Description of problem:

I have deployed a regular ovs-dpdk + sriov deployment using ifcfg and once the deployment is up, I executed the following command to migrate to nmstate:

os-net-config -p nmstate --purge-provider ifcfg --detailed-exit-codes --debug –
verbose

Migration fails, i see the following errors in os-net-config log:

Version-Release number of selected component (if applicable):
I deployed current available puddle (RHOS-17.1-RHEL-9-20240909.n.1) and update os-net-config in overcloud image manually before overcloud deployment. I used
git switch -c stable/wallaby origin/stable/wallaby

How reproducible:
Deploy ovs-dpdk sriov deployment using ifcfg
Migrate once the deployment is done
os-net-config -p nmstate --purge-provider ifcfg --detailed-exit-codes --debug –
verbose

Actual results:
Migration does not happen as some errors are reported

Expected results:
Migration to nmstate should happen
