List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Michael Roth , Olga Krishtal , qemu-devel@nongnu.org, "Denis V. Lunev" From: Olga Krishtal We need qmp_quest_get_fsinfo togather with vss-provider, which works with volumes. The call to this function is implemented via FindFirst/NextVolumes. Moreover volumes in Windows OS are filesystem unit, so it will be more effective to work with them rather with devices. Signed-off-by: Olga Krishtal Signed-off-by: Denis V.
