Hi,
it's a kind of race condition consuming the output of hosted-engine
--vm-status --json that, during service startup time, could appear not
complete.
We tracked it here:
https://bugzilla.redhat.com/1540926

oVirt 4.2.2 rc3 will contain a fix for that.

It failed really late so at the end your env should be already OK, maybe
you can just have the bootstrap local VM as a leftover external VM in the
engine but you could simply manually delete it.
I don't see other drawbacks.
