You cannot ssh into a VM when using "networkType: OVNKubernetes"

always

1. Perform an IPI install on baremetal and set the following in the install-config.yaml
   networking:
   machineNetwork:
   - cidr: 172.22.0.0/16
   networkType: OVNKubernetes
2. Install openshift virtualization
3. Create a VM using the GUI and select the box to enable ssh access to the vm
4. Attach an ssh public key
5. Start the VM
6. Try to ssh into the VM.

get the following message:
ssh: connect to host console-openshift-console.apps.cluster.example.org port 30378: Connection timed out

a successful connection to the VM

Apllying the following command will allow ssh access into the VM.

oc patch network.operator cluster -p '{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"gatewayConfig":"routingViaHost":true}}}}}' --type=merge

It would be useful to have this listed in the documentation on creating a VM.

Table 4.6 in the following documentation mentions this option.
https://access.redhat.com/documentation/en-us/openshift_container_platform/4.10/html-single/networking/index

But without good understanding of OpenShift networking, this may not be enough for someone to understand this needs to be done.
