Hi, I installed the Xen 2.0 successfully,but I met following problems when booting up Xen: Boot-NFS: No NFS Server available, giving up NFS: Unable to mount root fs via NFS, trying floppy Can anyone help on this? Thanks very much! -Ning
> Hi, > > I installed the Xen 2.0 successfully,but I met following problems when > booting up Xen: > Boot-NFS: No NFS Server available, giving up > NFS: Unable to mount root fs via NFS, trying floppyThis is booting domain 0, rather than starting other domains, right? It probably means that the default kernel doesn''t contain a device driver for your disk controller. Is it some unusual scsi or sata controller? Try enabling it in the xen0 kernel config and rebuilding. If you look in the full boot messages you should see if any hardware is being discovered.

Ian, Thanks for reply. I use a dell 650 workstation, I guess Xen did not find a driver for my scsi controller. Your suggestions is too simple. How can fix it ?

Check your grub config file. You xen entry should look something like this:
title Xen 2.0 / XenLinux 2.6.9
root (hd0,2)
kernel /boot/xen.gz root=/dev/hdc3 dom0_mem=512000 console=vga
module /boot/vmlinuz-2.6.9-xen0 ro root=/dev/hdc3 console=tty0
module /boot/initrd-2.6.9-xen0.img

I met a problem when booting xen in dom0, the out is like this: md:.. autorun Done. Root-NFS: No NFS server available, giving up. VFS: Unable to mount root fs via NFS, trying floppy. VFS: Insert root floop and press ENTER. my grub is like this: title xen 2.0 / Xenlinux 2.6.9 kernel /boot/xen.gz dom0_men=131072 module /boot/vmlinuz-2.6.9-xen0 root=/dev/sda4 ro console=tty0 My machine is Dell workstation 650, scsi controller is LSI Logic 53C1030, my linux is redhat AS 3.0 Is there anything wrong with my grub?

Looks like your scsi driver isn''t compiled into the kernel. Not sure what driver you need for a 53C1030, maybe CONFIG_SCSI_SYM53C8XX_2 You''ll have to pull the source tar ball and follow the instructions for configuring your kernel.

When I use redhat AS 3.0 the scsi driver for 53c1030 is mptscsih when I build 2.6.9 kernel for my dell 650 machine, MPTbase module can not be found in the kernel, MPTbase module will be used by mptscsih. It is same when I build xen/xenlinux 2.6.9. thanks, -Ning -----Original Message----- From: xen-devel-admin@lists.sourceforge.net [mailto:xen-devel-admin@lists.sourceforge.net] On Behalf Of Ian Pratt Sent: Wednesday, January 12, 2005 5:15 PM To: Sun, Ning; Derek Glidden; Xen List Subject: RE: [Xen-devel] ask help on booting xen Looks like your scsi driver isn''t compiled into the kernel.

Hi I configed my system by following the suggestions. When I boot xen0, the following error msg printed on the screen: kernel panic-not syncing:VFS:Unable to mount on unknown block(8,4).
