Am I going to face any issues wanting to run some CentOS 5.x x86_64 boxes with 16 or 32 GB memory as Xen hosts with up to 10 or 12 GB memory CentOS 5.x x86_64 domUs ? Furthermore, am I going to encounter issues running CentOS 5.x i386 boxes with 8 GB memory trying to run CentOS 4.x i386 domUs with 3.5 or 4GB memory? Regards, Tom
