Red Hat Bugzilla – Bug 218209
PAE too restrictive for Xen
Last modified: 2007-11-30 17:11:50 EST
Description of problem:
Unable to run non-linux guests paravirtualized
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Download Opensolaris or OpenBSD guest image
2. Do "xm create ..." and watch /var/log/xen/xend-debug.log
3. Be disappointed by the fact that you can only run paravirtualized Linux
Non Linux guest will probably never run virtualized
The full functionality of paravirtualization
And non-PAE won't support larger memory configurations. We're stuck between a
rock and a hard place here. PAE is the current choice and this will not change.
You can easily build a non-pae version from source if you wish.

Patch for kernel src.rpm to build a non-PAE kernel with xen.
The submitted patch helps to build a non-PAE kernel from source. As said: It's
easy, but it takes a while to do it right as building kernels takes a long time
on my system. So for convenience of the interrested... the patch.
