RE: [Xen-users] RE: [Fedora-xen] Difficulties using the Fedora Core 4
by Petersson, Mats
Whilst I'm sure that Redhat is working on a publicly available RPM (or
similar) that you can install straight off, I would suggest that you
build your own Xen/Dom0 kernel. It's not TERRIBLY hard - although
there's some quirks and catches. This works for me:
Download some version of Xen from www.xensource.com (snapshot or 3.0.0
release).
Unpack into xen-<ver>
cd xen-<ver>
make world
<wait for some time>
cd *0 <this takes you to the Dom0 core>
make ARCH=xen menuconfig
<I personally turn off modules and enable devfs + smp, but you may want
other configurations>
cd ..
make install
cd dist
./install.sh
<edit grub.conf or similar to have lines like this:
title Xen-32
root (hd0,0)
kernel (hd0,0)/boot/xen-3.0-devel.gz dom0_mem=200000
com1=115200,8n1 console=vga,com1 sync_console
module (hd0,0)/boot/vmlinuz-2.6.12-xen0 root=/dev/hda1
console=ttyS0
>
If you use modules, you'll need to add a line saying "module
(hd0,0)/boot/initrd-xxxx", and you need to create the initial ramdisk
with "mkinitrd" in your linux-*0 directory. It's not hard, but to me
it's easier to just build a kernel with all the drivers in one file -
you loose a chunk of memory from this, of course. My kernel is a bit
over 4MB uncompressed code and a good megabyte of data on top of that.
Of course, your hard-disk layout may be different - adjust accordingly.
I hope this helps.

I think 1447 is no longer available for download. At least I can't find it
anymore. I could email you a copy if you can handle a 15 MB file. I'm not
promising it will work for you, just that it worked for me! I'm on an Intel
system, BTW.

Many people have had problems with those versions you mention. The Fedora
Xen packages were (and still are?) broken for a long time.
I've had luck on FC4 with kernel-xen0-2.6.12-1.1447_FC4, which I also use
for my domU.
Others using FC4 have had luck with Riel's fixes to the Xen Fedora packages:
http://people.redhat.com/riel/xen_for_fc4/
You might also check out the FC5 rawhide to see if their built-in Xen stuff
works yet.

I am bringing update my Fedora 4 for the FC5 to test the Xen of it, but it
would like to continue in the FC4.

Difficulties using the Fedora Core 4
by Leonardo Pinto
Hi, I am having difficulties using the Fedora Core 4 Updated.
I tried following kernels:
kernel-xen0-2.6.11-1.1369_FC4.i686: Dont initialize;
kernel-xen0-2.6.12-1.1454_FC4.i686: Initiates all good. However I receive
WATCHDOG... in the net card and after a time the system it breaks;
kernel-xen0-2.6.13-1.1532_FC4.i686: Kernel small alloc panic...
kernel-xen-hypervisor-2.6.14-1.21_FC5.i686: Executable not recognized...;
- Which version more would be indicated to use in the Fedora Core 4 Updated
for a AMD Athlon(TM) XP 2000+, 512MB RAM?

Xen 3 and kernel 2.6.14
by Gawain Lynch
Hi,
Since the release of Xen 3 I believe than support for 2.6.14 has gone
into -unstable. Are we likely to see this soon in rawhide as the
current kernels (and indeed anything older than 2.6.13) won't boot for
me on my test system.
I have not a lot on between now and the new year and am keen to test is
all :-)

Libvir: a simple C virtualization control library
by Daniel Veillard
This mail is to present a new project being started:
Libvir: a simple C virtualization control library
The libvir library is born from the need for a simpler userland C library to watch and control Xen domains. Among the design goal are:
- being able to provide API and ABI guarantee
- LGPL to be able to use it in a variety of contexts
- pure C, minimizing dependancies
- aiming at full documentation coverage
A typical example of use case should be the applet displaying local Xen
domains status in Fedora Core desktop.
The current state is a small library to get informations and interract
with existing domains, the design is not frozen, though the existing code
should work as is, it is considered mostly as a way to bootstrap and seed
the project, we are seeking interest from others. The library could be
extended in various ways potentally supporting other virtualization
mechanisms like QEmu, allowing to start new domains, etc. as long as the
API is kept simple enough.
The project is hosted at :
http://libvir.org/
API http://libvir.org/html/libvir-libvir.html
See the download page at http://libvir.org/downloads.html to get sources
or CVS checkout, and https://www.redhat.com/mailman/listinfo/libvir-list
for the mailing-list informations, which would be the best place to discuss
this for those interested in this project,
yours,
Daniel

Xen3 stability, x86_64 status?
by Paul Wouters
Hi,
A while ago I tried the xen3 kernels and userland, and found Rik van Riels packages the
most stable. Though still these continiously gave xend errors. I ended up using my own
compiled xen2 for production xen's.
Does anyone run xen3's based on rpm builds?
Does it run on fedora x86_64 yet?
