Re: [Xen-users] Re: Running Xen 4.0.0-rc8 with Linux 2.6.32.10 paravirt_
apt-get build-dep xen-3.3 appears to be important to build tools with PCI pass-through
support. For boards without VT-D support it's unimportant. Just usual PV & HVM DomUs
I might miss something else.
So, to build xen&tools is safe to perform this build-dep on 10.04,9.10,9.04
I was wrong.
Boris.

Hi Thiago,
1. In case i would hard link /dev/xen/evtchn device with kernel ( in meantime 2.6.32.12)
This entry to /etc/modules would become unnecessary :-
echo "xen-evtchn" >> /etc/modules
2. I will check shortly , that
# apt-get build-dep xen-3.3 (causes more then 300 MB download)
is not required as well
I believe
apt-get install libcurl4-openssl-dev \
xserver-xorg-dev \
python2.6-dev \
mercurial gitk \
build-essential \
libncurses5-dev \
uuid-dev gawk \
gettext texinfo bcc \
bridge-utils iasl
would be enough to build Xen 4.0 hypervisor , tools and pvops kernel
Kernel might be built in Debian way as you suggested (apt-get install dpkg-dev debhelper) or not.
It should not be matter as well.
If i am wrong about build Xen 4.0 Dom0 with 2.6.32.12 kernel on top of Ubuntu 10.04 Server , please advise.
Thanks
Boris.

Hi!
This is a quick guide to help us to try the new Xen.
Also I have the composite window manager on top of the Xen! With full 3D support!
To achieve this I do:
1- Install your Ubuntu Desktop 10.4 beta1 and upgrade your system;
1.1 - Install some packages:
aptitude install build-essential libncurses5-dev dpkg-dev debhelper fakeroot
2- Download and install a new kernel with dom0 pv_ops enabled:
sudo -s
cd /usr/src
git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
cd linux-2.6-xen
git pull
git reset --hard
git checkout -b xen/stable origin/xen/stable
git pull
2.1 - Download the kernel config file attached to this mail (config-for-xen-2.6.32.10-pvops):
Copy the config file to the kernel source dir:
cp ~Downloads/config-for-xen-2.6.32.10-pvops /usr/src/linux-2.6-xen/.config
You can see the differences of my config file against the Lucid one:
diff /boot/config-2.6.32-17-generic ~Downloads/config-for-xen-2.6.32.10-pvops | vim -
...both are close to each other.
2.2 Configure, compile and install:
make menuconfig # Enable the dom0 support and the Xen backend/frontend/xenfs stuffs...
make
chmod g-s /usr/src -R # To avoid the error: "dpkg-deb: control directory has bad permissions 2755 (must be >=0755 and <=0775)"
make dep-pkg
dpkg -i ../linux-image*2.6.32.10*.deb
depmod 2.6.32.10
update-initramfs -c -k 2.6.32.10
update-grub
echo "xen-evtchn" >> /etc/modules
Now you can try your new kernel without Xen, if you want, it should work smootly.
3- Download and install the latest Xen:
Preparing your environment:
apt-get build-dep xen-3.3
aptitude install uuid-dev iasl texinfo
Download and compile:
cd /usr/src
hg clone -r 4.0.0-rc8 http://xenbits.xensource.com/xen-unstable.hg
cd xen-unstable.hg
make xen
make tools
make stubdom
make install-xen
make install-tools PYTHON_PREFIX_ARG=
make install-stubdom
update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20
4- Configuring your Grub2 through the file /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 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.10 pvops" {
insmod ext2
set root=(hd0,1)
multiboot (hd0,1)/xen-4.0.0-rc8.gz dummy=dummy
module (hd0,1)/vmlinuz-2.6.32.10 dummy=dummy root=/dev/mapper/HyperDeskVG01-tcmc--dell--lucid ro
module (hd0,1)/initrd.img-2.6.32.10
}
---- cut here ----
Don't forget to change your "root=" option of your Linux!
Run update-grub again:
update-grub
5- Reboot into your new dom0!
reboot
6- Look if your Xen is up and running
xm list
xm info
.. if not:
/etc/init.d/xendomains stop
/etc/init.d/xend stop
/etc/init.d/xend start
/etc/init.d/xendomains start
xm list
xm info
-
Cheers!
Thiago
