Hi

 I ve installed xen 3.2.3 in DELL Server with Redhat Enterprise Server 5
Having Quad-Core AMD Opteron(tm) Processor 8350 & 32 GB RAM

While booting with PAE kernel  Memory shows 32 GB RAM

[root@careserver ~]# cat /proc/meminfo
MemTotal:     33264952 kB
MemFree:      28127132 kB

[root@careserver ~]# uname -r
2.6.18-8.el5PAE

While booting with xen kernel It shows only 13GB RAM in proc/meminfo
as well as the xm info

Here the xen rpms I ve installed

[root@careserver ~]# rpm -qa | grep xen
kernel-xen-2.6.18-128.2.1.el5
xen-devel-3.2.3-0xs
xen-libs-3.2.3-0xs
xen-3.2.3-0xs
xen-debuginfo-3.2.3-0xs

Will it show only the partial physical memory ?? .. Or any thing else
to be configured to get the total 32GB RAM with xen kernel??
How to get all the RAM with PAE support ??
Please give your valuable suggestions

Thanks in Advance
