cloud-init-start

Quickly bring up Ubuntu or FC20 Cloud instances in local KVM with virsh using cloud-config.

Requirements:

• Make
• wget
• cloud-utils (cloud-localds)
• qemu/kvm
• libvirt (virsh)
• virtinst (virt-install)

Usage:

# Define cloud-config data
$ editor myhost01.user-data

The cloud-config user data looks something like this:

#cloud-config
hostname: example
manage_etc_hosts: True

ssh_pwauth: False

ssh_authorized_keys:
 - ssh-rsa AAAAB.....

package_upgrade: true

You can find more examples of what you can do with cloud-config from the cloud-init documentation.

If you saved the cloud-config to file myhost01.example, you can now launch a virtual machine.

# Ubuntu 14.04 Trusty
$ make ubuntu-myhost01

  OR

# Fedora Core 20
$ make fc20-myhost01

The Makefile:

1. downloads the base cloud image (reused for new VMs),
2. creates a root disk image for it, packages the user-data to an ISO 9660 file, and
3. defines the machine with virt-install so it can be started.

You can now start the VM with:

$ virsh start myhost01

What you do with your VM after this is up to you.
