Abstract: A system and method for reserving resources for a virtual machine to use during failure of an underlying node are disclosed. The system and method include a scheduling module that is configured to reserve resources for the virtual machine on at least one candidate node. To reserve the resources, the scheduling module is configured to identify a list of candidate nodes based upon a qualifier function, rank the candidate nodes based upon a priority function, and determine the candidate nodes that satisfy a high availability threshold. The scheduling module is also configured to select a highest-ranked candidate node that satisfies the high availability threshold and reserve the resources on the highest-ranked candidate node.

Abstract: In one embodiment, a system for migrating virtual machines in a virtualization environment includes a plurality of host machines implementing the virtualization environment and a migration controller. Each of the host machines includes a hypervisor, one or more user virtual machines (UVMs) and a virtual machine controller. The system further implements a virtual disk comprising a plurality of storage devices, the virtual disk being accessible by the virtual machine controllers, which conduct I/O transactions with the virtual disk. The migration controller determines a segment size and, for each host machine, determines a number of required segments for the UVMs running on the host machine. The controller computes a number of reserved segments based on a total number of host machines and a largest one of the numbers of required segments. The reserved segments are then assigned among the plurality of host machines.
