Subject: iotests: More options for VM.add_drive()
X-Git-Tag: TizenStudio_2.0_p2.3.2~120^2~1^2~214^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e4922535b6479c7a2fa6b14b0148c6ae4fcc003;p=sdk%2Femulator%2Fqemu.git

iotests: More options for VM.add_drive()

This patch allows specifying the interface to be used for the drive, and
makes specifying a path optional (if the path is None, the "file" option
will be omitted, thus creating an empty drive).
