Hyper-v failover, eth0 is now missing

[dreniarb]

Had a hyper-v host die on me. I did a failover on another host and EFA is running but there is no eth0, just lo. I removed the network adapter and added a legacy network adapter but it has not made a difference.

The other VMs that I had to failover came up just fine, but they're Windows machines. I'm not quite sure what to do at this point to with EFA though.

Any suggestions?

Delete /etc/udev/rules.d/70-persistent-net an reboot your machine.
Edit ifcfg-eth0 using a plain text editor and update the MAC address to reflect the new MAC-Address.
To avoid this for furture, set your MAC static in Hyper-V VM-Config.

This is a problem that can happen with other hypervisors, and the solution is the same.
