An internal snapshot of a VM requires that the VM has at least one disk using a QCOW2 volume or similar. The memory state is saved in that image. Your VM has only a RAW disk image and thus it can't be used for internal snapshot. You can either use an external snapshot (the memory image is stored separately), but the support for external snapshots isn't finished yet (they can't be reverted automatically). The second option is to convert your VM to a qcow2 image file..
