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.
