RAPID CREATION AND RECONFIGURATION OF VIRTUAL MACHINES ON HOSTS

摘要

A rapid virtual machine (VM) cloning technique is provided that creates cloned VMs on hosts from multiple source VMs, rather than a single source VM that may otherwise be a bottleneck. The described technique selects particular hosts, disposed in particular racks, on which to create VM clones in a dynamic manner that reduces total deployment time for the plurality of VMs. A rapid VM reconfiguration technique is also provided that reduces the time spent reconfiguring the provisioned VMs for use in a distributed computing application.

1. A method for provisioning a plurality of virtual machines (VMs) on a plurality of hosts, the method comprising:
selecting a source virtual machine (VM) from a pool of VMs available to be cloned, wherein the selected source VM is on a source host; determining, for each of a plurality of hosts including the source host, a time to create a predetermined target number of VMs for the respective host on the respective host; selecting a target host from the plurality of hosts having a longest respective time to create the predetermined target number of VMs for the respective host; cloning the source VM to create a second VM on the selected target host; and adding the second VM to the pool of VMs available to be cloned.
