This is how it should behave normally, it does not kill the VM.
Perhaps check logs, try to find who/what killed it.
Anyway: Earlier today I pushed this patch:
https://gerrit.ovirt.org/109730
Didn't yet get to try verifying it. Would you like to try? You can get
an RPM from the CI build linked there, or download the patch and apply
it manually (in the "gitweb" link [1]).
Then, you can do:
hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true
If you try this, please share the results. Thanks!

Good news. I managed to connect to the VM and solve the problem.
For some odd reason our primary DNS server had upstream connection
issues and all the requests were silently handled by our secondary DNS
server.
Not sure I understand why, but while the ovirt host did manage to
silently spill over to the secondary DNS, the hosted engine, at least
during the initial deployment phase (when it still uses the host's
dnsmasq), failed to spill over to the secondary DNS server and the
deployment failed.
Once I fixed our primary DNS upstream connection issues, the installer
managed to download packages successfully (but failed once I
provisioned the storage, more on that in a different mail).
Many thanks, again, for taking the time to assist me!
(And hope it helps anyone facing the same issue in the future)
