[libvirt] [jenkins-ci PATCH v2] lcitool: check for virt-install / ansible-playbook in $PATH

Posted by Daniel P. Berrangé 11 weeks ago
This improves error reporting:

  $ ./lcitool install libvirt-fedora-29
  ./lcitool: Failed to install 'libvirt-fedora-29': [Errno 2] No such file or directory

To

  $ ./lcitool install libvirt-fedora-29
  ./lcitool: Cannot find virt-install in $PATH

Please call this 'ansible_playbook' instead of 'ap_path'...

... and same here.

Other than that, this works and AFAICT addresses all issues Pino
raised for v1, so
