Description Daniel Berrangé 2007-06-15 17:03:25 UTC 
Description of problem:
Bug 202636  for Xen in RHEL-5.1  adds ability for xenconsoled to persistently
log guest & hypervisor console data to files in /var/log/xen/console. The
current SELinux policy does not allow it to do this, so we need extra rules added.

Version-Release number of selected component (if applicable):
selinux-policy-2.4.6-75.el5

How reproducible:
Always

Steps to Reproduce:
1. Edit /etc/sysconfig/xend and set XENCONSOLED_LOG_GUESTS=yes
2. Reboot
3. Start a new PV guest 'rhel5pv'
  
Actual results:
No log file 
type=AVC msg=audit(1181955852.515:55): avc:  denied  { create } for  pid=3320
comm="xenconsoled" name="guest-rhel5pv.log"
scontext=system_u:system_r:xenconsoled_t:s0
tcontext=system_u:object_r:xend_var_log_t:s0 tclass=file


Expected results:
Log file /var/log/xen/console/guest-rhel5pv.log  created

You can add this rule by executing the following command

# grep xenconsol /var/log/audit/audit.log | audit2allow -M myxen
# ls semodule -i myxen.pp

Fixed in selinux-policy-2.4.6-76
