Anyone has suggestion?
When the host kernel before this commit 2e8cd7a3b828 ("kvm: x86: limit the
maximum number of vPMU
fixed counters to 3") on icelake microarchitecture and newer, execute cpuid in
the Guest:
Architecture Performance Monitoring Features (0xa/edx):
number of fixed counters = 0x4 (4)
This is not inconsistent with num_architectural_pmu_fixed_counters in QEMU.
