I have been meaning to do a blog entry on how to do
this but haven't found the time yet...
Here's a quick way to build a minimal domU which
can also be used for an embedded dom0.
I have a dom0 which I run off of a ram disk booted
from a USB flash and then can start multiple domUs
using the same ramdisk used to boot dom0.
I'll just cover how to build the domU and then
follow up how to build the ramdisk and put it
on a USB flash in a later e-mail.
Setup your domU disk, newfs it, and mount it.
In this example I'm assuming you mounted it
under /mnt.
: alpha[1]#; dd if=/dev/zero of=./disk.img bs=1024k count=512
: alpha[1]#; lofiadm -a `pwd`/disk.img
: alpha[1]#; newfs /dev/rlofi/1
: alpha[1]#; mount -F ufs /dev/lofi/1 /mnt
then run the script below, unmount/lofiadm -d your
disk, then boot your domU and configure it how you want.
You may want to customize the packages to include any disk
adapter/NIC drivers you need, etc..
I'm using the following py file to boot it.
Make sure you umount /mnt and lofiadm -d
first ;-)
: alpha[1]#; cat embedded-disk.py
name = "embedded-disk"
vcpus = 1
memory = "512"
root = "/dev/dsk/c0d0s0"
disk = ['file:/export/guests/embedded/disk.img,0,w']
vif = ['']
This is a script that I've been hacking on.
suggestions/improvements welcome. :-)
Someday I'd like it to be command line based but
don't have time to do that right now.
You need to modify the ROOTDIR, PROD, and PROD_OVERRIDE
paths below. Also customize any packages you want/don't
want.
I have a SMF service which I commented in my setup
which brings up DHCP on all NICs reported by dladm.
Probably better if you use NWAM. But I can send those
out if someone is really interested.
