VMXON is created per VMM, not per logical processor, right? Intel spec says as below: Before entering VMX operation, the host VMM allocates a VMXON region. A VMM can host several virtual machines and have many VMCSs active under its management. A unique VMCS region is required for each virtual machine; a VMXON region is ^^^ if each vm has multiple logical processor, A unique VMCS region is required for each logical processor. required for the VMM itself. > VMCS region is created for each guest vcpu and used both by the hypervisor and the processor.
