I believe at least on some distros /var/run should be soft-linked to
/run, otherwise whoever cleans up those directories (the command name
escapes me right now) will only remove files from /run and leave
/var/run (and therefore /var/run/xen/xenstored.pid) untouched.

And because xencommons checks for existence of this this file before
starting xenstored the latter never starts.
