shortdesc: STONITH for libvirt (kvm / Xen)
longdesc: >
Uses libvirt as a STONITH device to fence a guest node.
Create a separate resource for each guest node in the cluster.
Note that the recommended fencing mechanism is SBD whenever
a shared storage device (like a SAN) is available.

- name: id
shortdesc: Resource ID (Name)
example: stonith-libvirt
required: true
type: resource
- name: target

required: true
- name: hostlist
shortdesc: "List of controlled hosts: hostname[:domain_id].."
longdesc: >
The optional domain_id defaults to the hostname.
type: string
required: true
- name: hypervisor_uri
longdesc: >
URI for connection to the hypervisor.
driver[+transport]://[username@][hostlist][:port]/[path][?extraparameters]
e.g.
qemu+ssh://my_kvm_server.mydomain.my/system (uses ssh for root)
xen://my_kvm_server.mydomain.my/ (uses TLS for client)

example: power_cycle
type: string
shortdesc: Guest Reset Method
