RAM Issue

[SBJ95]

I'm running OpenSuSE 11.0 RC1 with kernel 2.6.25.5-1.1, and top & System Monitor say I have ~512MB of Physical RAM. I have ~892 MB Physical RAM, and I can prove this by doing a 'dmesg | grep emory'. I'm running SuSE as a dom0 on Xen, but that shouldn't matter as all this is once SuSE is loaded. I have no idea what's going on. Any help would be greatly appreciated.

Well, it says that you only have 538624 kB total mem which is 1/2 a gig and that you have also used up some swap
MemFree: 8148 kB
It looks like it would like some more ram.
The last time I booted SUse it seemed to use lots more memory then anything else.
