- Recently published Red Hat/CentOS kernel version - kernel-2.6.32-696.18.7.el6.x86_64 is failing to boot on a para virtual instance. This is a known issues which is under investigation with Redhat. Happen to CentOS 4, 6 etc. The workaround changing grub configuration to boot to previous kernel. grub.conf says "default=0" so it is booting the newest kernel on the first entry in the file. If I could easily override this from within the web interface for AWS EC2 and tell it to boot the next entry i.e. the equivalent of "default=1" or similar
- There's a problem with this workaround when using the old official centos images since they have a product code and as such when trying to mount it on another machine we get the following error:
"Error attaching volume: The instance configuration for this AWS Marketplace product is not supported. Please see the AWS Marketplace site for more information about supported instance types, regions, and operating systems." the fix I used was to build a specific editing instance using the exact same CentOS image that was used originally for the borked instance. https://aws.amazon.com/marketplace/library/
