Meanwhile, is there something like a "jass" profile (like we saw for
LDOMS) to make sure all the unneeded services are shut down and the
dom0 is firewalled strongly using the built-in ipfilter FW? So far I
disabled gdm, as that was obvious, then I enabled vtdaemon and vt2
which enabled a simple text login on the "graphical console" while the
real console is /dev/ttya. I generally also disable rpc/bind and the
host of other rpc services (unless they are needed for something?)
Open Solaris comes out of the box a lot "slimmer" than Solaris 10 or
NV, I am pretty impressed actually.

It really depends on what you mean by a minimal
server installation.
With the existing tool sets (xm, xend, and the
opensolaris pkg tools), we require python which
creates a good bit of bloat.
Also intrd brings in perl which is a little more
bloat.. And then the SDL support in qemu-dm brings
in some X libs.
And finally, the OpenSolaris packages need to be
refactored.. Right now there are too many cross
dependencies and packages which were combined which
cause a lot of unneeded stuff to be pulled in.
Unfortunately there is no way to tell pkg to
ignore dependencies.
But with all this, you still can create an image
which is much smaller than the default... I have a
script @
http://blogs.sun.com/mrj/resource/slim-guest-installer
that you can play with... You would have to modify
the package list to include the devices you need for
your H/W and the xen packages. This isn't supported
by Sun of course...
We are actively trying to make this better... But it's
going to take some time.
