That package is a meta-package for the xen_server package. 'patterns' on
OpenSuse are just functional collections of packages.

It has nothing to do with commercial Xen.

I know this machine was originally installed with at least opensuse
11.4. I upgraded it from 11.4 ==> 12.1.  I don't know if it was
originally installed on 11.4, or sommthing even earlier and then

Short of reinstalling the machine from scratch, I don't know to clean
things up.  It sounds like it's more that just deleting the xenstore
database somehow.

I found this post from a year ago by an OpenSuse Xen developer -


"Xen 4.1.0 (due February 2011) will be the first release in which thenew
xl/libxl (aka libxenlight [1]) toolstack will be the default,preferred
tool set. Although still included in the release, the legacyxm/xend
toolstack will be disabled and in process of deprecation."

That was for 4.1.0. The current version is 4.1.2.  The post reads then
like we already should be using xl in OpenSuse.  Looks like the author
posts on this list too.  I'll CC him directly on just this email. Maybe
he can participate here a bit and has some ideas.
