61 * According to Section 21.10.4 "Software Access to Related Structures",
62 * changes to data structures pointed to by the VMCS must be made only when
63 * there is no logical processor with a current VMCS that points to the
64 * data structure.
65 *
66 * This pretty much limits us to configuring the MSR bitmap before VMCS
67 * initialization for SMP VMs. Unless of course we do it the hard way - which
68 * would involve some form of synchronization between the vcpus to vmclear
69 * all VMCSs' that point to the bitmap.
