Ask HN: Cloud-Localds Alternative for macOS?

I'm using qemu to build Ubuntu server VMs on my mac, and I want to use cloud-init to configure the VM. Everything works fine but there is one command I cannot run on my mac:

    cloud-localds -v --network-config=network.cfg ubuntu.img cloud_init.cfg

I haven't found anything similar to cloud-localds available on Mac. So, it seems that in order to boot my Ubuntu VM I first need to boot another VM to run cloud-localds... a bit frustrating. Do you know how can I achieve the same as the command line above but in MacOS?
