Hi all,
I'm experiencing some difficulties using oVirt 3.6 latest snapshot.
I'm trying to trick the self-hosted-engine setup to create a custom engine vm
with 3 nics (with fixed MACs/UUIDs).
The GlusterFS volume (3.7.5 hyperconverged, replica 3, for the engine vm) and
the network bridges (ovirtmgmt and other two bridges, called nfs and lan, for
the engine vm) have been preconfigured on the initial fully-patched CentOS 7.1
host (plus other two identical hosts which are awaiting to be added).
I'm stuck at a point with the engine vm successfully starting but with only one
nic present (connected to the ovirtmgmt bridge).
I'm trying to obtain the modified engine vm by means of a trick which used to
work in a previous (aborted because of lacking GlusterFS-by-libgfapi support)
oVirt 3.5 test setup (about a year ago, maybe more): I'm substituting the
standard /usr/share/ovirt-hosted-engine-setup/templates/vm.conf.in with the
following:

but unfortunately the vm gets created like this (output from "ps"; note that
I'm attaching a CentOS7.1 Netinstall ISO with an embedded kickstart: the
installation should proceed by HTTP on the lan network but obviously fails):

There seem to be no errors in the logs.
I've tried reading some (limited) Python setup code but I've not found any
obvious reason why the trick should not work anymore.
I know that 3.6 has different network configuration/management and this could
be the hot point.
Does anyone have any further suggestion or clue (code/logs to read)?
Many thanks in advance.
Kind regards,
Giuseppe
