[Fedora-xen] General question on running guests in FC5/Xen

[Srinivasan S]

Hi

First of all apologies for making all of you read this long email.  I 
have posted to multiple lists to get my setup running.  Inspite of 
enthusiastic help I have not got it running yet and hence this 
fundamental doubt.

I had a system running FC4 and Xen 2.x.  The same system had normal 
installations of Suse and Ubuntu.  I had a running setup wherin I 
started xen0 in FC4 and was able to run the installed Suse and Ubuntu 
as guests within FC4.  (This worked perfectly and I was able to 
connect to the guests using both RealVNC and FreeNX.)

I have now upgraded to FC and have been attempting to get the same 
setup running.  I first tried with the official Xen tarballs.  Not 
successful, I then tried yesterday with the FC5 xen kernels.  No 
success.  The problem in both cases is that Suse and Ubuntu guests 
load but virtual networking does not work.  Only lo interface is up.  
On the main FC5 xen0 domain, I am able to see vifx.x being added as 
and when a guest boots up, but the guest itself is without an 
interface.

Various searches on Google finally got me one hint on loading module 
xennet (for FC5) which I did in modprobe.conf.  Same result.

Search on web got me guides to load guests from images, starting 
guest installs from fedora, debian etc but could not find any info on 
running already installed linux distros within Xen.  The closet was 
in the xen manual which explains how to make an image of an installed 
linux distro and then running the image within xen.

Question:  Is what Iam trying to achieve possibly with Xen 3.x (since 
it worked with 2.x) ?  If yes can anyone help ?  My guest config file 
is a very simple one :

kernel = << Tried both the xen kernel and the FC5 xenU kernel >>
memory = 100
name = "suseguest"
vif= ['mac=aa:00:10:00:00:10, bridge=xenbr0, ip=192.168.2.2']
Also tried vif= ['']
gateway = "192.168.1.1"
netmask = "255.255.255.0"
disk = ['phy:hdc3,hdc3,w']
Also tried disk = ['file:/dev/hdc3,hdc3,w']
root = "/dev/hdc3 rw"

Please note that OpenSUSE is installed on /dev/hdc3

All help is appreciated in resolving this.

Thanks and Best Regards
Srini
