When selinux-virt is emerged, the policy does not create/update virtual_domain_context, virtual_image_context files in /etc/selinux/{strict,targeted}/contexts. libvirt uses these files to tell it what context to switch to for performing virtualization functions. Reproducible: Always Steps to Reproduce: 1.emerge selinux-virt 2.emerge kvm 3.Attempt to do something requiring libvirt (such as run kvm) Actual Results: Observe error "error : SELinuxInitialize:115 : cannot open SELinux virtual domain context file '/etc/selinux/strict/contexts/virtual_comain_context': No such file or directory". Verify that the file does not actually exist. Expected Results: No error, and the files exist in the appropriate location. These files are not created by the SELinux build process, but rather are system dependent. However, it appears that they can be modeled after the ones used by RHEL/Fedora (indeed, testing was performed using files from a Fedora system).
I'm apparently on drugs: there is no selinux-virt ebuild.

I never got libvirt working properly, but at least this will keep me focused that it needs to be fixed ;p
