This machine runs 4 more VM and this one (huge) should be 5th.

Try this:

# cd /dev && sh MAKEDEV tap4

By default I believe on amd64 we create tap[0-3]. You might need to
define additional special files to represent 4+ taps.

I really think that this should be documented at 
https://www.openbsd.org/faq/faq16.html 
<https://www.openbsd.org/faq/faq16.html>

It's in man vm.conf, to an extend:

CAVEATS
     Each guest requires one tap(4) device per assigned interface and 
one
     pty(4) device.  Administrators may need to create additional 
devices
     using MAKEDEV(8).

Anyway, right now it fails as:

vmctl: start vm command failed: Invalid argument

and if I revert may changes (to 10G for example) at cat 
/etc/login.conf.d/vmd from:
vmd:\
        :datasize=100G:\
        :tc=daemon:


it's failed as (which is expected):
vmctl: start vm command failed: Cannot allocate memory
