[Qemu-devel] [-prfix=PATCH v2 RFC 2/6] qemu-iotests: qemu machine type support

[Xiao Guang Chen <chenxg@linux.vnet.ibm.com>]

From: Mao Chuan Li <maochuan@linux.vnet.ibm.com>

This patch adds qemu machine type support to the io test suite. Based on
the qemu default machine type the reference output file can now vary
from the default to a machine specific output file if necessary. That
shall allow all platforms to use this test suite.
