Description Sebastian Trebitz 2013-03-05 14:19:03 UTC
Description of problem:
SELinux is preventing /usr/bin/qemu-kvm from using the 'setrlimit' accesses on a process.

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

If you believe that qemu-kvm should be allowed setrlimit access on processes labeled svirt_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 qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
