Hi Jonas,
Can you please share the full log file located in
/var/log/ovirt-hosted-engine-setup ?
My guess you hit [1], this is the fix for that [2] (not merged yet).
You can install the rpm with the fix from Jenkins CI [3] and then run the
following command:
hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true
Regarding the "disk-memory-leak", can you please open a bug for that?
Regards,
Asaf

Hi!
A short addendum:
I have now also tried to perform the installation using the oVirt Node
distribution as a basis, but that also ended with the same problem. So
it does not seam to be an issue with the underlying CentOS installation,
but rather with my general setup or parameters.
Regards
Jonas
