Hey everyone, I've been testing out oVirt 3.4 w/ hosted engine, and while I've managed to bring the engine up, I've only been able to do it manually, using "hosted-engine --vm-start".
The ovirt-ha-agent service fails reliably for me, erroring out with "RequestError: Request failed: success."
I've pasted error passages from the ha agent and vdsm logs below.
Any pointers?
Regards, Jason

Greg, Martin, "Request failed: success" ?
Hi Jason,
I talked to Martin about this and opened a bug [1]/submitted a patch [2]. Based on your mail, I'm not sure if you experienced a race condition or some other issue. This patch should help the former case, but if you're still experiencing problems then we would need to investigate further.
I made these changes to my install and now I get a different error:

I'm attaching my vdsm.log, agent.log and broker.log.

Hi Jason, this bug is already fixed in the latest builds.
I was able to successfully install the hosted engine with the following rpms installed.
1. Install and enable the preview repo as described here: http://www.ovirt.org/OVirt_3.4_Test_Day
and then install the following packages:
http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-ha_create_rp...
http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-setup_create...
--Jirka
I forgot to mention that I've not succeeded on F19 completely. One more problem you might run into is [1]. AFAIK it doesn't have a fix yet, so the installation will be interrupted. But after the host reboots you might try running this: hosted-engine --connect-storage hosted-engine --start-pool hosted-engine --vm-start [1] https://bugzilla.redhat.com/show_bug.cgi?id=1064991 which
Thanks, Greg
