Flying Circus QEMU virtual machine management

This package provides a utility to manage virtual machines and their life cycle in the Flying Circus. We try to keep specifics of our environment out of there, but we make a few assumptions:

• VM disks (root, swap, tmp) are stored in Ceph
• There is a script create-vm that will prepare a fresh root disk image.

The utility allows you to

• start, stop and migrate VMs between hosts
• run a daemon that enforces the policy about running VMs given by a set of config files
• resize disks.

Config format

Generic template

The Qemu config file will be generated from a template. If no template is found in /etc/qemu/qemu.vm.cfg.in, a built-in default template will be used. Refer to qemu.vm.cfg.in in the source distribution.

Per-VM configuration

Expects a config file for each VM in /etc/qemu/vm/*.cfg.

The config file format is YAML.

Format:
