Non-hint PAC instructions will generate a SIGILL even if PAC has never been enabled in the guest. This is circumvented by enabling PAC in the guest, but setting all of the PAC keys to zero which effectively makes all PAC instructions no-ops, as was originally the intention with disabling PAC in KVM in the first place.
