DEMO Caveats

● DEMO 1○ In the playbook, rename demoX to demoY before running the playbook

○ In the RHV UI, remove all references to demoX before creating a new demoY

○ In the RHV UI, remove all user references to demoX before proceeding

● DEMO 2○ Make sure the oVirt guest agent is installed on the template, the playbook may error out on “Wait for

VMs IP”

○ When sealing your VM, do not “rm -rf /var/log/*” since the ovirt-guest-agent directory is needed to start the Guest agent

○ ovirt-vm-infra role requires python-jmespath to be installed on the ansible management node
