Ok, we know that > 2G of dom0 is not currently supported with the way
we track memory today, described in:

I'm surprised we need as much as 256M just to load dom0, but happy
that 2G works now.
I'm surprised that any amount from 64M to 2G (currently forced in 16M
increments) does not allow for Dom0 to successfully make it thru init.
If fact, the maples (which only have 512M) give 192M to dom0 by
default.
These are OOM issues with the kernel?
If you cap Linux (without Xen) to these memory limits does Linux
succeed?
lets pick on 192, can you post a complete log?
