I asked to migrate existing CENTOS5-basedEC2 server to the new T2 instance. I created AMI, but it can't be launched as T2 instance because T2 supports only HVM virtualization. There are few manuals for converting AMI from PV to HVM (http://www.nixhat.com/2014/01/migrate-aws-pv-to-hvm-instance/, for example); but in order to do it, I need "to implant" HVM kernel into my server. But there is no CENTOS5 HVM AMIs! Is there any workaround?
May I use just vanilla CENTOS5 kernel - AFAIK, PV uses modified kernel, not sure about HVM?
