…present state Inherently, detecting running under virtualization is hard on some virtualization runtimes. This change attempts to improve that situation by detecting container runtime env vars, and detecting gVisor using /proc/cmdline. Kata Containers cannot be reliably determined using this version of Am I Isolated, but the fallback uptime check test might present a maybe present result, to indicate that signs were detected.
