Summary: dom0 @32 bit can not "see" more than 16GB of ram Product: Xen Version: unstable Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P1 Component: Hypervisor AssignedTo: xen-...@lists.xensource.com ReportedBy: marc...@gmail.com CC: marc...@gmail.com

It seems impossible to let the 32 bit dom0 addressing more than 16GB of memory. My environment is a system with 26GB of ram, centos 5.0 32 bit, kernel-xen-2.6.18-53.1.14.el5.centos.plus. I've installed a upgaded xen and xen libs downloaded from the web site: xen-libs-3.2.0-0xs.centos5 and xen-3.2.0-0xs.centos5. Moreover I installed the last grub from the grub web site configured to accept the mem parameter at boot.

I've done many posts at the xen mailing list about this problem.
