2 unit test failures with fresh AIO isntall (test_COPY and test_copy_from)

I am getting the following two failures when running tox on my dev branch so tried a freshly installed VM and SWAIO following the directions in the 1.8.1 dev docs and hit the same issue when running unittests as part of the install. In the first case I'm using 4 10GB virtual disks with mount points per the AIO docs and in the latter case I'm using a 3GB loopback device. One of my co-workers does not see this so either there's something in my env or, more likely, user error to blame here. Curious if anyone has run into this before and can save be tracking down what I'm doing wrong... thanks in advance -Paul
