The "load IA32_PERF_GLOBAL_CTRL" bit for VM-entry and VM-exit should only be exposed to the guest if IA32_PERF_GLOBAL_CTRL is a valid MSR. Create a new helper to allow pmu_refresh() to update the VM-Entry and VM-Exit controls to ensure PMU values are initialized when performing the is_valid_msr() check.
