Hi everyone,

I just migrated four Ubuntu 14.04 LTS Linodes from Xen to KVM in the Atlanta data center. After the migration, I'm getting the following message spammed in the syslog on all four servers:

Aug 19 23:31:52 artemis kernel: init: hvc0 main process (27367) terminated with status 1
Aug 19 23:31:52 artemis kernel: init: hvc0 main process ended, respawning
Aug 19 23:32:02 artemis kernel: init: hvc0 main process (27369) terminated with status 1
Aug 19 23:32:02 artemis kernel: init: hvc0 main process ended, respawning
Aug 19 23:32:12 artemis kernel: init: hvc0 main process (27371) terminated with status 1
Aug 19 23:32:12 artemis kernel: init: hvc0 main process ended, respawning

It seems to happen every ten seconds or so. I'm assuming I have to disable some (or most) of my ttys so I'm trying to figure out how to do that in Upstart now. I was wondering if anyone else has had this issue...

UPDATE: Okay, hvc0 is for the Xen hypervisor, which is obviously no longer needed. Here's what I did to solve the above problem:

sudo stop hvc0
sudo rm /etc/init/hvc0.conf
sudo rm /etc/event.d/hvc0 # on hosts that were upgraded from 10.04 LTS

Why this wasn't done automatically during the migration, I can't say. Hope this helps someone in the future...

Thank you,

Mike
