Description Sascha Thomas Spreitzer 2009-08-15 04:57:07 EDT
Description of problem:
SELinux is preventing qemu-kvm (svirt_t) "setrlimit" svirt_t. 
SELinux denied access requested by qemu-kvm. It is not expected that this access is required by qemu-kvm and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. 

Version-Release number of selected component (if applicable):
[~]$ rpm -qa|grep -i kvm
qemu-kvm-0.10.5-3.fc11.x86_64
etherboot-zroms-kvm-5.4.4-16.fc11.noarch
[~]$ rpm -qa|grep -i virt

virt-manager-0.7.0-5.fc11.x86_64
virt-top-1.0.3-4.fc11.x86_64
