Just a suggestion - is the boot order sequence for the server being provisioned set to PXE before internal disk? If so the newly built server will reboot, and before it gets to the newly built OS it will perform another PXE install.

What is your "server: " setting? It appears it's "cobbler", which will work as long as that resolves in DNS, otherwise you need to set it to a DNS resolvable name or IP.

James,

I did restart cobblerd...

And this is literally what I see now when issuing:

cobbler system getks --name=centos-workstation

Result:

wget "http://cobbler/cblr/svc/op/ks/system/centos-workstation" -O /root/cobbler.ks

Did you restart cobblerd after making the settings change? You should also be seeing this in the output from the kickstart_done snippet:


That is the trigger to disable the netboot flag.

James,

OK I ensured:

/etc/cobbler/settings:

pxe_just_once: 1

-and-

My kickstart ends with:

$SNIPPET('kickstart_done')

%end

I'm seeing exactly the same behavior...  In fact I just koan'd a new instance and its now on it's second install all by itself...

I am absolutely at a loss...  This all worked for me using stock CentOS 5.x hosts...  Really the difference is I'm using Xen as supported under CentOS 6.4 - so not sure if that has anything to do with this or not...

Yes, it should be the last thing before the %end, as you have it.

Have you also set pxe_just_once:1 in your cobbler settings?

James,

Curious - is something from the kickstart_done that does the right thing as far as ensuring "kick start" that KOAN initially uses isn't copied over or something like that?  To be honest, that's what it feels like is happening ... once installed the VM doesn't have the ability to boot off the installed bootloader and then simply uses the same "kickstart" to reinstall again...

I don't know if this may be the issue but at the end of my kickstart, it looks liek the following:

$SNIPPET('kickstart_done')

%end

Is that out of order maybe?

Thanks!

James,

Interesting!

So I have an old kickstart I've been using since Cobbler 1.6x days...  In it I have $kickstart_done - but when executing

cobbler system getks --name=centos-workstation

I see it is not expanded!

So I added the snippet to the end of my kickstart like so:

$SNIPPET('kickstart_done')

And now see:

wget "http://cobbler/cblr/svc/op/ks/system/centos-workstation" -O /root/cobbler.ks
wget "http://cobbler/cblr/svc/op/trig/mode/post/system/centos-workstation" -O /dev/null

However, I am still getting the reinstall happening...

Do you also have the kickstart done ($SNIPPET('kickstart_done')) snippet included in your %post section? That is the piece which notifies the cobbler server the PXE is complete and toggles the netboot-enabled flag.

Bryan,

Thanks for the response!

Alas this isn't a netboot problem - although at first glance I thought you were correct.  Unfortunately, I'm watching my VM reinstall itself again :(

It's almost like I "koan --replace-self" but that's not what I told it to do.  In fact, this is what I executed:

koan --server=cobbler --system=centos-workstation --virt

I literally see the VM install itself, bootloader installs then the VM shutdown and is started up again and its as if I initiated the original "koan --server=cobbler --system=centos-workstation --virt"

it is because of the "Netboot Enabled" flag in cobbler.

After the node begins its kickstart either change netboot enabled to false (unchecked) in GUI or run the following command:

cobbler system edit --name=<hostname> --netboot-enabled=0

That should fix it for you.

Make sure you do it AFTER it begins PXE (so during DHCP stage is fine, right after it gets its IP).

All,

I'm somewhat confounded by what I'm seeing when using KOAN.  I have a machine running CentOS 6.4 and installed CentOS-Xen using para virtualization (my hardware on this box doesn't support full virtualization)...

I had an old VM I created under CentOS 5.9 Xen which I migrated over to this new machine and it runs fine...

However, I am trying to spin up a new VM and what I see happening is the install proceeds as expected (again using KOAN).  I see in VNC when the boot loader installs and then the VM attempts to reboot and run...  What it does next is not expected:  the install proceeds again...and this continues forever...  Once it reinstalls, it reboots and reinstalls again...

This all works fine under CentOS 5.x - so it could be Xen 4.2 or it could just be me :)  Which, BTW, CentOS-Xen is 4.2 I believe.

Thanks ahead of time...
