[Xen-users] Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
Guys!
Tomorrow in my "live" presentation at Linuxcon Xen Directions!
I''ll show
the Xen Live CD to the public!
To celebrate! I want to share my last procedure to get and run Xen 4.0.1 on
Ubuntu 10.04 64 bits, here we go:
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
module (hd0,4)/boot/vmlinuz-2.6.32.18-tcmc-10.08-1-xen dummy=dummy
root=/dev/sda4 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...
Done!
Cheers!
Thiago

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
Hey Guys! Need some help here... I am trying to install Xen4.0.1 on Ubuntu 10.04.1 LTS (64 bits) which has the kernel version 2.6.32.24-generic. I followed this tutorial for the installation, using the configuration file uploaded by Thiogo, which is actually meant for kernel version 2.6.32.18. The kernel compilation steps go through smoothly, except that when I enable the xend and the xend domain services using the update-rc.d command I get the same warning message as NunziaG84 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 then when I reboot the machine, xend does not start. On issuing the command /etc/init.d/xend start, or status, there is no terminal output. When I type in "xend start" directly, I get the following error message: sudo xend start> > the output is: > > ERROR Internal error: Could not obtain handle on privileged commandinterface> (2 = No such file or directory) > Traceback (most recent call last): > File "/usr/sbin/xend", line 36, in <module> > from xen.xend.server import SrvDaemon > File"/usr/local/lib/python2.6/dist-packages/xen/xend/server/SrvDaemon.py",> line 26, in <module> > import relocate > File "/usr/local/lib/python2.6/dist-packages/xen/xend/server/relocate.py", > line 28, in <module> > from xen.xend import XendDomain > File "/usr/local/lib/python2.6/dist-packages/xen/xend/XendDomain.py", line > 36, in <module> > from xen.xend import XendOptions, XendCheckpoint, XendDomainInfo > File "/usr/local/lib/python2.6/dist-packages/xen/xend/XendCheckpoint.py", > line 20, in <module> > from xen.xend import balloon, sxp, image > File "/usr/local/lib/python2.6/dist-packages/xen/xend/image.py", line 46,in> <module> > xc = xen.lowlevel.xc.xc() > xen.lowlevel.xc.Error: (1, ''Internal error'', ''Could not obtain handle on > privileged command interface (2 = No such file or directory)'') >I see that several other people here are facing similar issues. Could anyone throw some light on what the matter might be, and how one could move towards resolving it. Does anyone have a configuration file for my specific xen and host operating system kernel versions. Actually I am confused as to whether the kernel version of the .config file has to match that of our Xen download or our host operating system.... Thanks!!!!

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
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!

If you wish, you can add the modules to your modules list in /etc/initramfs-tools/modules, then they will automatically be added to your initrd when you run update-initramfs to create your initrd.

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
I''m not completely sure, but while I was playing with Xen, I met this error. I happens when older xen-utils contact with newer hypervisor (or newer utils with older hypervizor??? not sure). Dirty solution: clear all signs of xen utils and xen themself from system (not only uninstall, not only aptitude purge, but manual removing any noties about xen from filesystem). (You can keep installation directory). After cleaning install required version, it shall works fine. В Чтв, 16/09/2010 в 08:11 -0400, Priya пишет:> Hey Guys! > > > > Need some help here...

If not, then you can try mounting it manually. If xenfs is compiled as a module, you may have to modprobe it first.

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).

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
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
module (hd0,4)/boot/vmlinuz-2.6.32.18-tcmc-10.08-1-xen dummy=dummy
root=/dev/sda4 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...
----------
Thanks!

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
Hey guys!
Thanks for the continued support and advice. It seems like my job is not
done yet.. :(
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............

Re: [Xen-users] Re: Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D
Yes, the direct edit should work and is a much easier approach. To add to my previous suggestion perhaps, for use in other circumstances; you can run update-grub from a chroot if you prepare /dev and /proc ahead of time. Assuming dom0 root was mounted on /mnt/a, doing a mount --bind /dev /mnt/a/dev && mount -t proc none /mnt/a/proc ahead of creating the chroot would suffice. On occasion I''ve also used kpartx and makedev to be able to install grub from a chroot on domU''s using file based images.

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
module (hd0,4)/boot/vmlinuz-2.6.32.18-tcmc-10.08-1-xen dummy=dummy
root=/dev/sda4 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...
----------
Thanks!

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.

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.

Probably udev could/should take care of this during boot, but i''ve just decided to configure my kernel with these devices as built-in. If you wish, you can add the modules to your modules list in /etc/initramfs-tools/modules, then they will automatically be added to your initrd when you run update-initramfs to create your initrd.
