[Qemu-devel] [PATCH 7/7] iotests: Disable 126 for some vmdk subformats

[Max Reitz <mreitz@redhat.com>]

Several vmdk subformats do not work with iotest 126, so disable them.

(twoGbMaxExtentSparse actually should work, but fixing that is a bit
difficult.  The problem is that the vmdk descriptor file will contain a
referenc to "image:base.vmdk", which the block layer cannot open because
it does not know the protocol "image".  This is not trivial to solve,
because I suppose real protocols like "http://" should be supported.
Making vmdk treat all paths with a potential protocol prefix that the
block layer does not recognize as plain files seems a bit weird,
though.  Ignoring this problem does not seem too bad.)
