Add an option for passing Solaris JumpStart information. For HVM
guests, this means a floppy image (!).

I think its better not to add this OS specific option. You can
apass the Jumpstart floppy image using the recently added generic
--disk option

--disk path=/path/to/image,device=floppy

Daniel

I don't think it's OS specific. I set up kickstart a while back and it
involved a lot of magic boot options with -x, why not make it easy?

And for NFS JumpStart?

I wouldn't be opposed to adding support for this, provided it is in a
sufficiently generalized manner that we could reuse the command line
and API to add support for specifying a kickstart, autoyast, etc.
Something like:

--auto-install type=autocf,media=http://example.com/foo.img

The data should also be associated with the Installer class, rather
than the Guest class.

I just don't see what value this gives over the existing

--extra-args media=http://example.com/foo.img

or whatever the OS wants.

You're forgetting the specification of the networking setup needed in
many cases. I'm supposed to remember the exact command lines needed for
each OS's variant of automated install? Have you seen what old Solaris's
cmdline looks like?

virt-install should be fall-over easy to use.
