In a few cases we might set seclabels on a path outside of namespaces. For instance, when restoring a domain from a file, the file is opened, relabelled and only then the namespace is created and the FD is passed to QEMU (see v6.3.0-rc1~108 for more info). Therefore, when restoring the label on the restore file, we must ignore domain namespaces and restore the label directly in the host. This bug demonstrates itself when restoring a domain from a block device. We don't create the block device inside the domain namespace and thus the following error is reported at the end of (otherwise successful) restore: error : virProcessRunInFork:1236 : internal error: child reported (status=125): unable to stat: /dev/sda: No such file or directory error : virProcessRunInFork:1240 : unable to stat: /dev/sda: No such file or directory Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Erik Skultety <eskultet@redhat.com>

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
