Hi All,

I'd posted earlier on caiman-discuss@ some questions about our proposed
solution to AI support for xVM domU guests, and was wondering if I could
get you guys to take a peek at the webrev?

http://cr.opensolaris.org/~timf/6808205-virt-install-ai/webrev/

Specifically for xVM, this breaks down to:

 * HVM guests - no change, we have --pxe boot there
 * PV guests - we grab the boot_archive and kernel from the
   install_server, boot the microroot (with -B install_server set
   to the same location we pulled the boot_archive and kernel from)

Both types of guest need defect 6850 fixed before they'll work.

Specifically though, I'm looking for an opinion (and perhaps a bit of a
crystal ball?) as to whether you guys are planning a minimal bootable
LiveCD that's capable of kicking off an AI install?


Trying to predict what you might do in that case, I have code at the
moment that checks to see if the PV guest was passed a non-http/https
location as its installation media, in which case it doesn't pass the
"install_media=" line to the AI client, the thinking being that the
client shouldn't have to download *.zlib files if they're available
locally.

Does this make sense or should I still be passing that boot option
regardless?

As for an exact timeline for my changes, I'm not sure when this stuff is
planned to go back, I just wanted to be in a position to say whether
it's ready or not, and would really value your opinions!

        cheers,
                        tim
