How to:
Create a new VM
- Have a login to Lamarr via Ansible
- Install virt-manager
- Connect to Lamarr with your login. (Requires your key to be there as ID_RSA) (?need to be root?)
- Create a new VM on Lamarr. Use local to store the virtual drives
- Set suitable resources
- Set network to join bridge br0
- Start and have fun
