VMM Responsibility

[maniyuvaraj]

Hi Friends,

I need clarification regarding VMM responsibility when the Monitor execution mode changes..

The VMM responsibility when Monitor Execution Mode in Software Visualization i.e the Hardware doesn't support the VT and VMM responsibility when Hardware Visualization Mode i.e VT enabled Hardware.

As per my understating in Software Visualization Mode the VMM will running on Ring 0 and perform the Binary Translation but not sure VMM responsibility in Hardware Visualization Mode.

Please clarify in detailed.. Thanks...

WIth hardware-assisted virtualization, the VMM manages the VMCS and handles VM-exits, generally emulating one or more instructions before returning to guest mode.  It forwards external interrupts to the host OS. It manages the mapping of guest physical addresses to host physical addresses.  It virtualizes the local APIC and IOAPIC.
