vdsm.log during 'hosted-engine --vm-start'

(I apologize if I categorized this bug horribly.. first bug I've filed on RHEV/oVirt.)

Description of problem:

For a while now, I've been unable to start my hosted engine vm using `hosted-engine --vm-start`

The only indication of a problem occurs in vdsm.log.  See below.

Thread-2143::ERROR::2016-08-03 20:43:42,990::vm::759::virt.vm::(_startUnderlyingVm) vmId=`6406669d-7df3-4719-a3ae-bf82f523ff03`::The vm start process failed

Version-Release number of selected component (if applicable):
vdsm-4.17.33-1.el7ev.noarch
ovirt-hosted-engine-ha-1.3.5.7-1.el7ev.noarch
ovirt-vmconsole-1.0.4-1.el7ev.noarch
ovirt-hosted-engine-setup-1.3.7.2-1.el7ev.noarch

How reproducible:
I haven't been able to locate a bug or error like this anywhere else so probably not very reproducible.

Steps to Reproduce:
1. hosted-engine --vm-start
2. VM Doesn't start

Actual results:
Hosted Engine VM doesn't start

Expected results:
Hosted Engine VM starts

Additional info:
I'm not sure where the relevant parts in vdsm.log start and end so I've included the chunk from the log where the VM attempts to start and fails.  It seems like the remote Hosted Engine VM's metadata is corrupt because I'm able to start the VM if I quickly overwrite /var/run/ovirt-hosted-engine-ha/vm.conf using "cat /etc/ovirt-hosted-engine/vm.conf > /var/run/ovirt-hosted-engine-ha/vm.conf; hosted-engine --vm-start"
