Maintaining forked trees is too much hassle. Hopefully the two architectures can coexist, with the appropriate one being selected at compile time (eg,. by building Xen with or without 'nodev=y'). > I have enjoyed watching the evolution... > > If I can help in debugging, or testing, I would be glad to volunteer. > > Am I right in saying, that at the moment, I can't launch a non-0 guest? > (I am using the demo CD for non-0 domains, and have been booting each > from the CD.

If you did not build Xen with 'nodev=y', and you did not specifically build real device drivers into Xenolinux, then everything should work as it always has done. The CD should be accessible from other domains, provided that appropriate VBD parameters are specified when the domain is created. > Is there any other structure I can use today to boot a non-0 guest with > today's 1.3? You can still build Xen and Xenolinux as you normally would. Out of the box all the new IO world is disabled. You have to explicitly select it at build time by compiling Xen with 'nodev=y make' and configuring Xenolinux to allow physical device access (it's a kernel config parameter). Once the new IO stuff is complete, the old architceture will be removed and devices-in-domains will become the default build configuration. -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
