Re: Running FC4 on FC5

Dear Robert

First of all, I've had the same questions
and problems as you have now. This style of none documentation by the fedora
team is just a shame for the whole open source community! Probably Jeremy
Katz is too busy by meeting his new board members friends, so that he has
no more time to write just a little documentation with explanations, not
just a unusable mini mini howto.

What the big problem is behind the FC5
and Xen implementation is, that the xen guys at fedora have no idea what
SELinux is doing. So, finally they made an implementation of xen and SELinux
that is not usable. If you don't want to spend two weeks configuring your
SELinux, you have to decide, if you use in future SELinux or Xen (By the
way, the same issues you have with httpd and SELinux).

So my personal proposal is, that you
just disable SELinux wherever you find it on your FC5 installation. After
disabling SELinux (you have to reboot so that everything works fine, =>
Oh I like this old nice M$ Win95 style of system management) you can use
your xen config as you posted in your mail.

With the xenguest-install.py script
you can't install FC4 or another distribution, because the FC5 guys made
an adaptation of the anaconda system installer. By the way, this is a nice
feature, because you can now kickstart your FC5 installation.

If you want to install a new non FC5
guest, do it in the old style. Create your devices with LVM and perform
a yum groupinstall with --installdir=yourdevice.

As you can see, Fedora Core 5 is a typical
example for bad IT Management. They tried to do a lot of thing in a short
time. So several teams worked on different things and now, nothing really
fits together. The whole implementation of the SELinux is a disaster. So
for professional use, you have to go back to Fedora Core 4. Also because
the oracle stuff is not working with the new glibc (it's not possible to
start the listener... :-(). I by myself have to use FC5, because I need
to kickstart my xen installation and need apache 2.2. If you don't need
those features, use CentOS or the original RHES.

Hope I gave you the right hints.


bye Philipp

Subject	[Fedora-xen] Running FC4 on FC5

I am attempting to run an FC4 image on an FC5 machine
I have prepped the image as per the FC4 quick start
my xen config is as follows

kernel ="/boot/vmlinuz-2.6.13-1.1532_FC4xenU"
memory = 100
name = "vm01"
vcpus = 1
vif= ['mac=FE:FD:25:63:74:49']
disk = [ 'file:/root/VM/fedora.img,sda1,w' ]
root = "/dev/sda1"
extra = "ro selinux=0 3"

All I get is 

# xm create vm01
Using config file "vm01".
Error: Error creating domain: (22, 'Invalid argument')
Has anyone got a simple 1 NIC guest config for FC4 on FC5

I see that the new FC5 uses
An init image as part of the boot
A python based boot loader
and a python based install script

Is there any way to hack this lot to do an install like the FC5/FC5 one?
How are the init images built?
Will the new installer do other guest OS's in the future?

Robert
