[one-users] VMs in PENDING [was: Fixing up USED / FREECPU ?]

[Carlos Martín Sánchez]

Hi Steffen,

In your original scenario, you could replace the DB contents for your Host,
with OpenNebula stopped.
Since you have migrated your VMs, you can force the host deletion editing
the onehost command [1]:

Just change

        if host['HOST_SHARE/RUNNING_VMS'].to_i != 0
            puts "Host still has associated VMs, aborting delete."
        else
to

        if false
            puts "Host still has associated VMs, aborting delete."
        else



Maybe these kind of inconsistencies could be managed by the new onedb
command, we'll consider adding this feature for next releases.

Sorry for the late response; best regards,
Carlos.
