Missing Enhanced Networking drivers on Ubuntu 14.04 HVM #109

Closed ltagliamonte closed 8 years ago

ltagliamonte commented 8 years ago

On 2.6 the Ubuntu 14.04 (ami-711ca91a) hvm is using the vif net driver:

root@localhost:~# ethtool -i eth0
driver: vif
version:

the 2.5 on Ubuntu 12.04 (ami-711ca91a) hvm is properly configured to use the Enhanced Networking drivers (even if not at the latest stable):

root@localhost:~# ethtool -i eth0
driver: ixgbevf
version: 2.7.12-k

More info about Enhanced Networking and how to enable it here

I do not know how and if i can help with a PR on this one because it needs also aws grants.

Thanks for your report. I suspect this is a duplicate of #61 so I'm going to close it and you can continue further discussion there.

Additionally, while I'd be willing to review a PR, this is unlikely to get attention from me in the short term. ComboAMI is primarily useful for PoC's and general tire-kicking, where enhanced networking isn't required. For production deployments where you need performance, ComboAMI doesn't help you with any of the ongoing management tasks you need to perform (all of which are as complex or more so than the initial deploy), and it's better to do your own install from scratch so you can control details like this.
