    $ cubic create --help
    Create VM instances
    
    This command only creates the VM instance. Use cubic start <instance> to power
    it on and cubic ssh <instance> to connect to it.
    
    Examples:
    
      Create a VM instance with 8 vCPUs, 10G of RAM, 200G of storage:
      $ cubic create example1 --cpus 8 --memory 10G --disk 200G -i debian:trixie
    
      Create a VM instance and forward the instance's HTTP port to the host port 8000:
      $ cubic create example2 --port 8000:80 -i ubuntu:noble
    
      Create a VM instance and forward the instance's DNS port to the host port 5353:
      $ cubic create example3 --port 5353:53/udp -i ubuntu:noble
    
      Create a VM instance with multiple port forwarding rules:
      $ cubic create example4 -p 8000:80/tcp -p 5353:53/udp -i ubuntu:noble
    
      Create a VM instance and install Vim:
      $ cubic create example5 -e "sudo apt install -y vim" -i ubuntu:noble
    
      Create a VM instance without network access:
      $ cubic create example6 --isolate ubuntu:noble
    
    Usage: cubic create [OPTIONS] --image <IMAGE> <INSTANCE>

      -u, --user <USER>
              Username (default: 'cubic')
    
      -c, --cpus <CPUS>

      -m, --memory <MEMORY>
              Memory amount of the VM instance (default: derived from host resources)
    
      -d, --disk <DISK>
              Disk size of the VM instance
              
              [default: 100G]
    
      -p, --port <PORT>
              Forward ports from guest to host (e.g. -p 8000:80 or -p 9000:90/tcp)

          --isolate
              Isolate the VM instance from network
    
      -v, --verbose
              Increase logging output
    
      -q, --quiet
