hey there,
I wonder if someone could explain a question I have - i have a number
of Xen hosts with a similar configuration which all exhibit the same
behaviour:

'xm info' reports:
total_memory           : 86006
free_memory            : 2032

However, when using 'xm list', i see memory reported as:
Name  Mem
Domain-0 4025
HOST1 6144
HOST2 6144
HOST3 6144
HOST4 2048
HOST5 2048
HOST6 2048
HOST7 2048
HOST8 2048

I would expect that adding together the total guest VM memory, with
Dom0's and free_memory I should get something close to the
total_memory of 86006 reported rather than 34729.

Do i have something misconfigured or am I not understanding something correctly?

thanks in advance,
thorsten
