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

This 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 ?

Thanks,
-Ning

What driver does the card need under native Linux?

You'll need to enable this in the xen0 kernel.

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

[Sun, Ning]

 
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? 
How can I fix this problem?

Thanks,
-Ning

Subject: [Xen-devel] -testing goes to 100%

Built and installed 2.0-testing from tarball as of today against 2.6.10 
patches for Dom0, and xend takes the CPU to 100% and leaves it there. 
Dropping back down to 2.0.2/2.6.9 makes it all appear business-as-usual 
so far.

Any "xm" commands go off into lala land without ever returning, but do 
respond to CTRL-C as one might expect and bring you back to the 
command-prompt.

Base system is gentoo. Athlon-XP.  My own kernel configs and not the 
ones built by xen, but the same config is used for 2.0.2/2.6.9 with no 
problems.  (I used "make oldconfig" to build the -testing binaries.)

Anything I can do to instrument this and see where the problem may lie?

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.

RE: ask help on booting xen

[Sun, Ning]

 
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

RE: ask help on booting xen

[Sun, Ning]

 
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).
How can I fix this problem?

Thanks,
Ning

I have the same problem as Ning has reported.  Please be gentle, as I'm a Linux
newbie ;-)  Re: David's advice below, this seems straightforward, and is what I
expected from Appendix B in the Xen user manual, but I do not have the
initrd-2.6.x-xen0.img file.  Presumably I can create it, but how?  Is anyone
prepared to hold my and through this?  Thanks in advance...

Quinton
