#1 Updated by Laurent Grawet about 8 years ago

Hi,

Sorry, I've hit the return key too quickly...
There should be a way to adjust CPU ratio on running instances to manage CPU overcommitment.

Best regards,

Laurent

You can do it in 4.0 if the instance is not running (poweroff, undeployed, pending...) Is this for VMs in RUNNING state or is this:

enough?

#3 Updated by Laurent Grawet about 8 years ago

I would like to to adjust the CPU parameter (not VCPU) for VMs in running state. According the new documentation, the VM can't be active.

As the CPU parameter is just for accounting purpose, it could be changed while the VM is running. This is the kind of parameter we would like to adjust while observing real CPU usage on the VM.

Hi,

Is it possible to add this feature to 4.6 roadmap ?

Thanks,

Beta is going to be released today, there are still some glitches with sunstone. The core changes are more or less straightforward (quotas need to be checked), but we need to propagate the feature upwards. These changes cannot be made for 4.6 Final. Very sorry for the inconvenience. Moved to high priority.
