Abstract: An opportunistic hypervisor determines that a guest virtual machine of a virtualization host has voluntarily released control of a physical processor. The hypervisor uses the released processor to identify and initiate a virtualization management task which has not been completed. In response to determining that at least a portion of the task has been performed, the hypervisor enters a quiescent state, releasing the physical processor to enable resumption of the guest virtual machine.

Abstract: An offloaded virtualization management component of a virtualization host receives an indication from a hypervisor of a portion of main memory of the host for which memory allocation decisions are not to be performed by the hypervisor. The offloaded virtualization management component assigns a subset of the portion to a particular guest virtual machine and provides an indication of the subset to the hypervisor.
