Howdy.
What version of OpenBSD are you running? My guess based on the vm.conf
is 6.2, is that correct?
Some comments about networking, independent of version:
* Remove "tap0" from the "test.vm" config section. If you copied that
verbatim to another "vm", only one would be running since you
specified a particular tap interface to use. Instead leave the "tap0"
off to tell vmd to use the next available tap interface.
* If you plan on running more than 4 vms at a time (defined in vm.conf
or via vmctl directly), create more tap interfaces now with MAKEDEV
(example to create two more taps...cd /dev; doas ./MAKEDEV tap4 tap5).
I would recommend running --current as it has all the bug fixes for
vmm/vmd along with cdrom support, if you need it. If you are going to
run --current, you'll need to change your switch definition in vm.conf.
Take a look at https://www.openbsd.org/faq/current.html and look for:
2017/10/29 - vmd(8): switch configuration for more details.
