Default Memory on dom0 xen host (etch)

Hi,

'memstat | sort -n' tell me at dom0 Xen machine:
71644k: PID 6538 (/usr/bin/python2.4)
1048576k: /proc/xen/privcmd 2600 6533 6540 17643
1491348k

1491348k is the total memory that memstat report.

'free' output is :
free
total used free shared buffers cached
Mem: 262144 241304 20840 0 12016 62220
-/+ buffers/cache: 167068 95076
Swap: 307192 692 306500


Is it telling me about to have 1.5 G of RAM on my dom0 ?

How do you interpret memstat output ?

Should all our machines have the same RAM size as stated by memstat
total memory output ?

How do you interpret the difference between free and memstat ?

Thanks you

Debian Rocks!

I now can read it is like a 'bug' on memstat

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=47260

I suppose memstat is counting /proc/xen/privcmd , and perhaps I should
use xm top and not free.
