Hi Nir & Francesco, with my qemu modifications in place I wrote a before_vm_start hook. It will remove memory hotplug from libvirt XML if VM is defined with machine type pc-1.0. #!/usr/bin/python import os import sys import hooking import traceback domxml = hooking.read_domxml() os = domxml.getElementsByTagName('os')[0] tp = os.getElementsByTagName('type')[0] mc = tp.getAttribute('machine') if mc == 'pc-1.0': m = domxml.getElementsByTagName('maxMemory')[0] d.removeChild(m) hooking.write_domxml(domxml) With this I'm able to start a Fedora cluster 3.5 based Windows VM on a Centos 3.6 cluster. And most important: It is still ACTIVATED. Just filed a RH BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1310458 Markus
