VMX Exit Control fields

EXIT_CONTROLS:
This field is used by the processor during a vmexit. This is a 32-bit field (just like the entry controls) but only 2 bits are defined:
Bit 9 – Host address space – This value is loaded to EFER.LME and CS.L on a vmexit.
Bit 15 – Acknowledge Interrupt on Exit – If there is a vmexit due to interrupt this bit determines whether the interrupt is acknowledged or not. The interrupt vector is recorded in the vmcs.
All other bits are reserved. They are either 0s or 1s as determined by the EXIT_CTLS_MSR (msr 0x483).

EXIT_CONTROL FOR MSR:
This is exactly similar to ENTRY_CONTROL FOR MSR. The only difference is in the vmcs encodings . They are tabulated below:

EXIT_MSR_STORE_ADDR EQU 0x2006
EXIT_MSR_STORE_COUNT EQU 0x400E
The Guest MSRS are saved in the MSR store area during a vmexit. On a subsequent VMEntry, these MSRS will be loaded from the same area.

EXIT_MSR_LOAD_ADDR EQU 0x2008
EXIT_MSR_LOAD_COUNT EQU 0x4010
The Host MSRs are loaded from the physical address specified in EXIT_MSR_LOAD_ADDR.
The format of the msr-load/msr-store areas is exactly similar to the msr-load area that is used for vmentry.
