Visible memory..

Visible memory..

[Phil Carinhas]

  I have dom0_mem=1048576 in my xen0 boot line. That is all that 
shows up in top and /proc/meminfo. I have twice that much physical
memory. Shouldn't i allocate all of it? What am I missing. I have
big-mem support.

xm info (or the Node Info page on the Xensv interface) should tell you how 
much memory Xen is seeing / how much real memory is free.

Xen provides hard guarantees on the amount of memory a domain will get.  If 
you've got half of physical RAM for dom0, you can use the other half for 
other domains.

If you change your mind about your memory allocations, you can use the balloon 
driver (use xm balloon) to get domains to give back / take more memory.

HTH,
Mark
