I have Linux dom0 machines that I'm quite happy with.

Now though I have some Sun hardware that really wants to run Solaris
(native hardware monitoring tools, ZFS, etc.)  I have OpenSolaris
2008.11 running happily on the hardware with a dom0 kernel, and I can
make it set up Solaris domU instances.  I *think* that I could make it
run Linux domU's if I had Linux ISO images with Xen kernels on them,
because that's what the Solaris domU setup tool expects; but so far I
don't have any such ISO images.

I do have (and can easily make) all sorts of domU system images, like
what one gets from jailtime.org.  That's easy.  What I can't figure out
is how to get the domU image into place for running on the Solaris host
system without following the expected pattern of "virt-install with an
ISO installer image".  So far as I can tell, xVM (the Solaris re-badge
of Xen) does things completely differently from Linux when it comes to
handling guest images, and the only docs I can find for it describe
their convenience tool, virt-install, not the mechanics of how
virt-install works its magic.
