[Qemu-discuss] qemu-img asserting in Travis CI environment

[Michael Henriksen]

Hi All,

I am seeing the following assertion when running qemu-img as part of a test
in Travis CI:

qemu-img: /builddir/build/BUILD/qemu-2.11.2/util/async.c:481: aio_co_enter:
Assertion `self != co' failed.

The command looks like this:

qemu-img convert -f qcow2 -O raw 'json: {"file.driver": "http", "file.url":
"http://localhost:8080/cirros-qcow2.img";, "file.timeout":
3600}' /tmp/cirros-test-good

Sometimes, qemu-img executes successfully, but most of the time, it fails.
Any idea what may be causing this assertion?  Travis CI is a free service,
that I assume has certain resource constraints.

Your help will be appreciated!

Mike
