I think the one-liner "Install Solaris Express build 44" should be augmented to note the requirement to allocate adequate disk space in the root partition for installing domU images since, if you do a default install (and why wouldn''t you), the default partition is not big enough. By the time you get there, a lot of time and effort has been wasted. Evidently one should always do a custom install to configure the file systems. It would suffice to put a note and a link to http://www.opensolaris.org/os/community/xen/How-To-8-15-06/Solaris-domU/ up front. Mick Jordan
