[PATCH 0/2] KVM test: Image copy test v2

[Lucas Meneghel Rodrigues]

This is a respin of Amos's patch for image_copy test. In this
version, small cleanups and consistency fixes were made, specially
with regards to using utils.system instead of functions on the
commands API.

  KVM-test: Add mount utility functions
  KVM-test: Add image_copy subtest to prepare images

[PATCH 2/2] KVM-test: Add image_copy subtest to prepare images

[Lucas Meneghel Rodrigues]

From: Amos Kong <akong@redhat.com>

image_copy is used to copy guests' images from NFS server to test
machines. It takes too much time for installing guests everytime.
You can config NFS server directory in tests_base.cfg.

Changes from v1:
- Make better use of autotest API to control subprocesses
- Do not use hardcoded images location. Instead, use the
final destination of the image that is going to be used
by the other tests anyway.

Amos, FYI, image_copy test commited:

Thanks!
