Module lease_scheduler

source code

This module provides the main classes for Haizea's lease scheduler, particularly the LeaseScheduler class. This module does *not* contain VM scheduling code (i.e., the code that decides what physical hosts a VM should be mapped to), which is located in the vm_scheduler module. Lease preparation code (e.g., image transfer scheduling) is located in the preparation_schedulers package. In fact, the main purpose of the lease schedule is to orchestrate these preparation and VM schedulers.

This module also includes a Queue class and a LeaseTable class, which are used by the lease scheduler.
