Configuring BIND to use VM's DNS for specific domain

view story

http://serverfault.com – I work on a project for which I use an Ubuntu server vm on an Ubuntu host. The VM runs all the services / webapps through haproxy and nginx and serves it on the domain (xyz.com). I manually modify my resolv.conf to use the VMs IP address as the nameserver and I can run my app on the host browser. The problem is I am modifying an auto-generated file (resolv.conf) and I need to do it each time. Is there a smart way to say: -- are you accessing xyz.com? -- if yes use VM's DNS server, else use the hosts (HowTos)
