This is without dom_mem boot parameter and with 64-bit Xen and dom0 Linux. Native Linux reports correct memory size. > > > > Huh. You are right.

I tried this last night and it seems that this problem has existed in 3.0 and in 3.1 as well. So not a regression but rather something we had never fixed. Interstingly enough you can experience the same problem with 8GB - you end up having 6GB in dom0. Naturally you can balloon up (hadn't tried to do it under 4GB with 2.68GB but it looks like you can certainly do it).
