After tracing the execution of the IM host update I found the problem.
Alas, it was my fault.
/var/lib/one/remotes/im/run_probes runs all the scripts in
/var/lib/one/remotes/im/kvm.d/ (paths translated to /var/tmp/one/... on
the hosts).
We use cfengine to manage files so there was a kvm.rb.cfsaved in
/var/lib/one/remotes/im/kvm.d/. Its output would supersede the output of
kvm.rb.
Thanks,
Mark

Hi,
If you are seeing FOO=bar in the template that shows that the
informations flow is right, and one.db updated. Could it be that the
values generated by the modified kvm.rb change from execution to
execution?
Cheers

When you modified the scripts you must execute

I've run "onehost sync". There wasn't a change. Just to be sure
the script was being executed I added "FOO=bar" to the output.
Here is "onehost show"
oneadmin@onefe1:~$ onehost show 11

Could there be something preventing the one.db from being updated?
Could I flush it somehow?

I've modified /var/lib/one/remotes/im/kvm.d/kvm.rb to allow
overcommiting CPU and memory but I'm encountering some
inconsistencies.
When I run the script on the host I get:
TOTALMEMORY=247253880
However, onehost show gives
TOTALMEMORY="445056984"
How could the onehost be getting that value?
