Bug 910806

+++ This bug was initially created as a clone of Bug #896013 +++

Derek found that there are several new / different AVCs; the primary difference between his installation and where I performed testing is that his occur on x86 VMs

x86 failures

audit2allow spat out the following, given the above:

#============= svirt_t ==============
allow svirt_t nova_var_lib_t:file { read ioctl open getattr };

This is using qemu-system-x86_64, as it is launched within a VM:

My bare-metal openstack deployment does not exhibit this behavior:

Could this be the problem?

[root@ps2 ~(keystone_admin)]$ ls -lZ /usr/libexec/qemu-kvm
-rwxr-xr-x. root root system_u:object_r:qemu_exec_t:s0 /usr/libexec/qemu-kvm
[root@ps2 ~(keystone_admin)]$ ls -lZ /usr/bin/qemu-system-x86_64 
lrwxrwxrwx. root root system_u:object_r:bin_t:s0       /usr/bin/qemu-system-x86_64 -> /usr/libexec/qemu-kvm

No

SELinux is still transitioning properly.  The problem is the target is either mislabeled, IE libvirt did not relabal content in /var/lib/nova/instances

Or all virt machines need to be able to read content in /var/lib/nova/instances
