[Xen-users] how to get xen with a kernel 2.6.27 or above?
Hi list, I am starting a academic security related project and I was wondering if there is any documentation on compiling xen/dom0 with a recent kernel? I''ve seen a few good intentioned threads, but no real documentation so far. Any helpful pointers will be greatly appreciated! Thanks in advance, - SDG P.S: First mail, not sure if I should post it here...let me know if I am on the wrong list. :-) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] how to get xen with a kernel 2.6.27 or above?
Some one explained me in detail on community so I am forwarding same here
This guide will explicate in detail about the procedure for compiling
vanilla kernel from source and customize it according to your hardware
specifications and then compiling latest XEN from source and patching
it with Linux.
First install these packages:
sudo apt-get install iproute bridge-utils gcc make gettext
sudo apt-get install libcurl4-openssl-dev è openssl problem resolved
sudo apt-get install python-dev zlib1g-dev bcc libsdl-dev pciutils-dev
è zlib problem resolved.
First we will compile latest XEN Hypervisor from source.
Go to http://www.xen.org/products/xen_source.html and download the
latest XEN hypervisor from there. [Version 3.4.1 at the time of
writing the guide]
Xen 3.4.1 is available WITH and WITHOUT 2.6.18 dom0 kernel. We need
the version without dom0 linux because we will compile our own vanilla
kernel.
I am seting up XEN 3.4.1 on amd64 hardware and running debian
distribution on it with upgraded kernel.
My hardware specifications:
unme -a
Linux -04 2.6.31.4-user-kvm-vanilla #1 SMP Wed Oct 21 16:35:11 BST
2009 x86_64 GNU/Linux
Build / Install Xen
1. mkdir /home/tapas/xen
2. cd /home/tapas/xen
3. tar -xzf xen-3.4.1
4. cd xen-3.4.1
5. make xen
6. make install-xen
7. make tools
8. make install-tools
Build Vanilla kernel
Now we will build th PV_Ops Kernel. The Vanilla kernel source will be
downloaded from Jeremy''s tree. Jeremy''s git tree on kernel.org
contains the pv_ops dom0 patches. If we use Jeremy''s tree then we do
not any extra patches to bind XEN with kernel source.
1. mkdir /home/tapas/linux
2. cd /home/tapas/linux
3. git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
4. linux-2.6-xen
5. cd linux-2.6-xen
6. git checkout origin/xen/master -b xen/master
7. make menuconfig [see Note below]
8. make-kpkg clean
9. CONCURRENCY_LEVEL=N fakeroot make-kpkg --initrd
--append-to-version=-custom kernel_image kernel_headers
10. This will make the debian packages in the parent directory which
you can install
Note: Please choose the following xen specific optiions in kernel configuration.
Processor type and features ---> Subarchitecture Type (PC-compatible)
---> (X) Enable Xen compatible kernel
Bus options (PCI etc.) ---> [*] PCI support

Xen version compatibility (3.0.4
and later) --->
After xen confiuration, please make sure that .config has the
following parameter configuration:
* CONFIG_XEN=y
* CONFIG_XEN_MAX_DOMAIN_MEMORY=32
* CONFIG_XEN_SAVE_RESTORE=y
* CONFIG_XEN_DOM0=y
* CONFIG_XEN_PRIVILEGED_GUEST=y
* CONFIG_XEN_PCI=y
* CONFIG_PCI_XEN=y
* CONFIG_XEN_BLKDEV_FRONTEND=m
* CONFIG_NETXEN_NIC=m
* CONFIG_XEN_NETDEV_FRONTEND=m
* CONFIG_XEN_KBDDEV_FRONTEND=m
* CONFIG_HVC_XEN=y
* CONFIG_XEN_FBDEV_FRONTEND=m
* CONFIG_XEN_BALLOON=y
* CONFIG_XEN_SCRUB_PAGES=y
* CONFIG_XEN_DEV_EVTCHN=y
* CONFIG_XEN_BACKEND=y
* CONFIG_XEN_BLKDEV_BACKEND=y
* CONFIG_XEN_NETDEV_BACKEND=y
* CONFIG_XENFS=y
* CONFIG_XEN_NETDEV_BACKEND=y
* CONFIG_XENFS=y
* CONFIG_XEN_COMPAT_XENFS=y
* CONFIG_XEN_XENBUS_FRONTEND=m
Install these debian packages using
sudo dpkg -i <name>
Add the following line to /etc/fstab
none /proc/xen xenfs defaults 0 0
and reboot the machine.
After installing the debian packages, the Grub Entry will look like
the following:
title Xen 3.4.1 / Debian GNU/Linux, kernel 2.6.31.4-tapas-xen-4
root (hd0,0)
kernel /boot/xen-3.4.1.gz
module /boot/vmlinuz-2.6.31.4-tapas-xen-4 root=/dev/sda1 ro
console=tty0
module /boot/initrd.img-2.6.31.4-tapas-xen-4
Hope that will help.

What about Xen 4 I read about it some where isn''t it released ?

I am not yet aware if there is already an "unstable" tree that will possibly translate into 4.0 at some point in the future, but I also seem to understand that before we go into 4.0, a 4.3 stable release will exist, so I suppose 4.0 is scheduled to late January. - sdg _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Unfortunately, I haven''t had enough time to experiment any further (create VMs, configure them, etc). I noticed the xenU kernels weren''t built though.
