Noteshttps://docs.cloud.google.com/compute/docs/instances/bare-metal-instances

  • Bare metal instances provide direct access to the host server's CPU and memory, without Compute Engine's hypervisor in the middle. Bare metal instances also expose all CPU performance counters and built in CPU accelerators
  • NA: The test sponsor attests, as of date of publication, that CVE-2017-5754 (Meltdown) is mitigated in the system as tested and documented.
  • Yes: The test sponsor attests, as of date of publication, that CVE-2017-5753 (Spectre variant 1) is mitigated in the system as tested and documented.
  • Yes: The test sponsor attests, as of date of publication, that CVE-2017-5715 (Spectre variant 2) is mitigated in the system as tested and documented.
