None of them are directly required by Xen.  They may be required by other 
components in your system (particularly in the case of haldaemon, I would 
guess).  Hal does all sorts of stuff involving hotplugging of devices, etc 
that I'm not very clear on.  Portmap is, I think, something to do with NFS, 
xfs is the X font server - I'm not sure what it does but I doubt you need 
that on a typically dom0 either.

You could try switching them off and seeing if anything breaks ;-)

Cheers,
Mark
