Re: [Fedora-xen] xen 3.4.1 + myoung x86_64 kernel



Thanks Boris, I finally have xen running!

I started over with a fresh F11 install and used JF git kernel with
xen-3.1.4-3.src.rpm. The system starts up just fine with or without xen
enabled on this 2.6.31-rc6 kernel.

The GDM/Xorg does not work though. I have an nvidia NVS290 in this
machine and the nouveau driver complained about not being able to load
the kernel module - directly followed by a backtrace dump in the Xorg
log. I then disabled the nouveau driver trying to get it done with vesa
driver - seemed to give no errors but ended up in the same kind of
backtrace.

on vesa:

Backtrace:
0: /usr/bin/Xorg(xorg_backtrace+0x26) [0x4e89b6]

any hints on how to get X back up again?

Thanks,
Mark
