I’m assuming that you’ve already gone through the process of getting KVM installed on your Linux host; if you need help with that, a quick Google search should turn up plenty of “how to” articles (it’s basically a sudo apt-get install kvm operation). Next, you need to authenticate the hypervisor to NVP.

The fleetctl doesn’t expose any options to configure the SSH connection, and it assumes you’ll be using public key authentication. OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem.
