Little progress.

I took .config from Ubuntu 10.04 server headers and compiled jeremy
git kernel with it.
Obviously its almost full kernel config enabled.

I tried to boot xen with it - I can see the output - but it ends with panic.

Please see enclosed screenshot.

Grub entry looks like this:

menuentry "Xen 4.0.1-rc4-pre / Ubuntu 10.4 kernel 2.6.32.16 pvops" {
insmod ext2
set root='(hd0,1)'
multiboot (hd0,1)/xen-4.0.1-rc4-pre.gz dom0_mem=1024M dummy=dummy
com1=115200,8n1 console=com1,tty,vga com1=115200,8n1
module (hd0,1)/vmlinuz-2.6.32.16 dummy=dummy root=/dev/sda1 ro nopat
console=tty0 console=ttyS0,115200n8
}

But still cant get serial output, but at least I can see error on the
screen outpu.

Any idea?

Peter
