Settings=System=Processor The box is already checked but the CPU doesn't have PAE capability so it's useless. It won't be a bad thing thatthe install may do a choice of a cpu with or not the capability of PAE as it was in the past. Red Hat decided that this newer version of RHEL(CentOS) *must* have PAE support by CPU to be installed. I think they would even prefer to loose i386 branch all together. Indication was when they supported (or just forced, cant remember witch) Virtualization only on x86_64 on RHEL/CentOS 5.x.

Indication was when they supported (or just forced, cant remember witch) Virtualization only on x86_64 on RHEL/CentOS 5.x. They only support KVM as a host technology for virtualization now. KVM requires the CPU virtualization extensions to function. The functions are only available on the CPU when in 64bit (long) mode. There are sound technical reasons for this and it wasn't just them being stubborn to drop an architecture. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
