OpenBSD cloud-init network fails with set-name

[ivomarino]

when I try to use the following OpenBSD 7.5 cloud image from https://github.com/hcartiaux/openbsd-cloud-image/releases/download/v7.5_2024-05-13-15-25/openbsd-min.qcow2 with this config:

vm create \
-t openbsd-nvme \
-s 4G \
-c 2 \
-m 512M \
-i openbsd-min.qcow2 \
-C -n "ip=192.168.140.172/24;gateway=192.168.140.1;nameservers=192.168.140.1" \
-k /home/syseng/.ssh/id_rsa.pub \
controller-test-openbsd

cloud-init fails during network setup, this is the error:

Tested both this vm-bhyve versions:

pkg search vm-bhyve
vm-bhyve-1.5.0_1               Management system for bhyve virtual machines
vm-bhyve-devel-1.5.0.26_1      Management system for bhyve virtual machines

any suggestions? Thanks

turns out the problem is hardcoded set-name: eth0 on OpenBSD, see: https://github.com/churchers/vm-bhyve/blob/master/lib/vm-core#L284, if we remove this line, or rename eth0 to vio0 everything works fine

Ivo do you know how to use more of the Cloud init features? Is there a way to pass a yaml file or something?

I see you use -C -n to set the network but I use DHCP so I don't need that.

I pass the key with -k but that's about all I know.

How do we use other features like to set the hostname for example? I don't need that either as the hostname get's set to the VM's name, just trying to figure out how to use cloud init.
