I am booting up some Amazon EC2 instances. Specifically, Alestic instances in us-east for Ubuntu 10.04, 10.10 and 11.04. When I log into those machines I can use "
uname -a" to check the kernel versions. And as expected, they are different: 2.6.32, 2.6.35 and 2.6.38.
To my great surprise, however, their AKI is actually the same! That is shown in the web-based management portal, and also by the
When I look into the
/boot directory, I can see the kernel image files, such as
vmlinuz-2.6.38-8-virtual. The names are appropriate for what "
uname -a" shows on that instance and they are also of different sizes.
So, what is going on here? I was under the impression that you can use specific AKIs to get different kernels in your machines. Here I see different kernels, but the same AKI?
If you could help me to understand this, I would much appreciate it.
Thank you very much...
