Thanks, I'm aware of jailtime, and one of their images would be just
fine.  The trouble I'm having isn't coming up with a domU image, it's
getting the Solaris virt-install utility to use it.  I figure there's
something I'm just not picking up on in the man page, but here's an
example of what I've tried so far:


  $ sudo virt-install --nographics --name foo --paravirt --ram 1011 --file 
/dev/zvol/dsk/mtank/foo --location /export/home/mjinks/gentoo.2008-0.img

(The .img file is a downloaded 32-bit Gentoo domU from jailtime.org.)

virt-install prompts me for the size of the disk image to create, since
"foo" doesn't exist yet, then:

  Starting install...
  hsfs mount: /export/home/mjinks/gentoo.2008-0.img is not an hsfs file
  system.
  umount: warning: /var/tmp/virtinstmnt.7bQr8T not in mnttab
  umount: /var/tmp/virtinstmnt.7bQr8T not mounted
  Invalid install location: Mounting location
  /export/home/mjinks/gentoo.2008-0.img failed
  Domain installation may not have been
   successful.  If it was, you can restart your domain
   by running 'virsh start foo'; otherwise, please
   restart your installation.
  Sat, 10 Jan 2009 00:12:14 ERROR    Invalid install location: Mounting
  location /export/home/mjinks/gentoo.2008-0.img failed
  Traceback (most recent call last):
  <snip traceback output>


That's why I got the impression that virt-install really wants to boot
the system from an ISO disk image.  If there's a way to point it at a
non-ISO disk image to boot from, I'm not finding it in the manpage.
