Node? Meaning dom0? Or the guest? Are you using dom0_mem=max:X argument?
Node means the physical machine. I was not sure to call it as dom0.
dom0 in this case has default 750 MB RAM.

Which PV driver is this? Is this with the other ones: GPL one, Citrix, Novell, and
Oracle as well?
This is Citrix PV driver. XCP 1.1 and PV drivers are 1.1 version.
