There isn't any guest configuration in /etc/xen since F8 or F7. Memory for guest can be set in libvirt[1]

  • Dump XML config if 'virsh edit' is not available (i.e. on F8 libvirt-0.4.4)
virsh shutdown f11
virsh dumpxml f11 > f11.xml
  • Add currentMemory parameter which defines minimum memory given to guest at boot.
  • Enact this guest config in Xen via libvirt.
virsh define f11.xml
virsh start f11
  • See that free -m in guest now reports 519 total.

Actually, I think I may be confused about the meaning of currentMemory as I could balloon down from 519 and back up to it, but could not go above the value of currentMemory. [2]
