Having said that, there is probably a bug in Horizon since it's 
defaulting to vda for the device name when booting from volume.

The libvirt driver in nova ignores the requested device name in boot 
from volume / volume attach requests since Liberty [1]. It's best to let 
the virt driver in nova pick the device name, you can get the mountpoint 
via the volume attachment later after the volume's status is 'in-use'.
