The policy has to be dynamic - customized before launching qemu, and able to change during process life-cycle for events like hot-plug and migration. I don't see the need for the qemu process to change its permissions, since the managing libvirt can change the policy during process life (I assume selinux policy can change while a process is already running). The reason the policy has to be created just before process launch is that the VM can be run on different hosts, and I don't think it makes sense to synchronize the policy of all possible guests on all hosts all the time (and the policy is enforced at host level, not storage level for example). Also, we need to cover the SAN use case, where each image is probably an LV in LVM. -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
