...seems i have exactly the same trouble, doing some more tests seems
that timeout does not happen if i use RAW, but only for QCOW; but in
the temporary NFS storage i've not space for the RAW disk...

In this link someone say:

	you can manually create the image (with qemu-img create and then rescan to reference it as unused volume in the configuration

but i need to move the disk, not create it...
