Re: [Xen-users] RedHat Enterprise Linux RPM - PAE question

[Edward Muller <edwardam@xxxxxxxxxxxx>]

FYI

Here is what I am doing:

I am using the Xen RPMS (from http://xensource.com/download/ 
dl_304rhel4.html) EXCEPT for the kernel RPM, on a RHEL 4 system.
I need to build some additional outside modules for use with the  
kernel that is going to be run on this system and they won't build  
without the source for a configured kernel. So I downloaded the Xen  
source tarball (from http://xensource.com/download/ 
dl_304tarballs.html) and did a 'make install-kernels'. This gave me a  
kernel, which I setup with grub and stuff. But when I reboot into  
that kernel I get the PAE MODE MISMATCH error.
I WANT to use all the xen rpms except for the kernel one ...

So the xen RPMS above were compiled with or without PAE?

I attached the relevant portion of my kernel config to the original  
post. I'm not 100% sure if PAE is enabled in the kernel for that  
matter or not.
