I have configured the file "/etc/default/grub" on "Dom0" with the

GRUB_CMDLINE_XEN="dom0_mem=16G,max:16G dom0_max_vcpus=8"
Assuming your machine has this amount of memory, I may suggest this
troubleshooting actions...
update-grub
After this command, check /boot/grub/grub.conf (or menu.list, if Grub v1
is used). Make sure Xen's entry has the desired parameter. Otherwise,
it's your update-grub script fault.
reboot -h 0
While rebooting, inspect Xen's command line in the boot loader (press
'E' over Grub's menu entry). Make sure the desired parameter is there.
Otherwise, your boot loader is using a wrong config file (or you have
updated a wrong one).
But when the "Dom0" returns, I have only just "3465592" of total memory.
Once booted, check with xentop or "xm list" or "xl list" (depends on
what toolstack you are using). Inspect, how much memory did Xen assigned
to Domain-0 aka Dom0.
Note, that if your Dom0 is a 32 bits system, it won't be able to see
more RAM unless some workaround is activated, like using x86_64 kernel
or activating PAE.
