...> from > physical and virtual devices to guest memory. maybe clearer to call controlling 'virtual' DMA access since we're essentially doing DMA virtualization here. Otherwise I read it a bit confusing since DMA accesses from physical device should be controlled by pIOMMU. > GVA, GPA, HVA, HPA > Guest/Host Virtual/Physical Address > IOVA I/O Virtual Address, the address accessed by a device doing DMA > through an IOMMU. In the context of a guest OS, IOVA is GVA. This statement is not accurate. For kernel DMA protection, it is per-device standalone address spac...

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
