WIth what has static IPs already been tested?

I wantesd to try using this with my RHEV cluster.

I tested first on a rhel7 machine. There I got stuck when my machines wouldn't boot. They just displayed a grub prompt. On closer look it was because the blscfg command is not found.

I suspect this is because the core.img installed in the boot iso is too outdated when done via a rhel7 machine.

I then wanted to try doing it from a rhel8 machine, but there I could not find a way to install python-ovirt-engine-sdk4...

@kristvanbesien Thanks for sharing your experience! I tested the static IPs using a helper node running Fedora 31 and also RHEL 8.1. Don't remember testing with RHEL 7 but I would hope that it would work on RHEL 7.8.

Regarding the python-ovirt-engine-sdk4 rpms not available for RHEL 8, I described a workaround here: https://github.com/noseka1/openshift-auto-upi/blob/master/docs/os_specific_config.md#helper-host-os-specific-configuration You can install the ovirt-engine-sdk4 uisng pip:

$ pip install ovirt-engine-sdk-python

@kristvanbesien You were right. The openshift hosts would not boot when using RHEL7. It is fixed now: https://github.com/noseka1/openshift-auto-upi/issues/5

Static IPs were merge into master and included in the 1.5 release of openshift-auto-upi.
