We have installed RHEL 5.2 Server ( i386 image ) on a machine with 64GB of
RAM.

When booting the default PAE kernel ( 2.6.18-92.el5PAE ) that is shipped
with RHEL 5.2 installation the OS detects 64GB of RAM.
But when booting the Xen kernel ( 2.6.18-92.el5xen ) the OS detects only
14GB of the total amount of available RAM.

Did anyone encounter this problem before ?


I did when I first installed RHEL5.1 on a server with 32GB of RAM.

Is it a normal behavior for a 32 bit image ?

Yes, 32-bit supports up to 16GB. To use the rest of the RAM, you'd needto install the 64-bit kernel-xen. Some docs are here:

Hope that helps.

Tom
