A thing I just tried: if I run "setfiles -n" it gives me the wrong
labels for the files:
setfiles -nd /etc/selinux/targeted/contexts/files/file_contexts
'/var/lib/xenstored'
setfiles: /var/lib/xenstored matched by
unconfined_u:object_r:unconfined_home_dir_t:s0
setfiles: /var/lib/xenstored/tdb matched by
unconfined_u:object_r:unconfined_home_t:s0
filespec_eval: hash table stats: 2 elements, 2/65536 buckets used,
longest chain length 1
In /etc/selinux/targeted/contexts/files/file_contexts I have the
following two entries for that directory:
/var/lib/xenstored(/.*)? system_u:object_r:xenstored_var_lib_t:s0
/var/run/xenstored(/.*)? system_u:object_r:xenstored_var_run_t:s0
It sounds like it's not matching the entries in the file...
Here is the AVC message related to xenstored, but I have many others!
type=AVC msg=audit(1204647044.542:940): avc: denied { unlink } for

Thanks for your help.
