Yes, it's the hosted-engine HA agent which keeps VDSM up so host-deploy fails on that.
The capability to re-deploy an hosted-engine host from the Web UI is not available on oVirt 3.5, it will included in 3.6; please help us testing it on the first beta in  a few weeks.

By the way, why are you trying to re-deploy an host-deploy host from the web UI?
