[SOLVED] Import/convert/export raw images to ZFS volume

Hi, I just installed PVE 3.4 and since I had a harddisk failure I took the chance to directly set it up using the new ZFS support. Installation went just fine and everything works as expected. Only I am not able to move my old qcow2 images to the new ZFS partition.

The ZFS partition is mounted as /zfs01 but if I create a new VM there are no files visible on that partition that I could substitute.

I found out that a newly created VM will become a ZFS volume that I can see with

I already converted my images to raw but now I have no clue how I am supposed to create a ZFS volume from my raw image.
The other way around would also be very interesting, how do I create an e.g. qcow2 from a ZFS volume.

Any help is highly appreciated.
Thanks in advance.
