With the post-meltdown kernel (BOOT_IMAGE=/boot/vmlinuz-4.4.0-109-generic) labvirt1018 can't connect to its network:
```
* Starting set console font [ OK ]
* Stopping set console font [ OK ]
* Starting userspace bootsplash [ OK ]
* Starting Send an event to indicate plymouth is up [ OK ]
* Stopping userspace bootsplash [ OK ]
* Starting configure virtual network devices [ OK ]
* Stopping Send an event to indicate plymouth is up [ OK ]
Waiting for network configuration...
Waiting up to 60 more seconds for network configuration...
Booting system without full network configuration...
* Stopping Failsafe Boot Delay [ OK ]
* Starting System V initialisation compatibility
```
We've seen this before, which is why we pinned the lucky kernel version 4.4.0-81-generic. The networking issue occurred sometimes in kernels older and newer depending, although it seems like newer hardware in cases needed the extra package for drivers.

I think ` linux-image-4.4.0-109-generic` is right even though https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown?_ga=2.45330468.1075164870.1515518269-114292014.1505251686 notes `linux-lts-xenial 4.4.0-108.131~14.04.1 Trusty 14.04` because https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1741934/comments/17 was already filed and fixed bumping the correct version even though the docs are not updated?
