I am creating a CentOS DomU on Debian lenny.
I am following this guide.
http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU
I created two volume groups.
One for swap another for root.
I downloaded kernels and initrd from here
http://mirror.centos.org/centos/5/os/x86_64/images/xen/vmlinuz
http://mirror.centos.org/centos/5/os/x86_64/images/xen/initrd.img
I did not wanted to create a kickstart file.
Here is centos5.cfg file I created.
-------------------------------------------------------------------------------------------------------------------------------
kernel = "/boot/vmlinuz-xen-install"
ramdisk = "/boot/initrd-xen-install"
#extra = "text ks=http://localhost/minimal-ks-x86_64.cfg"
extra = "text"
name = "centos5"
memory = "1024"
root = ''/dev/xvda ro''
disk = [
''phy:/dev/virtualization/centos5-swap,xvda1,w'',
''phy:/dev/virtualization/centos5-disk,xvda2,w'',
]
vif = [ ''bridge=eth2'', ]
vnc=1
vnclisten="0.0.0.0"
vncpasswd=''boguspasswd''
vcpus=1
on_poweroff=''destroy''
on_reboot = ''destroy''
on_crash = ''destroy''
-------------------------------------------------------------------------------------------------------------------------------
Is this .cfg file wrong.
Any help would be appreciated.
I am getting some error as Hotplug script not working.
How should I proceed ?
Some one suggested me to use vnc.I am not running Gnome Display on
Dom0 is it still possible
install by using vnc?

When following a tutorial, best stick with it all the way, changing something only after you''re sure what it does. Note how the tutorial maps the disk as xvda, instead of xvda1? They do that for a reason. While there are ways to map dom0 LVs as domU partition, that''s not the way to do it.

It could be anything from a broken installation, udevd dead, wrong bridge name, and so on. I''d start by making sure you have a working system first, and that you can create a working domU (any kind will do). After that, /var/log/messages, /var/log/daemon.log, and /var/log/xen/xend.log usually give some more info as to what went wrong. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

That is, you''d get one disk (xvda) with partition table on it. If you want to have a domU that doesn''t use partition on domU side (i.e. directly maps the disk as xvda1), you can''t use Centos installer. Some manual process is necessary. Your problem of "hotplug not working", however, should be unrelated to mapping xvda vs xvda1. I''d start by comparing the config files. Perhaps the bridge is incorrect? -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I am mentioning all the steps that I have done till now. Step 1) I created lvcreate --name domu3-swap --size 2G virtualization lvcreate --name domu3-root --size 98G virtualization Step 2) wget http://mirror.centos.org/centos/5/os/i386/images/xen/vmlinuz -O /boot/vmlinuz-xen-install wget http://mirror.centos.org/centos/5/os/i386/images/xen/initrd.img -O /boot/initrd-xen-install Step3 ) Created a centos.cfg file. Where gave path to above downloaded vmlinuz and initrd. Probably this file may have some error. You can see the file here This is a working domu cfg file http://pastebin.com/Kzvghk9e This is the file created based on above http://pastebin.com/5ZXqk6xp Step 4) Under section Example kickstart file on http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU I created a kickstart file.(Which later on after I found was not working had discarded the idea of using it and going to a text based install) Step 5) As far as my understanding is for VNC in /etc/xen/xend-config.sxp (vnc-listen ''127.0.0.1'') (vncpasswd ''a'') These two lines are to be there.If there is any thing more then let me know. Step 6) Also in DomU that is CentOS we are trying to install vnc=1 vnclisten="0.0.0.0" vncpasswd=''a'' Step 7) To start installation did xm create /etc/xen/centos.cfg -c After some minutes there was an error Hotplug scripts not working. Which ever step above was wrong let me know.If I have missed some thing then correct me. -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Look at several last lines (about 100 lines or so) on /var/log/xen/xend.log what does it say about centos5-disk and centos5-swap? Does it say device not found or something like that? Try shutting down your running debian domU, and change centos domU''s disk section line from disk = [ ''phy:/dev/virtualization/centos5-disk,xvda,w'', ''phy:/dev/virtualization/centos5-swap,xvdb,w'', ] to simply disk = [''phy:/dev/virtualization/research-disk,xvda,w''] That is, use a block device from your other domU that''s known to work. If it DOES work, don''t follow through with the install process though. Destroy the domU immediately with "xm destroy". This is simply to isolate whether the problem is in that particular block device or not. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I just changed the installation method of CentOS by using a utility called rinse .To my wonder it started xen-create-image --hostname centos5_domU --ip 192.168.1.50 --install-method rinse --force --dist centos-5 --arch=amd64 when I tried to boot xm create -c /etc/xen/centos5_domU.cfg showed me an error message missing destination file operand after `initrd-xen-install.img'' I had downloaded the files from here http://mirror.centos.org/centos/5/os/i386/images/xen/initrd.img I finally renamed to the initrd to initrd-xen-install.img then did xm create -c centos5_domu5.cfg I am able to see a CentOS welcome screen an image of which I have uploaded here I am not able to understand how now to select the installation things like English et I have done in past text based installations.Selecting space it had not selected the English on screen. The snapshot you can see here. http://www.flickr.com/photos/48996087@N07/4617619327/ and here http://www.flickr.com/photos/48996087@N07/4617619329/ I have no clue as how to proceed and post installation. Please see now it the discussion had been fruitful till here. On Tue, May 18, 2010 at 12:07 PM, Fajar A.

I tried by hosting CentOS on Dom0 and dom0 had a webserver but doing
installation it gaves following error
Unable to retrieve |
| http://http://172.21.100.147/ |
| /centos/images/stage2.img.
Where as I checked that file is there on the webserver.
I have uploaded a snapshot.

If they are not clear let me know where to upload if any one
interested to see them.

In /etc/xen/xen-tools I have used kernel and initrd the ones downloaded from CentOS site http://mirrors.kernel.org/centos/5.5/os/x86_64/images is it correct or wrong. In /etc/xen-tools/xen-tools.conf vmlinuz and initrd should point to the downloaded vmlinuz and initrd or the Debian Dom0 vmlinuz and initrd. ---------- Forwarded message ---------- From: Tapas Mishra <mightydreams@gmail.com> Date: Tue, May 18, 2010 at 1:19 PM Subject: Re: [Xen-users] cent os domu creation problem To: "Fajar A.

I am installing CentOs 5.5 as DomU on Debian Lenny running amd64 2.6.26-2-xen-amd64 I downloaded two files vmlinuz and initrd from here http://mirrors.kernel.org/centos/5.5...64/images/xen/ copied them to /boot and changed their names to vmlinuz-xen-install and initrd-xen-install In my /etc/xen-tools/xen-tools.conf I made following changes to be able to install centOS domu via rinse method Code: install-method = rinse dist = centos-5 kernel = /boot/vmlinuz-xen-install initrd = /boot/initrd-xen-install I mounted a CentOS5.5. ISO dd if=/dev/cdrom of=/root/centos.iso bs=1024 count=1 mount -t iso9660 -o loop /root/centos.iso /root/inscd/ So /root/inscd/ had the contents of CentOS cd Then I did to create image Code: xen-create-image --hostname=new_centOS --size=96GB --swap=2048 Mb --ip=192.1.100.19 --memory=1024 --arch=amd64 --role=udev --force --install-method=rinse --install-source=/root/inscd/ every thing went fine at the end there was a new_centOS.cfg file Then executed xm create new_centOS.cfg -c the output is following and it hanged in between no more proceeding.
