Commands tried with qemu-0.10.0-1ubuntu1:
$ mkdir unlikely_subdir
$ cd unlikely_subdir
$ qemu-img create -f qcow2 backing.img 10
Formatting 'backing.img', fmt=qcow2, size=10 kB
$ qemu-img create -f qcow2 -b ../unlikely_subdir/backing.img main.img 10
Formatting 'main.img', fmt=qcow2, backing_file=../unlikely_subdir/backing.img,
size=10 kB
$ cd ..
$ qemu-img info unlikely_subdir/main.img
image: unlikely_subdir/main.img
file format: qcow2
virtual size: 10K (10240 bytes)
disk size: 16K
cluster_size: 4096
highest_alloc: 16384
backing file: ../unlikely_subdir/backing.img (actual path:
unlikely_subdir/../unlikely_subdir/backing.img)
See especially the "actual path" line.
$ mv unlikely_subdir other_subdir
$ ls -l other_subdir
total 32
-rw-r--r-- 1 jamie jamie 16384 2009-07-15 21:59 backing.img
-rw-r--r-- 1 jamie jamie 16384 2009-07-15 21:59 main.img
$ qemu-img info other_subdir/main.img
qemu-img: Could not open 'other_subdir/main.img'
What an unhelpful error message... There isn't even a way to find out
the backing file path which the tool is looking for.

Sorry, I don't know anything about any QEMU test suites.
