Here are the details: Server =3D 4096MB RAM XEN 3.4.2 + kernel 2.6.18: xm info | grep total_memory =3D 4084 XEN 4.0.0 + kernel 2.6.18: xm info | grep total_memory =3D 3946 The exact same kernel config file was used for both builds. I also made=20 sure there is absolutely no difference on the hosts (while the builds=20 are created on a different machine). This seems like a regression, unless someone can provide suggestions on=20 how to correct this? Thanks. --=20 Alexander Williams IT Architecture Specialist Sp=E9cialiste de l'Architecture TI http://www.iWeb.com/
