Description Giovanni Campagna 2011-07-13 16:33:57 UTC
SELinux is preventing /usr/bin/virsh from using the 'setsched' accesses on a process.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that virsh should be allowed setsched access on processes labeled virsh_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep virsh /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
