Description of problem:
when I have a box with two VFs switched to vfio-pci driver I cannot restart openvswitch service with default permissions in /etc/sysconfig/openvswitch (openvswitch:hugetlbfs)
but I can after changing those to root:root

The system is booted with biosdevname=1 default_hugepagesz=1G hugepagesz=1G hugepages=32 iommu=on intel_iommu=pt kernel options

Version-Release number of selected component (if applicable):
dpdk-22.11-4.el9.x86_64
openvswitch2.17-2.17.0-98.el9fdp.x86_64
kernel-5.14.0-350.el9.x86_64

How reproducible:
always

Steps to Reproduce:
[root@dell-per720-03 ~]# echo 2 > /sys/class/net/p4p1/device/sriov_numvfs
[root@dell-per720-03 ~]# dpdk-devbind.py -b vfio-pci 0000:42:10.2
[root@dell-per720-03 ~]# dpdk-devbind.py -b vfio-pci 0000:42:10.0
[root@dell-per720-03 ~]# systemctl restart openvswitch
[root@dell-per720-03 ~]# vi /etc/sysconfig/openvswitch (I've changed the permissions back to openvswitch:hugetlbfs)
[root@dell-per720-03 ~]# systemctl restart openvswitch

Actual results:
A dependency job for openvswitch.service failed. See 'journalctl -xe' for details.

Expected results:
correct openvswitch service restart
