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 at onefe1:~$ onehost show 11

Here is the result of running kvm.rb on the host:

oneadmin at hpblade1-1:~$ /var/tmp/one/im/kvm.d/kvm.rb
HYPERVISOR=kvm
TOTALCPU=2400
CPUSPEED=2933
TOTALMEMORY=49450776

FREECPU=2174.4
USEDCPU=225.6
NETRX=2052917131737
NETTX=2341806785454
FOO=bar

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