Oracle VM DOM0

Dom0 is the initial domain started by the Xen hypervisor on boot. Dom0 is an abbrevation of

"Domain 0" (sometimes written as "domain zero" or the "host domain"). Dom0 is a privileged

domain that starts first and manages the DomU unprivileged domains.

Oracle VM calculation

dom0_mem = 502 + int(physical_mem * 0.0205)

To change the Dom0 memory allocation, edit the /boot/grub/grub.conf file on the Oracle

VM Server and change the dom0_mem parameter, for example, to change the memory

allocation to 1024 MB, edit the file to be:

kernel /xen.gz console=com1,vga com1=38400,8n1 dom0_mem=1024M
