Okay, so I found the source of this error. In /usr/local/etc/rc.d/vboxnet
(I have vboxnet_enable in /etc/rc.conf) it attempts to execute the
following command for vboxnet_start:
# initialize configured host-only interfaces
/usr/local/bin/VBoxManage list hostonlyifs >/dev/null
I can run VBoxManage as a normal user without any problems, but when I run
VBoxManage as root it results in the same three errors from my original
post. That is why it errors out during the boot process. I don't know if
that behavior is normal or not.
In any event, don't understand the purpose of the VBoxManage command in
/usr/local/etc/rc.d/vboxnet since, contrary to the immediately preceding
comment, it is only listing (not initializing) hostonly interfaces and
sending the output to dev/null. It seems pointless.
Anyway my conclusion is that the boot time error messages while annoying,
are harmless. I'm still not certain why the error messages just started
showing up in the console log on 3/11.
