Dynamic tuning of hypervisor for high-performance virtual machines
A method of dynamically tuning a hypervisor includes detecting that a high-performance virtual machine was launched on the hypervisor. The method further includes, in response to the detecting, modifying, by a processing device, a configuration of the hypervisor to increase performance of the high-performance virtual machine on the hypervisor.
1. A method, comprising:
detecting by a hypervisor that a performance of a first virtual machine launched by the hypervisor is to be increased based on analyzing a workload that is being run on the first virtual machine and resources being used by the first virtual machine;
in response to the detecting, modifying, by a processing device, a configuration of the hypervisor to increase performance of the first virtual machine on the hypervisor,
wherein the configuration of the hypervisor that is modified is associated with a q-depth of a storage adapter of a host of the hypervisor;
detecting that the first virtual machine is no longer active on the hypervisor; and
in response to the detecting that the first virtual machine is no longer active on the hypervisor, modifying the configuration of the hypervisor that is associated with the q-depth of the storage adapter to save power on the hypervisor.
2. The method of claim 1 , wherein the first virtual machine is self-designated as high-performing.
3. The method of claim 1 , wherein the configuration of the hypervisor that is modified is further associated with a power-saving C-state of the hypervisor.
4. The method of claim 3 , wherein modifying the configuration of the hypervisor further comprises disabling the power-saving C-state of the hypervisor.
5. The method of claim 1 , wherein the modifying the configuration of the hypervisor is performed without modifying any configuration of the first virtual machine.
6. The method of claim 1 , wherein the first virtual machine is not designated as a desktop virtual machine or a server virtual machine.
7. A system, comprising:
a memory; and
a processing device, operatively coupled to the memory, to:
detect by a hypervisor that a performance of a first virtual machine launched by the hypervisor is to be increased based on an analysis of a workload that is being run on the first virtual machine and resources being used by the first virtual machine;
in response to the detecting, modify a configuration of the hypervisor to increase performance of the first virtual machine on the hypervisor,
wherein the configuration of the hypervisor that is modified is associated with a q-depth of a storage adapter of a host of the hypervisor;
detect that the first virtual machine is no longer active on the hypervisor; and
in response to the detecting that the first virtual machine is no longer active on the hypervisor, modify the configuration of the hypervisor that is associated with the q-depth of the storage adapter to save power on the hypervisor.
8. The system of claim 7 , wherein the first virtual machine is self-designated as high-performing.
9. The system of claim 7 , wherein the configuration of the hypervisor that is modified is further associated with a power-saving C-state of the hypervisor.
10. The system of claim 9 , wherein to modify the configuration of the hypervisor, the processing device is to further disable the power-saving C-state of the hypervisor.
11. The system of claim 7 , wherein the modifying the configuration of the hypervisor is performed without modifying any configuration of the first virtual machine.
12. The system of claim 7 , wherein the first virtual machine is not designated as a desktop virtual machine or a server virtual machine.
13. A non-transitory computer-readable storage medium including instructions that, when executed by a processing device of a source host system, cause the processing device to:
detect by a hypervisor that a performance of a first virtual machine launched by the hypervisor is to be increased based on an analysis of a workload that is being run on the first virtual machine and resources being used by the first virtual machine;
in response to the detecting, modify, by the processing device, a configuration of the hypervisor to increase performance of the first virtual machine on the hypervisor,
wherein the configuration of the hypervisor that is modified is associated with a q-depth of a storage adapter of a host of the hypervisor;
detect that the first virtual machine is no longer active on the hypervisor; and
in response to the detecting that the first virtual machine is no longer active on the hypervisor, modify the configuration of the hypervisor that is associated with the q-depth of the storage adapter to save power on the hypervisor.
14. The non-transitory computer-readable storage medium of claim 13 , wherein the first virtual machine is self-designated as high-performing.
15. The non-transitory computer-readable storage medium of claim 13 , wherein the configuration of the hypervisor that is modified is further associated with a power-saving C-state of the hypervisor.
16. The non-transitory computer-readable storage medium of claim 15 , wherein to modify the configuration of the hypervisor, the processing device is to further disable the power-saving C-state of the hypervisor.
