xscontainer is the back-end of XenServer's Container Management feature.
xscontainer has three main entry points: * src/xscontainer-monitor Watches DomUs on the same host, if they are registered for container management. Responsible for keeping various fields in vm:other_config up to date. * src/xscontainer-prepare-vm Runs inside Dom0 and prepares Ubuntu 14.04, RHEL/CentOS/OEL/7 DOMUs for container management. * src/overlay/etc/xapi.d/plugins/xscontainer The primary entry point for XenCenter and other components to interact with xscontainer directly.
