Re: [Xen-users] xen 3.0.4 - 22, 'Invalid argument' when starting domain.

[xensource@xxxxxxxxxx]

Thanks for this answer.

However it didn't helped me. I feel a bit lost now. I really don't know what 
to do...
I don't know how to set or not PAE and how to check if it's enabled, but to be 
sure I rebuild a domU kernel with the same sources as dom0. And I got exactly 
the same error. Only my dom0 boots correctly, not my domUs.

Here are additionnal informations :

When restarting xend, I have these strange lines in my /var/log/messages 
logfile, however this does not prevent xend to work correctly. (At least for 
the xm list command)
