We run Junos in vm's under lots of different circumstances. An etc/rc.d/vmguest is used to tailor the vm to the environment it finds itself in at firstboot. A raft of etc/rc.conf.d/vmguest.* help tailor the basic logic to different platforms and vmhost environments. It generally does nothing at subsequent boots. We handle dynamic configuration, by providing a separate device to be used for swap, var etc. Dynamically sized swap is very handy.
