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
