Max Reitz 908b30164b iotests: Allow 147 to be run concurrently
To do this, we need to allow creating the NBD server on various ports
instead of a single one (which may not even work if you run just one
instance, because something entirely else might be using that port).

So we just pick a random port in [32768, 32768 + 1024) and try to create
a server there.  If that fails, we just retry until something sticks.

For the IPv6 test, we need a different range, though (just above that
one).  This is because "localhost" resolves to both 127.0.0.1 and ::1.
This means that if you bind to it, it will bind to both, if possible, or
just one if the other is already in use.  Therefore, if the IPv6 test
has already taken [::1]:some_port and we then try to take
localhost:some_port, that will work -- only the second server will be
bound to 127.0.0.1:some_port alone and not [::1]:some_port in addition.
So we have two different servers on the same port, one for IPv4 and one
for IPv6.

But when we then try to connect to the server through
localhost:some_port, we will always end up at the IPv6 one (as long as
it is up), and this may not be the one we want.

Thus, we must make sure not to create an IPv6-only NBD server on the
same port as a normal "dual-stack" NBD server -- which is done by using
distinct port ranges, as explained above.

=== This is the QEMU I/O test suite ===

* Intro

This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries.  This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.

* Usage

Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format.  The output of ./check -h explains
additional options to test further image formats or I/O methods.

* Feedback and patches

Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@nongnu.org with a CC:
to qemu-block@nongnu.org.
