My last try was, during Packer build, to append "add_drivers+="

I can still boot using Rescue mode on VMWare, then, I can see that
sd_mod is inside of initramfs as expected (lsinitrd FTW) but, dracut
does not load it! I tried "force_drivers+=" sd_mod", doesn't work
too...

Weird is that, while during Rescue, if I run "dracut -f" again, then,
it works! Normal boot proceeds... But this is unacceptable, because I
can not ship a half-broken VMDK and tell customers to first boot on
Rescue, run "dracut -f" and then, use the system.

So, why the heck the "dracut -f" executed when as a KVM guest have no
effect for later ESXi usage?

What am I missing?

I really appreciate any help!

Is this possible the hostonly option in dracut causing fun?

"On RHEL-7 the hostonly mode is the default mode. Generic "non-hostonly"
 images are created, if the dracut-config-generic rpm is installed.  The
 rescue kernel entry in the bootloader menu is also a generic image."
