If you've ever tried running a huge page backed guest under different user than in qemu.conf, 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.
