[PULL 02/25] tests/vm: Allow to set qemu-img path |
Date: |

From: Wainer dos Santos Moschetta <address@hidden>
By default VM build test use qemu-img from system's PATH to
create the image disk. Due the lack of qemu-img on the system
or the desire to simply use a version built with QEMU, it would
be nice to allow one to set its path. So this patch makes that
possible by reading the path to qemu-img from QEMU_IMG if set,
otherwise it fallback to default behavior.

+QEMU binaries
+-------------
By default, qemu-system-x86_64 is searched in $PATH to run the guest. If there
isn't one, or if it is older than 2.10, the test won't work. In this case,
provide the QEMU binary in env var: ``QEMU=/path/to/qemu-2.10+``.
+Likewise the path to qemu-img can be set in QEMU_IMG environment variable.
