is that the VM appears as it would be plugged into a switch with the host. Is this too exotic, or is there a canonical way to achieve this?
