Hi again, so after a test again.
i try the import again with 320GB, the image is 239GB and it works.

the vm-server has local storage and nfs storage , the local storage is 1,5TB .
I imported the image to the local storage of the vm-server and now it works.

Thanks to the clearvm support.

the setup is a clearvm server with 1500GB harddrive and 4GB RAM
the server is starting from the harddrive

So i try again:

the same after 2times
