Using costs in OpenNebula


I’m getting very confused… Sometimes, when I apply a cost value for “Disk”, it disappears and, then, when I calculate VM cost, I get an incorrect value.

I’m assigning theses values:

  • Memory: 0.0015 per GB (and hour)

  • CPU: 0.01 per CPU (and hour)

  • Disk: 0.000768 per GB (and hour)

However, as you can see at attached files, total VM cost is the same…

Is it a bug or am I doing anything wrong?


Hi Daniel,

This looks like a bug indeed. Could you open a ticket in For 6.0 we may end up unifying the TOTAL values for the VM, but at the very least we’ll correct this.
