Hi all, Today I found that dom0_mem option does not work in my 64G 2 cpu server , but works in my 16G 1 CPU server. I am using debian wheezy and xen 4.3.3. Firstly I set GRUB_CMDLINE_XEN="dom0_mem=6G,max:6G" in /etc/default/grub, Then execute: update-grub After rebooting, execute: xm list 0 Only see no more than 3967M reserved for Domain-0 in my 64G 2CPU server, however, my 16G 1CPU server display correctly. If I use xm mem-set 0 5000, dom0 memory also can be raised. But why it does not work with dom0_mem option?
