Set Default CPU Quota

CPU quota is a percentage value limiting maximum VS CPU load on a compute resource. CPU quota functionality allows limiting CPU usage for the particular virtual server in order to avoid abuse usage which is affecting all virtual servers on the KVM compute resource. 

  • This option is available for the users under administrator's role. Make sure you have enabled Manage CPU quota permission first.
  • This feature is available only for KVM compute resources.
  • Before you enable CPU quota, its value is set to unlimited for all the VSs on this compute resource.


You can set the default value of CPU quota on the compute resource level and edit the custom value on the virtual server level.
