I am trying to set up a test kvm virtual machine on a core2 quad system. I have managed to thread my way through bridging eth0 and I have a CentOS-5.4 dvd iso prepared. Using virt-manager, when I try and add a new guest then I get the error reproduced below. Now, I know that I can 'fix' this by building a local mod via audit2allow and installing via semodule. However, I cannot seem to find this particular problem when I Google for it. Therefore, it seems likely that I have done something wrong rather than having encountered a bug. Does anyone have any suggestions as to what step I may have missed in setting up a kvm guest? All I have done so far is: Install qemu. Set libvirtd to start at boot. Bridge eth0 to br0 via customs ifcfg-X scripts in /etc/sysconfig/network-scripts. Run virt-manager. Add a new guest. Summary: SELinux is preventing qemu-system-x86 (qemu_t) "read" to rtc (clock_device_t). Detailed Description: SELinux denied access requested by qemu-system-x86. It is not expected that this access is required by qemu-system-x86 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. Allowing Access: Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for rtc, restorecon -v 'rtc' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
