I create a vm using the ubuntu template and the ubuntu server cloud image. However the started VM doesn't seem to be able to obtain an IP address. For networking, I use the vm-bhyve's guidance of virtual switch and tap devices.

I know my network is working because I have also set up a Ubuntu server using the ISO and went through the installation process. That guest is able to obtain a LAN IP address as I expected.

Below are useful information:

Code:
>>> vm img https://cloud-images.ubuntu.com/bionic/20200407/bionic-server-cloudimg-amd64.img
>>> vm create -t ubuntu_server -i bionic-server-cloudimg-amd64.img -C -k ~/.ssh/id_rsa.pub ub3
>>> cat .templates/ubuntu.conf

memory=512M
network0_type="virtio-net"
network0_switch="public"
disk0_type="virtio-blk"

Im having the same situation here. Did you manage to solve it?
I might have some time this week to dive into this too. If I know anything more, I will post an update here.

UPDATE: Using the latest image from cloud-images.ubuntu.com resolved all of my network connectivity issues...
