You mean that the qcow2 file size will not increase when "savevm" commnad is issued after "delvm". Namely, the qcow2 file size is almost same when I take a snapshot after delete previous snapshot image. > QEMU should also convert the unused clusters to "holes" in the file > system, but it doesn't do that yet. I hope a qcow2 file is reduced automatically when a snapshot is deleted. > > Is there any method to reduce the qcow2 file size when I delete a snapshot > > image? > > should I "convert" the qcow2 file? > > I'm not sure what convert does if you have internal snapshots. > > Paolo ------ suzaki
