A vague description of what does _not_ happen is less useful than a
clear description of what _does_ happen.

The non-psychics in your audience might know very little about the
network configuration of these virtual machines. If a broadcast DHCP
request does not propagate from a VM to the CAX80 (with its DHCP
server), then I wouldn't expect it to respond.

"check it"? "check" _what_? "check it" _how_?

None of that is a useful problem description. It does not say what
you did. It does not say what happened when you did it. As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

Huh? "not static"? I don't know what that means.

Terminology: A "static" address is configured on the device itself.
What you configure on a (DHCP server on a) router is a reserved dynamic
address, not a static address. Either one should fix the address of a
device, but some implications are different.

_That_ would be a useful test of the CAX80 DHCP server.
