Abstract

Aspects of the disclosure allocate shares of processing resources or other physical resources among virtual machines (VMs) operating as, for example, virtual desktops on a plurality of host computing devices. Allocations of resources are adjusted based on the user activity, VM activity, and/or application activity detected by an agent executing on each VM. Allocated shares may be boosted, unboosted, or normalized, depending on the type and duration of detected activity, by a resource allocation manager executing on a management server.

Claims

1. A system for resource allocation in a virtualized computing environment, comprising at least one physical computing system hosting a plurality of virtual machines (VMs), the system comprising:

a memory;

a processor;

a plurality of agents, each associated with at least one of the plurality of VMs, that, when executed by the processor, collect activity information about the associated VM;

a module that is stored in the memory and, when executed by the processor, dynamically allocates physical computing resources of the at least one physical computing system amongst the plurality of VMs, each of the plurality of VMs configured to execute a virtual desktop remotely accessible by a user, the dynamic allocation performed by;

monitoring, by the plurality of agents, a state of the virtual desktop of each associated VM to detect activities triggered by an active user session, the detected activities forming at least a portion of the activity information;

comparing the collected activity information to a policy;

in response to the detected activities, automatically modifying, based on the activity information, an allocation of the physical computing resources of the at least one physical computing system to the plurality of VMs.

2. The system of claim 1, further comprising an appliance that is stored on the physical computing system and that is configured, when executed by the processor, to request a change to physical resource allocation for the VMs executing on the physical computing device based on the collected information.

3. The system of claim 1, wherein modifying the allocation of the physical computing resources further comprises at least one of boosting, unboosting, or normalizing the amount of resources allocated to the VM.

4. The system of claim 1, wherein the activity information further comprises information about at least one of user activity, machine activity, or application activity.

5. The system of claim 1, wherein the physical computing resources further comprise at least one of storage priority, graphics protocols, or CPU resources.

6. The system of claim 1, wherein modifying the allocation of the physical computing resources further comprises suspending or resuming fault tolerance operating on the VM by:

monitoring the user and application activity;

upon determining that either the VM or the user are idle based on the monitoring, suspending the operation of fault tolerance on the VM; and

upon determining that either the VM or the user are active based on the monitoring, resuming the operation of fault tolerance on the VM.

7. The system of claim 1, wherein modifying the allocation of the physical resources further comprises defining a storage priority of data packets transmitted by an application by:

upon determining that the application is active and whitelisted, marking any data packets originated by the application as high priority;

upon determining that the application is inactive, marking any data packets originated by the application as low priority;

upon determining that the application is blacklisted, marking any data packets originated by the application as low priority; and

storing the data packets according to the marked priority.

8. The system of claim 1, wherein modifying the allocation of the physical computing resources further comprises suspending or resuming the VM by:

monitoring the user activity and the machine activity;

upon determining that the VM is idle based on the monitored activity, suspending the VM; and

upon determining that either the machine or the user are active based on the monitoring, resuming the operation of the VM.

9. A method for resource allocation in a virtualized computing environment comprising at least one physical computing system hosting a plurality of VMs, the method comprising:

dynamically allocating physical computing resources of the at least one physical computing system amongst the plurality of VMs, each of the plurality of VMs configured to execute a virtual desktop that is remotely accessible by a user, the dynamic allocation including;

receiving reports of monitored activities of the user, the VM of the user, and the applications executed by the VM of the user;

comparing the monitored activities to a policy;

determining, based on the comparison, that one or more of the monitored activities has a higher or lower priority than the other activities; and

in response to the determination, automatically modifying, based on the policy, an allocation of the physical computing resources of the at least one physical computing system to the plurality of VMs.

10. The method of claim 9, wherein the policy is federated by a central console to a resource allocation manager executing on the physical computing system.

11. The method of claim 9, wherein the policy is established by an administrator, in accordance with at least one of a terms of service agreement, a service level agreement (SLA), a quality of service (QoS) agreement, or a contract.

12. The method of claim 9, further comprising:

collecting performance metrics of applications executing on the plurality of VMs; and

dynamically adjusting the policy based on the collected performance metrics.

13. The method of claim 9, wherein upon determining that the monitored activities has ended, normalizing the resources allocated to the VM.

14. The method of claim 9, wherein modifying the allocation of the physical computing resources further comprises adjusting access to a wide area network (WAN) link.

15. The method of claim 9, wherein modifying the allocation of the physical computing resources further comprises:

upon determining that an application executing on the physical computing system is active and whitelisted, improving a graphics priority of the application;

upon determining that an application executing on the physical computing system is inactive, decreasing a graphics priority of the application; and

upon determining that an application executing on the physical computing system is blacklisted, decreasing a graphics priority of the application.

16. The method of claim 15, wherein improving or decreasing the graphics priority further comprises adjusting at least one of encoding, compression, or framerates.

17. A non-transitory computer-readable medium including computer-executable instructions that, when executed by a processor, allocate resources in a virtualized computing environment comprising at least one physical computing system hosting a plurality of VMs, the computer-executable instructions comprising:

dynamically allocating physical computing resources of the at least one physical computing system amongst the plurality of VMs, each of the plurality of VMs configured to execute a virtual desktop that is remotely accessible by a user, the dynamic allocation including;

receiving a monitored state of the virtual desktops instantiated on the plurality of VMs to detect activities triggered by active user sessions with the virtual desktops;

receiving indications of priority corresponding to the detected activities;

determining, based on the monitored state and the received indications of priority, that at least one of the detected activities triggers a policy; and

in response to the determining, automatically modifying, based on the policy, an allocation of the physical computing resources of the at least one physical computing system to the plurality of VMs.

18. The non-transitory computer-readable medium of claim 17, wherein the computer-executable instructions further cause the processor, upon determining that the monitored state indicates an underperforming application, boosting resources associated with the underperforming application.

19. The non-transitory computer-readable medium of claim 17, wherein detecting the activities comprises using an application programming interface (API) to communicate with the virtual desktop.

20. The non-transitory computer-readable medium of claim 17, wherein the policy is defined by an administrator.
