If you've ever tried running a huge page backed guest under different user than root, you probably failed. Problem is even though we have corresponding APIs in the security drivers, there's no implementation and thus we don't relabel the huge page path. But even if we did, so far all of the domains share the same path: /hugepageMount/libvirt/qemu Our only option there would be to set 0777 mode on the qemu dir which is totally unsafe. Therefore, we can create dir on per-domain basis, i.e.: /hugepageMount/libvirt/qemu/domainName and chown domainName dir to the user that domain is configured to run under.

I jut hope that by the time the command line is built domain already has id allocated. Not really. We don't expose the path anywhere, and whenever it is needed we construct it. I've tested this and basically the only problem I ran into was that we don't build the path on domain hotplug (rather than on domain startup), but it is trivial to fix. Michal

Since its introduction in 2012 this internal API did nothing. Now it's finally the right time to put it into a good use. It's implementation is fairly simple and exactly the same as virSecurityDomainSetPathLabel.
