Well, the --availability-zone option can be given a host name separated 
from an optional actual availability zone identifier by a colon:

nova boot .. --availability-zone :hostname ...

But specifying a specific host rather than just an availability zone 
requires the project to have forced_host (or is it force_host?) 
capabilities.  You could, perhaps, define the two computes to be 
separate availability zones to work around that.
