Invalidate cache by scanning and flushing the whole guest memory is inefficient which might cause long execution time for WBINVD emulation. A long execution in hypervisor might cause a vCPU stuck phenomenon what impact Windows Guest booting. This patch introduce a workaround method that pausing all other vCPUs in the same VM when do wbinvd emulation.
