This just means that the Dom0 starts with 2 gigs of ram.   it can still baloon
down to something smaller.   the value it won't baloon below is controlled
by dom0-min-mem  in /etc/xen/xend-config.sxp.  Set that to the minimum amount
of ram you want the Dom0 to have.  (personally I always set that to the same
value as dom0_mem.  For me, usually 512M works ok)
