**NotImplementedError: format conversion from 'raw' not implemented**

Hi,

Just trying your script, configured.. and trying to migrate a simple VM from one cluster to another:

**NotImplementedError: format conversion from 'raw' not implemented**

Can some checks be implemented before doing any work ? - this transfer left me with a orphaned vm on destination and a stopped and renamed VM on source.

Thank you

Lots of checks are implemented, but apparently not the one that you're running into..

I agree that it's annoying to find out that it isn't implemented when at 90% of the work. That shouldn't happen.

What filesystem are you converting to?

[Walter Doekes]

I suspect this might fix your troubles:

         rel_path = os.path.join(
             str(dst_id), '{}.{}'.format(dst_name, dst_format))

But I haven't tested this. We've only used ZFS target filesystems for a while now.

@brosky : if you could test this and confirm whether it works for you, that'd be nice.
