If built without attr support removing any image will trigger
qemuBlockRemoveImageMetadata (the one that emits the warning)
-> qemuSecurityMoveImageMetadata
-> virSecurityManagerMoveImageMetadata
-> virSecurityDACMoveImageMetadata
-> virSecurityDACMoveImageMetadataHelper
-> virProcessRunInFork (spawns subprocess)
-> virSecurityMoveRememberedLabel
In there due to !HAVE_LIBATTR virFileGetXAttrQuiet will return
ENOSYS and from there the chain will error out.
That is wrong and looks like:
libvirtd[6320]: internal error: child reported (status=125):
libvirtd[6320]: Unable to remove disk metadata on vm testguest from
/var/lib/uvtool/libvirt/images/testguest.qcow (disk target vda)
This change makes virSecurityDACMoveImageMetadataHelper and
virSecuritySELinuxMoveImageMetadataHelper accept that
error code gracefully and in that sense it is an extension of:
5214b2f1a3f "security: Don't skip label restore on file systems lacking XATTRs"
which does the same for other call chains into the virFile*XAttr functions.

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.
