Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus makes a first determination whether a load metric of a first hypervisor is in a first predetermined relationship with a first threshold. The first hypervisor is one of a plurality of hypervisors of a VDI system. The apparatus also makes a second determination whether an available capacity of a second hypervisor is able to run virtual desktops of the first hypervisor when the load metric of the first hypervisor is determined to be in the predetermined relationship with the first threshold. The first hypervisor migrates virtual desktops of the first hypervisor to the second hypervisor when the available capacity of the second hypervisor of the plurality of hypervisors is determined to be able to run virtual desktops of the first hypervisor. The apparatus also powers off the first hypervisor.

First claim

What is claimed is:

1 . A method of managing virtual desktops of a virtual desktop infrastructure (VDI) system, comprising:
making a first determination whether a load metric of a first hypervisor is in a first predetermined relationship with a first threshold, wherein the first hypervisor is one of a plurality of hypervisors of the VDI system; making a second determination whether an available capacity of a second hypervisor of the plurality of hypervisors is able to run virtual desktops of the first hypervisor when the load metric of the first hypervisor is determined to be in the first predetermined relationship with the first threshold; request the first hypervisor to migrate virtual desktops of the first hypervisor to the second hypervisor when the available capacity of the second hypervisor of the plurality of hypervisors is determined to be able to run virtual desktops of the first hypervisor; and powering off the first hypervisor.

2 . The method of claim 1 , wherein the first threshold is at least one of a number threshold of virtual machines running on the first hypervisor, a load threshold of a processor of the first hypervisor, a usage threshold of a memory of the first hypervisor, and an activity threshold of a disk of the first hypervisor.

3 . The method of claim 2 , further comprising:
determining a load of the processor of the first hypervisor, wherein the first determination includes determining whether the load is below the load threshold.

4 . The method of claim 2 , further comprising:
determining a usage of the memory of the first hypervisor, wherein the first determination includes determining whether the usage is above the usage threshold.

5 . The method of claim 2 , further comprising:
determining a count of read or write activities performed by the disk of the first hypervisor, wherein the first determination includes determining whether the count is above the activity threshold.

6 . The method of claim 1 , further comprising:
making a third determination whether a load metric of the second hypervisor is above a second threshold and below a third threshold, wherein the second determination is made in response to that the load metric of the second hypervisor is determined to be above the second threshold and below the third threshold.

7 . The method of claim 1 , further comprising:
determining a respective load metric of each of the plurality of hypervisors; comparing the load metric of the first hypervisor with the respective load metric of each of the other hypervisors of the plurality of hypervisors; and selecting the first hypervisor to make the first determination based on a result of the comparison.

8 . The method of claim 1 , further comprising:
making a fourth determination whether the load metric of the first hypervisor is in a second predetermined relationship with a fourth threshold, when the load metric is not in the first predetermined relationship with the first threshold; powering on a third hypervisor when the load metric of the first hypervisor is in the second predetermined relationship with the fourth threshold and the third hypervisor is not powered on; and requesting the first hypervisor to migrate one or more of virtual desktops of the first hypervisor to the third hypervisor.

9 . An apparatus for managing virtual desktops of a virtual desktop infrastructure (VDI) system, comprising:
a memory; and at least one processor coupled to the memory and configured to:
make a first determination whether a load metric of a first hypervisor is in a first predetermined relationship with a first threshold, wherein the first hypervisor is one of a plurality of hypervisors of the VDI system;
make a second determination whether an available capacity of a second hypervisor of the plurality of hypervisors is able to run virtual desktops of the first hypervisor when the load metric of the first hypervisor is determined to be in the first predetermined relationship with the first threshold;
request the first hypervisor to migrate virtual desktops of the first hypervisor to the second hypervisor when the available capacity of the second hypervisor of the plurality of hypervisors is determined to be able to run virtual desktops of the first hypervisor; and
power off the first hypervisor.

10 . The apparatus of claim 9 , wherein the first threshold is at least one of a number threshold of virtual machines running on the first hypervisor, a load threshold of a processor of the first hypervisor, a usage threshold of a memory of the first hypervisor, and an activity threshold of a disk of the first hypervisor.

11 . The apparatus of claim 10 , wherein the at least one processor is further configured to:
determine a load of the processor of the first hypervisor, wherein the first determination includes determining whether the load is below the load threshold.

12 . The apparatus of claim 10 , wherein the at least one processor is further configured to:
determine a usage of the memory of the first hypervisor, wherein the first determination includes determining whether the usage is above the usage threshold.

13 . The apparatus of claim 10 , wherein the at least one processor is further configured to:
determine a count of read or write activities performed by the disk of the first hypervisor, wherein the first determination includes determining whether the count is above the activity threshold.

14 . The apparatus of claim 9 , wherein the at least one processor is further configured to:
make a third determination whether a load metric of the second hypervisor is above a second threshold and below a third threshold, wherein the second determination is made in response to that the load metric of the second hypervisor is determined to be above the second threshold and below the third threshold.

15 . The apparatus of claim 9 , wherein the at least one processor is further configured to:
determine a respective load metric of each of the plurality of hypervisors; compare the load metric of the first hypervisor with the respective load metric of each of the other hypervisors of the plurality of hypervisors; and select the first hypervisor to make the first determination based on a result of the comparison.

16 . The apparatus of claim 9 , wherein the at least one processor is further configured to:
make a fourth determination whether the load metric of the first hypervisor is in a second predetermined relationship with a fourth threshold, when the load metric is not in the first predetermined relationship with the first threshold; power on a third hypervisor when the load metric of the first hypervisor is in the second predetermined relationship with the fourth threshold and the third hypervisor is not powered on; and request the first hypervisor to migrate one or more of virtual desktops of the first hypervisor to the third hypervisor.

17 . A computer-readable medium storing computer executable code for operating an apparatus managing virtual desktops of a virtual desktop infrastructure (VDI) system, comprising code to:
make a first determination whether a load metric of a first hypervisor is in a first predetermined relationship with a first threshold, wherein the first hypervisor is one of a plurality of hypervisors of the VDI system; make a second determination whether an available capacity of a second hypervisor of the plurality of hypervisors is able to run virtual desktops of the first hypervisor when the load metric of the first hypervisor is determined to be in the first predetermined
