WebVirtMgr with LXC support

This is the connections page backported from WebVirtMgr 4.8.7

WebVirtMgr (by retspen) is a simple but great libvirt frontend written in python with Django. It currently supports only KVM as hypervisor. However libvirt can be already used to manage other hypervisors (like XEN) and it also supports LXC containers.

Using the container libvirt feature I extended WebVirtMgr, creating a fork, which adds LXC support and other minor improvements (see https://github.com/daniviga/webvirtmgr/commits/master)

LXC support currently has some limitations:

  • The LXC container filesystem must be created manually (this is a libvirt limitation)
  • Even the LXC domain creation isn’t supported right now (you need to create the XML and define the domain manually, virt-install can be used)
  • Web remote console is under development and not yet ready (some work has been made using butterfly)
  • LXC domain deletion doesn’t remove its filesystem
  • Snapshotting is not supported (another libvirt limitation, it can be done manually with LVM or Btrfs)

But basic functions works well:

  • Management of remote hosts (via TCP, SSH, TLS, socket)
  • Start, stop, shutdown, pause
  • Autostart
  • CPU and RAM limits assignment
  • Network interfaces management
  • Clone (only the domain, filesystem must be copied manually)

My WebVirtMgr fork contains also some minor differences and improvements compared to the original:

  • The old connections list page (with a table instead of boxes) has been kept
  • It supports a very basic ACLs system (for both KVM and LXC). With this feature non-admin users can be created (using the django-admin interface) that can only have specific access to a pre-defined set of VMs/LXCs. This means that user “foo“, for example, can only start/stop/shutdown or access the remote console of the VM “my_vm

The installation procedure remains the same as the original project.
