[0/4] python/qemu: New accel module and improvements

Message

Wainer dos Santos Moschetta Nov. 15, 2019, 6:08 p.m. UTC

On commit abf0bf998dcb John Snow moved some code out of __init__.py
to machine.py. kvm_available() remained in though. So on patch 01
I continue his work by creating a home for that method (the new
'accel' module). Honestly I was unsure about whether move the code
to any existing module or make a new, but since I am adding more
methods related with accelerators then I thought they would 
deserve a module.

The patches 02-04 introduce new helpers and make improvements. Later
I intend to use those methods on the acceptance tests such as
to automatically set the accelerator in QEMUMachine VM via Avocado
tags, and skip the test if the accelerator is not available.

Git:
 - Tree: https://github.com/wainersm/qemu
 - Branch: python_accel

CI:
 - Travis (FAIL): https://travis-ci.org/wainersm/qemu/builds/612382935
   Non-related fail due build timeout

Wainer dos Santos Moschetta (4):
  python/qemu: Move kvm_available() to its own module
  python/qemu: accel: Add list_accel() method
  python/qemu: accel: Strengthen kvm_available() checks
  python/qemu: accel: Add tcg_available() method

No more comment that what Alex said, I'd move the logging import in 
patch #2 where you use LOG.
With Alex comment fixed:
