qemu-img: symbol lookup error: qemu-img: undefined symbol: rbd_aio_discard

[Ryan Beisner]

On Precise or Trusty:

$ qemu-img --help
qemu-img: symbol lookup error: qemu-img: undefined symbol: rbd_aio_discard

$ qemu-img
qemu-img: symbol lookup error: qemu-img: undefined symbol: rbd_aio_discard

$ dpkg-query --show qemu-utils
qemu-utils 2.0.0+dfsg-2ubuntu1.6~cloud0

Workaround:
$ sudo apt-get install librbd1

Then qemu-img works.

cinder (next and stable) charm amulet tests fail with: vol create failed - from glance img

Liam mentioned he'd take a look as it sounded familiar.

The log mentions "qemu-img is not installed and image is of type qcow2.
Only RAW images can be used if qemu-img is not installed"

Here are some more details from /var/log/cinder/cinder-volume.log:

Even with qemu-img installed, the test fails. This appears to be due to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=680307

Please see this demonstration of the busted qemu-img on Precise:
