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 Regards Rajiv,R, Project Associate, CARE,MIT, Anna University. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I think 32bit PAE Xen hypervisor is limited to 16 GB max memory support. You need 64bit Xen for 32GB RAM. dom0 kernel can still be 32bit PAE, if you need that.> 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 >where did you get these rpms?

[Xen-users] Re: [Xen-devel] Regarding PAE kernel with Xen 3.2.3
Thanks for your suggesstions Pasi I ll try out the link you ve given>> where did you get these rpms?RPMS i ve build it from the xen3.2.3 soure using rpmbuild Regards Rajiv.R Project Associate, CARE,MIT, Anna university On Wed, Jul 29, 2009 at 1:03 PM, Pasi Kärkkäinen<pasik@iki.fi> wrote:> On Tue, Jul 28, 2009 at 01:00:16PM +0000, Rajiv Rajaian wrote: >> 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 >> > > Is this 32bit kernel/xen?
