I'm investigating the issue on master.
In my case I choose to configure the engine VM with a static IP address and
engine-setup failed on the engine VM since it wasn't able to check
available OVN related packages.

So we have two distinct issues here:
1. we are executing engine-setup with --offline cli option but the OVN
plugins are ignoring it.

2. the engine VM has no connectivity.
I dig it a bit and I found that the default gateway wasn't configured on
the engine VM although it's correctly set in cloud-init meta-data file.
So it seams that on 7.4 cloud-init is failing to set the default gateway:

[root at enginevm ~]# nmcli con show "System eth0" | grep -i GATEWAY
connection.gateway-ping-timeout:        0
ipv4.gateway:                           --
ipv6.gateway:                           --
IP4.GATEWAY:                            --
IP6.GATEWAY:                            fe80::c4ee:3eff:fed5:fad9
[root at enginevm ~]# nmcli con modify "System eth0" ipv4.gateway
Error: value for 'ipv4.gateway' is missing.
