[Powertop] Excessive CPU speeds shown in VM

Inside a VirtualBox VM, powertop-2.0 shows: Package | Core | CPU 0 | | Actual 9223372036854.8 GHz Idle 100.0% | Idle 100.0% | Idle 100.0% | Core | CPU 1 | | Actual 9223372036854.8 GHz | Idle 100.0% | Idle 100.0% (powertop-1.13 says "Detailed C-state information is not P-states (frequencies)") I'd certainly love to have such a speedy CPU, though I wonder if the laws of physics still hold at 9.2 YHz. lscpu knows more: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 26 Stepping: 4 CPU MHz: 2663.279 BogoMIPS: 5326.55 L1d cache: 32K L1d cache: 32K L2d cache: 6144K NUMA node0 CPU(s): 0,1
