Description Rolf Fokkens 2006-12-03 07:24:09 EST

Description of problem:

Unable to run non-linux guests paravirtualized

Version-Release number of selected component (if applicable):

kernel-2.6.18-1.2849.fc6xen

How reproducible:

100%

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
  
Actual results:

Non Linux guest will probably never run virtualized

Expected results:

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.

Comment 3 Rolf Fokkens 2006-12-24 07:30:20 EST

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.
