Always remember the KISS principle.

Don't.

This is unnecessary complexity. That is bad.

If the host hardware is outside your network thern youy need a
firewall to protect the host for your firewall. That is crazy. Don't.

Run a firewall distro directly on the bare metal of your firewall appliance.

Extra bad plan. Don't.

That is a good thing. But you still don't need it.

Irrelevant, as far as I can tell.

Do not run your firewall in a VM.

So run a firewall distro on it.

> With the "new" hardware that I have purchased, Palo Alto VM-Series Software Firewall no longer keeps shutting down and no longer keeps rebooting (no more critical errors).

Still a bad plan.

KEEP IT SIMPLE.
