This is expected; the Hypervisor setup for 126.96.36.199/DRIVE Software 8.0 was 8.0 shared cores across all the VMs, where 188.8.131.52/DRIVE Software 9.0 and later have 6 dedicated cores for the guest OS, and the remaining two shared for the non-guest VMs. This is to give more predictable performance to the guest VM by eliminating any interference from the Foundation Service VMs.

When you run tegrastats on Linux devices, it prints statistics to stdout.
