[Bug 767218] Re: Guest machines crashed during apt-get update/upgrade on Lucid

[sysadmin-nawfi]

Serge,

We'd have to go back a ways to get the logs you need.  What kind of
"oopses" did you have in mind?

I think most of it is explained above, i.e.:

1) An update to some component of libvirt and/or kvm was part of an
update to the VM _host_.

2) Upon installing the update, the update process itself killed off the running kvm's (two of them).
I watched it happen before my eyes.

3) The kvm's you see listed _were_ after I restarted them manually.
They did not auto-restart after the update.

My whole point in arguing that this is a serious "bug" is that messing
with VM's is a whole new class of issue for updating server
environments.  It's one thing to have some update programs know how to
stop/restart some process (such as a relatively time-insensitive SMTP
server) but it's a whole 'nother thing when you take down a complete
VM!!!  The host simply cannot know what all the dependencies are on the
running VM.

Hence, this is _really_ important!

I'll include the term.log and dpkg.log files from the relevant time
window.  If there is something else you need, I can uplink it.
