Comment 4 for bug 1012595

They have been removed from the pool.

Before June 12, a flaw in hpcloud machines was causing tests to pass without being run. That's when we worked around that issue. So the failures could have been happening before then, and possibly since the time we switched to precise images.

Since devstack is configuring bare QEMU virtualization, it's not clear to me what kind of support could be missing to cause that.
