		<description>@Mike: I&#039;ve had problems like that before when I forget to clear UDEV before bundling. Read the parts above about clearing UDEV:

&lt;cite&gt;
NOTE: Each time you rebundle, you’ll need to re-issue the following command or udev will keep it’s IP address and the new image will not get a new IP via DHCP at first boot:
&lt;/cite&gt;

&lt;code&gt;
# prevent udev from keeping its old ip-adress
rm /etc/udev/rules.d/z25_persistent-net.rules
&lt;/code&gt;</description>

		<description>Dear Friends,

I have installed local machine for slackware13.1 and I have created new 
image for 10GB using below command and 

# dd if=/dev/zero of= bs=1M count=10000
# mke2fs -F -j 

and installed the custom package for slackware13.1

I have referred the below links and follow-up the steps, for pdf document. 

http://aws.typepad.com/aws/2010/07/u...mazon-ec2.html

I am using the kernel is linux-2.6-xenU.x86.tar.bz2. And I have download the kernel below liks
http://stacklet.com/downloads/kernels/xen/xenU-2.6.31

I have untar the xenU-2.6.31 kernel, I am getting 2 folders (/lib/modules &amp; /boot)
and installed the path like (/lib/modules folder in /lib path and boot file is stored in /boot path.

Also I have set the fstab entry for, and changed the above links steps also.

/dev/xvda1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0

And I have created the /boot/grub/menu.lst file and store the file 

default 0
timeout 3
title vmlinuz-2.6.31.6
root (hd0)
kernel /boot/vmlinuz-2.6.31.6 console=hvc0 root=/dev/xvda1 ro

and bundle with amazon aki (aki-407d9529) and upload the amazon server
and register it,

While run the instance, I am unable to login the server, I am getting
below error.

ec2-get-console-output i-ajht0c9

		<description>hi,

this link has been a real eye opener to people trying with a higher kernel version than the amazon provided default 2.6.16-33; especially if any of the OEM softwares being installed required a higher kernel version.

This worked for me for re-bundling my RHEL 5 update 3 AMI. 

But also I have few doubts to clear to get forward from the small hickup I face...that is, when upgraded to kernel 2.6.18 with the relevant AKI and ARI for x86_64 v1.0 (aki-9800e5f1 and ari-64b95e0d), and later updating with the kernel module ec2-modules-2.6.18-xenU-ec2-v1.0-x86_64.tgz, the AMI runs...but cannot be re-bundled successfully without specifying the AKI and ARI each time. If not specified, it do takes the newer AKI / ARI, but doesn&#039;t start the instance; instead gets terminated with Server.InternalError.

Is there anything I am missing in my steps?? I didnt do any udev installation though. Is this required on RHEL system? If so, how to do the same in RHEL distribution?

Also when extracting the kernel module, it also creates a boot folder. Do we need to copy its content to /boot folder just like we do for the lib/modules ??

Kindly help...your comments highly appreciated!!

thank you

		<description>I&#039;ve also been having these crashes. Pretty annoying.

Didn&#039;t know that the 2.6.16 kernels weren&#039;t suitable for large instances. Weren&#039;t these the default kernels a while ago?
BTW: Where did you find this information?

On to upgrading the kernels ...

Tnx for the info!</description>
