Description of problem
libvirt doesn't relabel sockets in nbd: backing URLs on rhel8

Version-Release number of selected component (if applicable):
virt-v2v-1.42.0-14.module+el8.5.0+11846+77888a74.x86_64
libguestfs-1.44.0-3.module+el8.5.0+10681+17a9b157.x86_64
libvirt-libs-7.5.0-1.module+el8.5.0+11664+59f87560.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a rhel8.5 instance which has installed virt-v2v on OSP16.2 environment, we called the instance as 'v2v conversion appliance', enable selinux on 'v2v conversion appliance'
# getenforce
Enforcing

2. Convert a guest from vmware to openstack by virt-v2v with vddk

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct

Actual results:
As above description


Expected results:
Not set environment variable "export LIBGUESTFS_BACKEND=direct" during virt-v2v openstack conversion if selinux is enabled
