Hi,
I tried doing that but it failed
#cat /etc/default/grub
  GRUB_TIMEOUT=5
  GRUB_DISTRIBUTOR="Fedora"
  GRUB_DEFAULT=saved
  GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=True rd.luks=0  KEYTABLE=es       
  LANG=en_US.UTF-8 rhgb"
  GRUB_CMDLINE_XEN= "dom0_mem=2G,max:2G"
  #GRUB_THEME="/boot/grub2/themes/system/theme.txt"
# grub2-mkconfig -o /boot/grub2/grub.cfg 
  /etc/default/grub: line 5: dom0_mem=2G,max:2G: command not found
