UMLMON is a complete run time environment for User Mode Linux. There is a separate monitor daemon for every VM.
UMLMON project creates the run time environment and starts the VM by executing the UML kernel. The daemon also determines the arguments that are passed to the UML kernel, and includes special support to set up arguments for memory size, virtual disks, virtual network interfaces, and console channels in a convenient way.
UMLMON also includes routines to do certain administration tasks like the creation of disks.
The team UMLMON + UML can be applied in the following areas:
· Server consolidation: Improve the utilization of server hardware, and ease the operation of servers.
· Virtual security zones: Instead of building demilitarized zones (DMZ) with real hardware, it is a cost-effective alternative to set up purely virtual DMZs on a single host.
· Virtual hosting: A cheap version of server hosting is virtual hosting; instead of leasing real computers to customers, virtual machines are used.
· Laboratory nets: By using virtual machines it is possible to build cheap laboratory nets, e.g. to test software in real network environments.
· Training environments: One can use virtual machines for Linux trainings where participants can get true administrator's priviledges without any risks.
What's New in This Release:
· This release no longer call the problematic glibc function getgrouplist, which is often broken (symptom: segmentation fault immediately after starting umlmon).
