We tested a wide range of memory parameters for the Citrix PV drivers
on XenServer. I just asked the guy in charge of that, and he said
that they were able to reliably boot w2k8x32 with memory=128MiB and
maxmem=1024MiB.
I know we had to do make some changes to move the balloon driver
allocation further back in the boot process to make that happen; but
I'm not familiar with the details. Paul would be the person to ask
about that.
