Virsh power type (UI)

Consider a machine backed by VM. Below, a ‘Power type’ of Virsh has been selected, and the ‘Power address’ of qemu+ssh://ubuntu@192.168.1.2/system has been entered (replace values as appropriate). The value of ‘Power ID’ is the VM domain (guest) name, here node2.

Pro tip: The machine’s hostname – according to MAAS – is a randomly chosen string (here dear.ant). You should change this hostname to something descriptive, that helps you remember why this machine is in your MAAS network.

Webhook

It’s important to understand that the Webhook power driver is more generic than other drivers, so it has some flexibility that the underlying power driver may not support. For example, Webhook doesn’t require a username or password for the power driver, because not all power drivers work that way. Nevertheless, the power driver you’re connecting to Webhook may actually require a username and/or password. Understanding and implementing these fields correctly for the chosen back-end power driver is the user’s responsibility.

To that end, the “Required” column for this driver refers only to whether Webhook requires a value in each field. Just because a field is optional for Webhook itself does not mean that the underlying power driver will ultimately allow that field to be unspecified.

Form field	Description	Required (by Webhook)
Power type	Webhook (from drop-down list)	Required
URI to power on the node	URI to access power driver’s API for power on	Required
URI to power off the node	URI to access power driver’s API for power off	Required

Regex to confirm the node is off	Regex expression that will return a string if the power is off, and no string if the power is on	Required, defaults supplied
Power user	Username to log into the power driver	Optional
Power password	Password to access unit	Optional
Power token	Power driver API token (used instead of user and password, if set)	Optional
Verify SSL connections…	Boolean, whether or not to verify SSL connections with the system’s root CA certificate	Required
