OCNE OLVM Provider: /opt/cni/bin Mounted as Read-Only

[sgurijal]

Summary
/opt/cni/bin is mounted as read-only on workload cluster nodes deployed via the OLVM Provider.

Steps to Reproduce

1. 1.Install OCNE 2.0 CLI
2. 2.Install Libvirt
4. Set OLVM environment variables
5. Run:

ocne image create --type olvm --arch amd64 -l debug
ocne image upload --type olvm --file $HOME/.ocne/images/boot.qcow2-1.32-amd64.olvm --arch amd64 --config demo.yaml

6. Create an OLVM Template

7. Start the cluster:

ocne cluster start --config demo1.yaml
export KUBECONFIG=$(ocne cluster show --cluster-name demo1)

Expected Result:

/opt/cni/bin should be mounted as read-write.

Actual Result:

On connecting to workload cluster nodes in OLVM :

ocne cluster console --node demo1-control-plane-7pk7j --direct
sh-4.4# cd /opt/cni/bin
sh-4.4# touch test
touch: cannot touch 'test': Read-only file system

It seems like usr-lib-opt-cni-bin.mount didn't get started when the vm is up. To workaround this is to manually execute systemctl start usr-lib-opt-cni-bin.mount inside the vm.
