Try:
disks = ['phy:sdb,sdb,w']

If that doesn't work (I can't remember if exporting whole disks works) then 
export the partitions individually:
disks = [ 'phy:sdb1,sdb1,w', 'phy:sdb2,sdb2,w', 'phy:sdb3,sdb3,w' ... and so 
on.

This is a more advanced feature of the comfig files, intended to allow you to 
pass an additional variable "vmid" into "xm create" and automatically 
generate the disk, network, etc settings for several domains using a single 
config file.  It's rarely used and for your configuration you should probably 
ignore it.
