How do I restore a VM with a non 64k block disk?

[paul20]

How do I restore a VM with a non 64k block disk? It gives me this error:
(process:21762): ERROR : 19:26:15.945: restore failed - got wrong block address - write beyond end

I've also tried vma extract and it gives the same error. Is there a way to force restoring it or making the disk the correct size, so it successfully restores it?
