Just adding to the list of happy customers. I run about 70-80
SUSE domains on openSUSE 10.2, similarly hosting various development, QA
testing, demonstration and both critical and non-critical production
servers. Only problems we've had so far have been some hardware issues
totally non-Xen related and some problems with our own software, again
not Xen related.

I have my own scripts for building and manipulating domains. These
also update the Nagios config files as necessary. I use a good old text
editor for anything beyond that. If you get the initial set up well
organised it really isn't too difficult to maintain.
