Hello,
it is not clear to me the exact workflow in case of testing what in object.

For sure first step is to install base node from iso.
NGN has no more read only filesystem.
Does this mean that I have to set up eg multipath for FC LUNs (engine and data domain) before running the engine setup via cockpit?
Or when I specify FC in type of storage domain it would ask and setup automatically multipath for me?

No, it doesn't: HBA and mutipath are supposed to be directly configured before running hosted-engine-setup.
It's exactly the same as for vlan and bonding.

Ah, ok.

So I can also customize my multipath.conf file on oVirt Node as desired, if storage vendor requires it, using

# VDSM REVISION 1.3

# VDSM PRIVATE

as I do in regular CentOS 7, correct?

And if so, what is the mapping of "1.3" in VDSM REVISION line above?

I didn't find reference in oVirt docs and also in RHEV kb I only found this:

https://access.redhat.com/solutions/43458

that doesn't clarify much in my opinion and seems to cover version 4.x in the summary of knowledge base article, but then I don't seem to find its real application...

Thanks,
