Issue: test.pythoninfo: Detect if running in a container or in a virtual machine (VM) #152680

vstinner · 2026-06-30T11:32:21Z

Example on "Ubuntu / build and test (ubuntu-24.04)":

system.boot_id: 7eedccbd-ab3e-48f4-a3f5-eb198989311d
system.in_container: microsoft
system.machine_id: b9d4e40b90bc4dcb974f6d60e5fb946e
system.uptime: 0:02:16

system.in_container: microsoft: Microsoft Hyper-V hypervisor is detected.

Log also the "CI" and "container" environment variable.

* Fix ver command * Fix kern.hv_vmm_present test * Log also IMAGE_OS_VERSION env var. * Remove debug messages

vstinner · 2026-06-30T13:44:57Z

Example on macOS / build and test (macos-26):

system.hardware: VirtualMac2,1
system.uptime: 0:05:19
system.virt: run in a VM (kern.hv_vmm_present is 1)

Virtualization is now detected and the hardware model is also logged.
