MiXen currently only implements a ramdisk.
This ramdisk can either be empty
or be preloaded with some image file.
There are some exmample configuration files in the
configuration provides the
NetBSD installation CD
image for some client.
configuration emulates an empty ramdisk
with about 1GB of free space.
When both of those are running,
configuration will use those two ramdisks
and allow the installation of NetBSD from the
emulated CD onto the empty disk image.
On initial boot, be sure to tell NetBSD to use
xbd1 as its root filesystem.
you can reboot the virtual machine,
and it will come up from the ramdisk image.
