There is no relationship between them:
VMXON region is created per logical processor and used by it for VMX ops.
VMCS region is created for eac
For example migration between Westmere and Nehelem hosts.
The patch fixes the guest segments similar to enter_rmode function.

For example migration between Westmere and Nehelem hosts.
The code that fixes the segments for real mode guest was moved from enter_rmode
to vmx_set_segments. enter_rmode calls vmx_set_segments for each segment.
