Yes i have but as i wrote it a few lines below, my non-pae xen kernel
do a "kernel panic" when using it.
So, again, what can i do?
- Upgrade to Xen 3.1?
- Compile FreeBSD kernel with Pae enabled? (i'm searching for it but
haven't found one yet, is it a working option for FreeBSD?)
- Any other way?...

Hello everybody,
I'm having troubles creating a FreeBSD DomU.
I suppose that you use PAE-enabled kernel in the domain 0.
As for the present it is impossible to run
PV FreeBSD domain on a PAE host.
Here are the logs from Xen :

Is there an other builder option for Bsd systems?
I saw many post about people having the same problem but some told them to
use diffÃrent kernel for install or using different way like non pae
kernel.
As my Xen kernel do a "kernel panic" with non pae (Quad Core with 4Gb) i
can't try FreeBSD on my system.
What do you suggest to me?
- Upgrade to Xen 3.1?
- Compile FreeBSD kernel with Pae enabled? (i'm searching for it but
haven't found one yet, is it a working option for FreeBSD?)
- Any other way?...
Thanks in advance.
Julien.
