They are...

Here we are, all credit to Valery Ushakov. There are quite a bit of
mail exchanges on port-amd64 regarding these, but the gist is as
follows.

1. Install devel/kbuild and devel/yasm. Earlier versions of kbuild
were unusable and there was a package in wip, now the version present
in pkgsrc works just fine.

2. make sure /usr/src and /usr/xsrc are populated with the sources for
the exact version you are running; I have them nfs-mounted from my
build host. As the build process requires the exact system sources, it
would be perhaps difficult or impossible to have this in pkgsrc;
adding the necessary bits to the NetBSD source tree on the other hand
would be a lot of work for not that big return.

3. Download the sources from Oracle VirtualBox, at the moment
https://download.virtualbox.org/virtualbox/6.1.4/VirtualBox-6.1.4.tar.bz2
.

4. Extract the sources somewhere, cd to VirtualBox-6.1.4.

5. Create LocalConfig.kmk with the following contents:

VBOX_WITHOUT_HARDENING := 1
VBOX_ONLY_ADDITIONS := 1
VBOX_WITH_ADDITION_DRIVERS := 1
VBOX_WITH_X11_ADDITIONS := 1
VBOX_ONLY_ADDITIONS_WITHOUT_RTISOMAKER := 1

ifeq ($(KBUILD_TARGET), netbsd)
TEMPLATE_VBOXGUESTR3EXE_LIBS     = $(TEMPLATE_VBOXR3EXE_LIBS) crypt
endif

6. Apply the following small patch (perhaps an oversight by whoever
has commited the corresponding file at VirtualBox, it works for me):

# cat sleepqueue-r0drv-netbsd.patch

         sleepq_unsleep,
         sleepq_changepri,
         sleepq_lendpri,

(The error message in the build process suggests it).

7. Go ahead with the build process:

kmk KBUILD_VERBOSE=2 BUILD_TYPE=release

The above should finish without an error and leave you with

8. Now I usually place all these files in /usr/local/bin/additions
directory, to keep them away from the system and allow me to easlily
replace them.

9. Create the directory for the kernel module:

# mkdir /stand/amd64/9.99.54/modules/vboxguest ###(obviously adjust to
your NetBSD version)
# cp /usr/local/bin/additions/vboxguest.kmod
/stand/amd64/9.99.54/modules/vboxguest

10. I modify my /etc/rc.local, adding

....
if [ -x /stand/amd64/`uname -r`/modules/vboxguest/vboxguest.kmod ]; then
        /sbin/modload vboxguest
fi

if [ -x /usr/local/bin/additions/VBoxService ]; then
        /usr/local/bin/additions/VBoxService --pidfile /var/run/VBoxService.pid
fi
.....

On first execution of '/sbin/modload vboxguest' you will get

# ls -l /dev/vboxguest
crw-rw-rw- 1 root wheel 357, 0 Nov  8 00:07 /dev/vboxguest

So, no need to create it.

11. Now try

. /etc/rc.local

You shoould get:

 . /etc/rc.local

and in the log file

12. Make sure you get

/usr/local/bin/additions/VBoxClient --display
/usr/local/bin/additions/VBoxClient --clipboard

executed whenever you start X (in your .xinitrc, .xsession or the
environment you are using).

As I mentioned before, dynamic resizing now works, but not seamless.
You also can't mount a shared folder (that's never been an issue for
me).

13. Make sure "ws" driver is used for the mouse.
