[Qemu-devel] [PATCH RFC v9 1/7] qemu-iotests: qemu machine type support

[Bo Tu <tubo@linux.vnet.ibm.com>]

From: Xiao Guang Chen <chenxg@linux.vnet.ibm.com>

This patch adds qemu machine type support to the io test suite.
Based on the qemu default machine type and alias of the default machine type
the reference output file can now vary from the default to a machine specific
output file if necessary. When using a machine specific reference file if the
default machine has an alias then use the alias as the output file name
otherwise use the default machine name as the output file name.
