KVM: VMX: Fake emulate Intel perfctr MSRs
Older linux guests (in this case, 2.6.9) can attempt to
access the performance counter MSRs without a fixup section, and injecting
a GPF kills the guest. Work around by allowing the guest to write those MSRs.
Tested by me on RHEL-4 i386 and x86_64 guests, as well as F-9 guests.
