Cinder unit tests fail on virtio VMs

[Dirk Mueller]

Hi,

when using an udev with this commit:

http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=9fc643a41490dd891d42e2e3885db183809d0ffc

there are no /dev/disk/by-path/ symlinks available for virtio devices, which causes tests to fail:

08:02:26 Traceback (most recent call last):
08:02:26 File "/var/lib/openstack-cinder-test/cinder/tests/test_brick_initiator.py", line 263, in test_connect_volume

08:02:26 OSError: [Errno 2] No such file or directory: '/dev/disk/by-path/'
