intel-pstate-do-not-load-on-VM-that-do-not-report-max-P-state.patch

@@ -0,0 +1,58 @@
+Hi Josh,
+
+Sorry for the slow resopnse you caught me on vacation :-)
+
+I do not have either of these VMs ATM to test against.  The patch below
+should solve the problem though It looks like the VM is returning zero
+for the highest P state (frequency) MSR.  The patch will have the driver refuse 
+to load and the system should fall through to one of the other configured 
+governors/ scaling drivers.
+
+Is it possible for tyou to test the patch below while I try to get a test setup
+put together locally?
+
+Thanks in advance

+     It seems some VMs support the P state MSRs but return zeros. Fail
