Abstract
A method and system for managing multiple queues providing a communication path between a virtual machine and a hypervisor in a virtual machine system. The multiple queues are bundled together and identified on a polled list. When one of the queues on the polled list is used to communicate a request from the virtual machine to the hypervisor, a virtual machine exit is performed and a virtual machine exit is disabled for all of the queues on the polled list. The queues on the polled list are assigned to an initial host CPU to service requests from the virtual machine. If a particular queue on the polled list experiences a load that exceeds a load threshold, the particular queue is removed from the polled list and assigned to a different host CPU.
