[libvirt-users] Difference between "Max Memory" and "Used Memory"

Hello, I am new on this mailing list, so If I do something wrong, don't hesitate to tell me :-) I am using the following version of libvirt : Compiled against library: libvir 0.8.8 Using library: libvir 0.8.8 Using API: QEMU 0.8.8 Running hypervisor: QEMU 0.14.0 I would like to understand the difference between "Max Memory" and "Used Memory" returned by a "virsh dominfo" command. In my configuration both values are equal. This surprises me because my VM is not using all its memory. Perhaps I miss something ? Thank you very much for your help. Regards, Jérôme
