That was it. Thanks!
I've set a fixed IP address to bg0 in the host:
# ifconfig bge0 192.168.0.9 255.255.255.0
Now the guest can DHCP:
# vmctl start vm.test -c
Connected to /dev/ttyp1 (speed 9600)

Welcome to the OpenBSD/amd64 6.1 installation program.
(I)nstall, (U)pgrade, (A)utoinstall or (S)hell? I
At any prompt except password prompts you can escape to a shell by
typing '!'. Default answers are shown in []'s and are selected by
pressing RETURN. You can exit this program at any time by pressing
Control-C, but this can leave your system in an inconsistent state.
Terminal type? [vt220]
System hostname? (short form, e.g. 'foo') vmtest
Available network interfaces are: vio0 vlan0.
Which network interface do you wish to configure? (or 'done') [vio0]
IPv4 address for vio0? (or 'dhcp' or 'none') [dhcp]
DHCPDISCOVER on vio0 - interval 1
DHCPOFFER from 192.168.0.1 (6c:b0:ce:3f:2e:b7)
DHCPREQUEST on vio0 to 255.255.255.255
DHCPACK from 192.168.0.1 (6c:b0:ce:3f:2e:b7)
bound to 192.168.0.13 -- renewal in 1800 seconds.
IPv6 address for vio0? (or 'autoconf' or 'none') [none]
Do you have any idea how to avoid this issue?
