That isn't going to work - the Anaconda installer will only look for
block devices, not partitions. Having partitions which are not a part
of a block device is a Xen driver hack which is not supportable. If 
you want to have 3 completely separate volumes in the host be visible
as 3 separate volumes inside the guest, then you can export them as 
individual devices 'xdva', 'xvdb', 'xvdc'. Then in Anaconda create a 
single partition on each one, eg  xvda1, xvdb1, xvdc1  which you can 
then map to /, /var and swap respectively.
