I installed Xen 3.1.0 from the sources and I compiled the xen0 kernel

make linux-2.6-xen0-build
make linux-2.6-xen0-install
depmod 2.6.18-xen0

When I boot the server choosing the "2.6.18-xen0" kernel I get this error:

Root-VFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy and press ENTER

And the server doesn't boot. If I boot with the "2.6.18-xen" kernel
created with the "make world" and "make install" commands I have no

What's the problem?

The kernel doesn't find the root file system.
Is your root file system on NFS?
Do you specify it on the kernel's command line?

Generally I'd start by comparing the kernel command line parameters in grub's menu.lst

Also - the mentioning of "update-grub" makes me suspect that this is a Debian system, if so then I'd recommend using kernel-package to build a "proper" debian package for the kernel.
