Ubuntu 9.10 Server Grub2 does have issues with loading Xen Instance.
There are several well known workarounds.
1. Per PVops Wiki : adding dummy=dummy as first argument to kernel command line.
2. Build kernel with built-in command line.

Boris.

I tested the grub2 and it's loading Xen instance normally. Below my configuration file:

# cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 0ドル
# This file is an Xen custom entries
menuentry "Xen 3.4 / Debian Lenny 5.0 kernel 2.6.18.8-xen" {
insmod raid
set root=(md1)
search --fs-uuid --set e795a163-5418-4ae9-8021-83fe9ce05ea7
multiboot /xen-3.4.gz dom0_mem=512M iommu=1
module /vmlinuz-2.6.18.8-xen root=/dev/md3 ro console=tty0 pciback.hide=(06:0c.0)(06:0d.0)(06:0e.0)(06:0f.0)
module /initrd.img-2.6.18.8-xen
}

It was configured with xen 3.4.2 and without pvops kernel. I will try the xen 4.0.0rc6 and I will post the results.

Cheers

What's wrong with native Grub2 ( it doesn't load Xen Instance ?)

Guys!

For the first time, I have the Xen 4.0.0-rc6 with Linux 2.6.32.9 as my dom0 using the paravirt_ops.

The Intel modesetting is working too!

My xm info shows:

To install the "tools", I need to run:

make install-tools PYTHON_PREFIX_ARG=

And I'm using the Grub1.

Now it is time to make a few domUs!

Cheers!
Thiago
