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.

No, even the bare Linux 2.6.32.9 (the same vmlinuz and ramdisk images used by Xen as dom0) doesn't boot by Grub2 (without Xen)... With Grub1 all works just fine... Maybe the problem is with me, I'm not familiar with Grub2...  hehehe... But I tryed it (Grub2) a lot without success...

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
