Hi everyone! I'm new to Kubernetes and KubeVirt, and I'm trying to figure out how I can SSH into a virtual machine (VM) that I've deployed using KubeVirt. I've set up a Kubernetes cluster on AWS with an EC2 instance acting as my Ansible controller. This controller needs to access the VM for configuration via Ansible playbooks. Is it possible to SSH from the Ansible controller into a VM that's running inside a pod? If so, what are the best practices or steps to do this? I really appreciate any guidance you can provide!

You might also want to check if there are any firewall rules on your node that could be blocking port 22. And don't forget to make sure SELinux is disabled, as it can prevent SSH access.
Make sure you have the virtctl tool installed, as it makes SSH access easier. If the SSH public key from your Ansible controller is already added to the VM, you can simply run `virtctl ssh ` to connect. The KubeVirt docs have a section on SSH access that might be useful too!
Yes, it’s definitely possible to SSH into a KubeVirt VM! You can either assign it a static IP, use NodePort with a KubeVirt Service, or even utilize the virtctl tool as an SSH proxy. Exposing port 22 is key, and ensure that your VM's SSH server is correctly set up so that it’s reachable.
To SSH into your KubeVirt VM, you'll need to set up proper networking for your pod. Check the KubeVirt documentation on configuring interfaces and networks for more details. This will help your VM communicate with the outside world using Kubernetes network interfaces.
Also, consider using the kubevirt.core Ansible collection; it can help dynamically discover VMs and simplify your management tasks.
