Once the engine correctly imported the hosted-engine storage domain, a
couple of OVF_STORE volumes will appear there.
Every modification to the engine VM configuration will be written by the
engine into that OVF_STORE, so all the ovirt-ha-agent running on the
hosted-engine hosts will be able to re-start the engine VM with a coherent
configuration.

Till the engine imports the hosted-engine storage domain, ovirt-ha-agent
will fall back to the initial vm.conf.

In you case the OVF_STORE volume is there,
but the agent fails extracting the engine VM configuration:
MainThread::INFO::2016-11-24
17:55:04,914::ovf_store::112::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(getEngineVMOVF)
Extracting Engine VM OVF from the OVF_STORE
MainThread::INFO::2016-11-24
17:55:04,919::ovf_store::119::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(getEngineVMOVF)
OVF_STORE volume path: /rhev/data-center/mnt/glusterSD/10.70.36.79:
_engine/27f054c3-c245-4039-b42a-c28b37043016/images/fdf49778-9a06-49c6-bf7a-a0f12425911c/8c954add-6bcf-47f8-ac2e-4c85fc3f8699
MainThread::ERROR::2016-11-24
17:55:04,928::ovf_store::124::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(getEngineVMOVF)
Unable to extract HEVM OVF

So it tries to rollback to the initial vm.conf, but also that one seams to
miss some values and so the agent is failing:
MainThread::ERROR::2016-11-24
17:55:04,974::agent::205::ovirt_hosted_engine_ha.agent.agent.Agent::(_run_agent)
Error: ''Configuration value not found:
file=/var/run/ovirt-hosted-engine-ha/vm.conf, key=memSize'' - trying to
restart agent

Both of the issue seams storage related, could yuo please share your
gluster logs?
