Xenner: How to manage domains with virsh?
by Felix Schwarz
Hi,
I got xenner to run on Fedora 9. And so far it seems that it is able to run at
least some of my paravirtualized guests which I created on Xen/Fedora 8.
Now the problem is how I can manage these domains using virsh? I can start a
Xenner domain using "xenner (and bunch of options)". Everything seems to be fine.
But "virsh list" does not show any active domains. So how can add the
configuration to virsh so that I can do something like "virsh start mydomain"?
Is this possible at all in the current Xenner (using Fedora 9 with all
released updates but nothing from updates-testing)?

Virtual Machine Manager
by gvm999
Hi all,
This is probably a stupid question, but I can't figure it out...
I want to try Virtual Machine Manager.
When I create a new machine, there is asked for a "Install Media url".
I want to install FreeBSD as a virtual machine, however, what url should I
specify then?
Or is this only for redhat systems? (fedora/centos?)
Greetings!

Assign IP and CONFIG_IP_PNP problem
by Alma Matex
Hi,
I'm new to Xen and I'm having problem with Xen networking.
I read that one could set the IP address of a new virtual machine in the
configuration file with the vif statement.
For example:
vif = [ 'mac=00:00:00:00:00:01, bridge=virbr0' ]
ip = "10.10.10.1"
My problem is that when the virtual machine start it doesn't get the IP.
Insted it uses dhcp to get one.
I found that the xen kernel must be compiled with the CONFIG_IP_PNP option
set, but my kernel doesn't seem to have it.
Infact:
grep CONFIG_IP_PNP /boot/config-2.6.21.7-3.fc8xen
gives me:
# CONFIG_IP_PNP is not set
Is this one the only problem?
Is there a way to get a fedora precompiled kernel with this option set?
Thanks
Regards

How to change hostname from cloned VMs
by Marcel Damásio
Hi all!
I have a question not specifically about virtualization.
I'm using virt-clone to clone my VMs.
But the new VMs generated have the same hostname as the original.
How can I change my VMs hostname without impact any application?
There are a lot of places that I can change the hostname, but I don't know
the right and garanteed way to do that change.

RE: Fedora-xen Digest, Vol 31, Issue 11
by Greg Cox
At which point do you receive the error message?
I ran into a similar problem where an xp guest would loose its mapping/path
to the install media or image after the initial reboot during the XP
installation.
After several months of banging my head against a wall, I finally found an
interface to set it manually in the machine details screen> Hardware Tab.
Setting the variable here will reconnect the device upon the next guest
boot.
A quick Google revealed this is a common issue but I was not able to find
the solution posted anywhere. When I have some time, I plan on posting it in
a few of the popular fedora forums.
Hopefully this helps, if not repost with a few more specifics and one of the
veterans may be able to steer you in the right direction.

xen network bridge with eth0:1 aliases, tmpbridge?
by Frank Liu
HI there,
I am having some troubles with xen network bridge on Fedora 8.
Searching bugzilla gives me
https://bugzilla.redhat.com/show_bug.cgi?id=193322 which seems to be
old.
This is a default fedora 8 installed with default xen installation. I
assume I should see a "xenbr0" interface, but instead, I see
"tmpbridge"
ifconfig -a

xend-debug.log says:
Error: either "local" is duplicate, or "secondary" is a garbage.
Does that mean xen in Fedora 8 still can't deal with eth0:1 alias?
In my case, I only want xen to use eth0 to bridge to the domU, and
eth0:1 is for some other apps on the dom0. I tried to put a
"netdev=eth0" in the xend-config.sxp and that didn't help.
Thanks!

Hi Aaron,
Thanks a lot for helping me. It worked.
I added into *'/var/lib/xend/domains/<UUID>**/config.sxp' *these
lines:
* (on_xend_start start)
(on_xend_stop shutdown)*
Now, the VMs are really auto starting and shutting down!
Thanks for helping me.

Are there any ideas that can use ISO file(ex: Fedora-8-i386-DVD.iso) to

Do you install vsftpd? If so, you mount ISO to /var/ftp/pub,
and vsftpd start, then you can install the local ftp server,
I think.

You can not install using the iso as such for a pv system. You will need
to install it through HTTP / NFS / FTP / ... ( I am normally using http,
& I am unsure if NFS is now supported ).
Install httpd server
yum -y install httpd
create a directory to mount your iso
mkdir /var/www/html/pub
mount -o loop /path-to-your-iso-image /var/www/html/pub
turn off SELinux & Firewall
setenforce 0
iptables -F
service httpd start
You should now be ready to install your Vm from
http://<ip of dom0>/pub
Hope this help.
Olivier
NB ; do not use localhost for the IP of dom0

Here there is a Fedora 8 Quick Start guide to create Xen guests:
http://fedoraproject.org/wiki/Docs/Fedora8VirtQuickStart#Building_a_Fedor...
I have installed guests using NFS and also FTP. If you already have
the ISO, you can do what Olivier mentioned to use HTTP or also mount
the ISO and share it through NFS.
See you,

vm create test ="losetup /dev/loop0 /data/xen/domains/test/disk.img failed"
by Christian Nitschmann
Dear mailing-list
after several attempts to start a xen linux-vm on a Fedora 8 XEN-System
(Quadcore Xeon-System with 8GB RAM and VT/PAE enabled), i now really
need your help.
I sucessfully created and installed a new debian etch-vm with the well
known debootstrap-script. I got 10 unused loop-devices which should
really be enough for at least one xen-machine.
When i try to start the new debian-etch-machine with "*xm create
/etc/xen/test -c*" i always get the error message:
-------------------------------
Using config file "./test".
Error: Device 2049 (vbd) could not be connected. losetup /dev/loop0
/data/xen/domains/test/disk.img failed

Autostart VM on boot
by Marcel Damásio
Hi,
I'm using Fedora 8 as DOM0.
I created my virtual machines using virt-install.
Now I want to configure them to autostart on DOM0's boot, but I can't.
I tried a lot of solutions, but none worked.
Could somebody help me?
