Have you ever been able to?  Dom0 is a virtual machine that only has 1 GiB.
Try xm info.

Subject: [Xen-users] Cannot see my memory - why?

Has anyone seen this issue below. 
Issue:
I cannot see most of my RAM from Domain-0 - even after a reboot

I have a CentOS 5.3 box with 16GB of ram and 8 CPU cores. I've set
Domain-0's memory to 1GB and my two DomUs to 4 GB and 2GB respectively (see
blelow).

#xm list
Name                       ID             Mem(MiB)     VCPUs    State     
Time(s)
Domain-0                  0                1024                8      
r------      2023.7
guest1                       1                4096                1      
r------      83.3
guest2                       3                2048                1      
r------      299.5

( ID #2 is missing because I destroyed it, removed it's config file and it's
disk - it's gone for good!)

When I check my system memory from Domain-0 using 'free -m' (the '- m' just
means show me in Megabytes), it shows that my box only has a total of 1 GB!
What the heck.   /proc/meminfo shows the same thing! Where did my ram go?

Any thoughts guys?


# free -m
             total       used       free     shared    buffers     cached
