Migrating virtual machines between oversubscribed and undersubscribed compute devices

摘要

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive, at a management device, an instantiation request for a first virtual machine. The code includes code to cause the processor to identify a first compute device at a first time such that the first compute device is undersubscribed at the first time. The code includes code to cause the processor to send an instruction to instantiate the first virtual machine at the compute device, and receive a signal indicating that a boot process associated with the first virtual machine is complete and that the virtual machine is instantiated at the first compute device. The code includes code to cause the processor to send at a second time, a signal to migrate the first virtual machine from the first compute device to a second compute device in response to the boot process being complete.

1. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:
receive an instantiation request for a first virtual machine; identify a first compute device at a first time and in response to the instantiation request, the first compute device implementing an undersubscribed policy at the first time causing a number of all virtual machines provisioned at the first compute device to be no greater than a total number of central processing units at the first compute device; send, after the first time and before a second time, an instruction to instantiate the first virtual machine at the first compute device; receive a signal indicating that a boot process associated with the first virtual machine is complete and that the first virtual machine is instantiated at the first compute device; and send, at the second time, a signal to migrate the first virtual machine from the first compute device to a second compute device implementing an oversubscribed policy in response to the boot process being complete, the second compute device executing a second virtual machine at the second time.
