Sometimes being old is a double edged sword. For instance, RHEL7 has a lot of problems on AWS because the kernel is too old to properly support many of the virtualisation features AWS provides. On bare metal RHEL7 is great, though.

There are people working specifically on RHEL7 on AWS (and I am in the virtualization team, albeit working on the KVM side).

What features are you interested in?

Can you be more specific about this please?

Disclaimer, I happily work for RH and today's blog has me ear-to-ear grinning.

Hey sure, I should have been more specific. The enhanced networking in AWS requires ixgbevf at least version 2.14.2. In addition we had random hardlocks with ext4 under the centos7 kernel. Also we had a lot of difficulties running docker on EBS disks with the device manager driver - hard lock ups randomly. That's all I recall off the top of my head. All these issues disappeared upon moving to Ubuntu 16.04 on a later kernel. Centos7 was great for us otherwise, it just didn't seem to work out so well with Docker + AWS.

Here's another example: https://bugzilla.redhat.com/show_bug.cgi?id=1419877. live-restore works well on Ubuntu 16.04, afaict.

Red Hat is pretty good about back-porting features like this into the kernel and rest of the platform. It would surprise me if the issues you describe aren't on the roadmap to address.

We have no issues running RHEL7 under VMware.
