This charm is intended as a subordinate charm to the nova-compute charm and its purpose is to set/override libvirt specific parameters such as IOPS per second.
To achieve this goal, the charm relies on libvirt specific commands such as
virsh blkdeviotune
Example usage:
juju deploy libvirt-companion
juju config libvirt-companion read-iops-sec=200 write-iops-sec=100
juju config libvirt-companion excluded-instances "ae52af9a-5799-24fe-0501-f6ec802ee889 bcb8f4ec-6337-4b69-a408-2498578e78bf"
juju add-relation libvirt-companion nova-compute
To remove it:
juju config libvirt-companion read-iops-sec=0 write-iops-sec=0
juju remove-application libvirt-companion
