nova-hyperv: Import-Module : nova-hyperv - 'CharmHelpers' was not loaded because no module was found in any module directory

This is with v1 of the charm and the Juju version 1.22. The charm never goes to error state but deployer shows installing. Looking at the all machine log, the only error that's shown is failure to load CharmHelpers.

Not sure if this can be recreated with V2. I will update this bug if it's recreated.

I have attached the all machines debug log
