Hi Eduardo, thank you for your answer.
I am afraid that using free to show the ram allocated for the dom0 has
generated a bit of confusion.
I know how free works. The problem is that I disabled the balloon in
dom0 (but doesn't boot with a fixed ram) but in my examples i have:
free_memory> total_memory - dom0_memory

This does not match with:
"free_memory: available memory (in MB) not allocated to Xen, or any
other Domains"

I must set a fixed amount of ram for see correct values in free_memory?

Thanks,
Muriel
