I also saw this:
xentop - 18:04:44 Xen 3.1.0-53.1.13.el5
4 domains: 1 running, 1 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown
Mem: 2086396k total, 2076932k used, 9464k free CPUs: 2 @ 2666MHz
NAME STATE CPU(sec) CPU(%) MEM(k) MEM(%) MAXMEM(k)
MAXMEM(%) VCPUS NETS NETTX(k) NETRX(k) VBDS VBD_OO VBD_RD VBD_WR SSID
Domain-0 -----r 122 1.6 713728 34.2 no limit
n/a 2 4 4091 121100 0 0 0 0 0

12.6 1 1 1680 98659 0 0 0 0 0
xen top shows the full RAM, but the system itself doesn't?
