Re: [PATCH 0/5] KVM: VMX: Drop MTRR virtualization, honor guest PAT

[Yan Zhao]

Xiangfei found out an failure in kvm unit test rdtsc_vmexit_diff_test
with below error log:
"FAIL: RDTSC to VM-exit delta too high in 100 of 100 iterations, last = 902
FAIL: Guest didn't run to completion."

Fixed it by adding below lines in the unit test rdtsc_vmexit_diff_test before
enter guest in my side.
vmcs_write(HOST_PAT, 0x6);
vmcs_clear_bits(EXI_CONTROLS, EXI_SAVE_PAT);
vmcs_set_bits(EXI_CONTROLS, EXI_LOAD_PAT);
