    qemu: Create hugepage path on per domain basis · f55afd83
    Michal Privoznik 提交于
    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.
