[DRAFT] add hosted-engine support
This adds a plugin subpackage for the hosted engine and dependencies
there are still some setup issues to debug within the persisted node
environment that will continue to be picked up in F20 to finish
Documenting a few things for later reference:
- bridge setup intermittent failures in ovirt-hosted-engine-setup
second attempt passes
- after install the node gets rebooted, possibly fenced?
- network / libvirt / vdsm configs need to be persisted
- on reboot, the storage domain need to be manually setup
After the reboot here are steps to get vm back running
- vdsm-tool configure --force (persisted files should fix this)
- hosted-engine --connect-storage
- hosted-engine --start-pool
- hosted-engine --vm-start
- vdsClient -s localhost list
Once done the vm should launch however it's not able to communicate
with the bridge or external network
