Ganeti is a cluster management software using virtualization technologies such as Xen or KVM and other open source software. Currently LXC(Linux Containers) is a one of hypervisor supported by Ganeti, but it is still experimental feature. While managing limited hardware resources as a server cluster environment, using LXC as a hypervisor can be a great choice. This project aims to improve LXC support on Ganeti to make it practical feature in production.
