[libvirt] [PATCH 0/5] security: Deal with stale XATTRs

There are some ways users can end up in stale XATTRs. One is sudden power loss, the other is stopping libvirt whilst some domains are running and then rebooting the host. And I believe users will find other creative ways to shut down domains without qemuProcessStop() being called. When that happens our XATTRs will be left behind and not reflect the real state of things (e.g. refcounter). To resolve this, record a timestamp within XATTRs too so that host reboots can be detected.
