It's cumbersome to setup per guest facility for syslog. We don't want
console log from different guests mix together in one file.

Logrorate runs periodically. It doesn't actively limit the disk space
consumed.

The combination of syslog and logrotate can't prevent a guest from
filling up Dom0 disk as far as I can tell. I'm happy to know if there is
some sort of simple configuration we can ship with open source Xen.
