With this additional patch (below), this passes all qemu-iotests for qcow2.

Subject: [PATCH v10 3/2 1/1] qemu-iotests: exclude vxhs from image creation
 via protocol

The protocol VXHS does not support image creation.  Some tests expect
to be able to create images through the protocol.  Exclude VXHS from
these tests.
