[Caleb-Ellis]

Done

QA

MAAS deployment

To run this branch you will need access to one of the following MAAS deployments:

• Karura
• Bolla
• A development MAAS
• A local snap MAAS (this will not usually have machines)

Running the branch

You can run this branch by:

• Serving with dotrun
• Building in a development MAAS

QA steps

• Open the network tab in the browser console check that the websocket connection can be found
• Open the Deploy form for a machine and submit the form without checking the "Deploy KVM" checkbox
• Check that the websocket request does not include either install_kvm or register_vmhost
• Cancel deploying and open again, this time checking the "Deploy KVM" checkbox and the "LXD" radio button before submitting
• Check that the websocket request includes register_vmhost but not install_kvm
• Cancel deploying and open again, this time checking "libvirt" before submitting
• Check that the websocket request includes install_kvm but not register_vmhost
