Manage VMs

We need to be able to deploy new VMs using Puppet, in order to:

• make VM deployment more agile than it currently is, and
• pave the way for automatic environment creation.

Some things to take care of:

• Declaration through Hiera
• Network configuration
• OS installation (via image or automated debootstrap)
• Choose which of the below will be tackled and when.

Not for now:

• Partition/device tuning
• Fail/timeout when virt-install fails/timesout
• Name resolution (eg. using dnsmasq)
• Automatic inclusion in Puppet
• Public IP assignement
• DRBD
• Use huge pages for memory allocation
• Libvirt storage pools

Research

Possibilities:

• Puppet:
  • https://forge.puppet.com/modules/cirrax/libvirt
  • https://forge.puppet.com/modules/openstack/nova
  • https://gitlab.com/shared-puppet-modules-group/puppet-ganeti (doesn't allow provisioning)
• FAI: https://fai-project.org/
• Terraform: https://github.com/dmacvicar/terraform-provider-libvirt
