Hard to say. It could be tuned a lot more than it is (especially wrt to
the kernel config). With a standard Xen kernel I can balloon down to
12MB and things seem ok.
Ballooning down to 8MB leads to the OOM killer kicking in.
I reckon 16MB is probably a reasonable foot print to shoot for in the
future. My goal is to, at some point, build an LVM-aware ramdisk that's
under 4MB with a full Xen management toolset on it.
