Checkout /etc/default/grub. I am pretty sure Lucid hides the grub
menu by default now. Not sure if you can hit a key to make it
appear so you may have to use the desktop cd and use a chroot to fix
things.

I finished
the installation using Thiago's documentation and the
configuration file from Boris.
While building the kernel, I kept the
default setting for all the questions that came up at the
prompt.
When I set up the xend and the xendaemon
services using, I still get the earlier warning:
update-rc.d
xend defaults 20 21
the output was:
update-rc.d: warning: xend start runlevel arguments
(2 3 4 5) do not match LSB
Default-Start values (3 4 5)
update-rc.d: warning: xend stop runlevel arguments
(0 1 6) do not match LSB
Default-Stop values (0 1 2 6)
And after rebooting the
machine, I don't even get the grub2 choices
for boot. All I get is a Kernel Panic message
saying:
kernel panic - not syncing
: VFS: unable to mount root FS on
unknown-block
Obviously, this is a
problem with the grub file that I
created, but shouldn't I at least get
the option to boot up the Ubuntu 10.04
that was initially working?
Now, can anyone please
tell me how to correctly assign "root"
to the correct hard disk partition
("hda.?") while creating your custom
grub file in the /etc/grub2.d/
directory?
Now that
I don't get the options from grub about which OS
operating system I want to boot up from, is there
a way to change the grub file to point to the
correct hd partition? State of complete collapse
at this time............

Hey Boris!
I am using your configuration file
to install xen4.0.1 from scratch.
Thanks! Could you please also send
me the grub entry (or the file that
you made for the xen boot in the
/etc/grub.d/ directory). I just want
to confirm that it is the same as
the original tutorial.
Also, did you change anything else
from the steps given below (from the
original mail by Thiago) while
installing your version:
-----
The procedure:
1- Install all the packages:
aptitude update
aptitude install bridge-utils
build-essential libncurses5-dev
dpkg-dev debhelper fakeroot uuid-dev
iasl texinfo git-core
apt-get build-dep xen-3.3
2- Download, compile and install
Xen and its tools:
cd /usr/src
wget http://bits.xensource.com/oss-xen/release/4.0.1/xen-4.0.1.tar.gz
tar xf xen-4.0.1.tar.gz
cd xen-4.0.1
make xen
make tools
make stubdom
make install-xen
# make install-tools
make install-tools
PYTHON_PREFIX_ARG=
make install-stubdom
3- Download, compile and install
Linux from the Jemery's tree:
make prep-kernels
wget http://livexen01.worldweb.com.br/linux-config-2.6.23.18-xen-4.0.1-1-tcmc-10.08-1
-O
build-linux-2.6-pvops_x86_64/.config
cd build-linux-2.6-pvops_x86_64
make menuconfig # Change whatever
you want, if you now what you're
doing...
make
chmod g-s /usr/src/ -R
make deb-pkg
dpkg -i
../linux-image-2.6.32.18-tcmc-10.08-1-xen_2.6.32.18-tcmc-10.08-1-xen-*.deb
depmod 2.6.32.18-tcmc-10.08-1-xen
update-initramfs -c -k
2.6.32.18-tcmc-10.08-1-xen
4- Enable Xen at boot:
update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21
20
5- Configure the Grub2:
vim /etc/grub.d/40_custom
---- cut here ----
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to
add custom menu entries. Simply type
the
# menu entries you want to add after
this comment. Be careful not to
change
# the ‘exec tail’ line above.
menuentry 'Xen 4.0.1, Ubuntu 10.4
kernel 2.6.32.18' {
recordfail
insmod ext2
set root='(hd0,4)'
multiboot
(hd0,4)/boot/xen-4.0.1.gz dummy=dummy
dom0_mem=832M

i915.modeset=0 earlyprintk=xen ro
module
(hd0,4)/boot/initrd.img-2.6.32.18-tcmc-10.08-1-xen
}
---- cut here ----
NOTE.: Pay attention to you root
partition and also you'll need to
disable the KMS (maybe the nomodeset
option works for you) of your
videoboard.
update-grub
reboot
Choose the right Grub2 menu entry...

There is no "/proc/xen" either!
What do you
all recommend?
Should I use a
different
kernel (if so
which one) or
a different
.config file?
Can I fix the
present set up
in some way?
I find it
amusing that I
am learning
stuff about
the internal
setup of Xen
that I
wouldn't have
had this
install been
"seamless"...
Cheers to
that!

That's a core
issue , why
xend fails to
start. During
pvops Dom0
load "udevd"
should
create :-
# ls -l
/dev/xen
total 0
crw-------
1 root root
10, 58 Sep 16
18:41 evtchn
crw------- 1
root root 10,
57 Sep 16
18:41 gntdev
On any system
Ubuntu 10.04.1
Server,
F13,F14,etc
Then xend will
start after
Dom0 gets
loaded.
Boris.

Do you
have xenfs
mounted?
see if the
following line
comes up in
the list if
you type
mount:
# mount
...
xenfs on
/proc/xen type
xenfs (rw)
...
If not, then
you can try
mounting it
manually. If
xenfs is
compiled as
a module, you
may have to
modprobe it
first. If it
is not enabled
in
your
kernel, then
you have to
rebuild your
dom0 kernel,
and enable it.
On my (Ubuntu
Server 10.04.1
based) system,
this gets
mounted
automatically
by either udev
or xend itself
(it is not in
fstab).
In my
experience on
this system,
xend fails
ususually due
to one of the
following
reasons:
1) Failure to
mount xenfs
(because it is
not
configured, or
the module
is
not loaded).
2)
Inconsistent
installation
of xentools
(in wrong
python
directory or
mixed with
older
version).
Regards,
Mark.
