Re: [one-users] Some questions about overcommitment in OpenNebula 4.2 using KVM
Hi, Do you know if the CPU parameter has any effect on the amount of real cpu used, e.g. if I set the CPU parameter to 0.1 will this limit the actual cpu usage?

Re: [one-users] Network addressing and IP recognition in ONE
Jaime, Thanks, Ill try to have some script that reads from one end and feeds the other end. However, do you foresee useful to have some kind of daemon inside the VM that will update the IP address shown in ONE? For instance, a VM is configured with a context that has the IP and port of a REST service on ONE. Once the ONE daemon inside the VM has started and it gets a valid IP address, it pushes that information to ONE, so the IP address shown in the WEBUI is valid. I assume there will be some other dependencies VMID, for instance but it could be a nice feature to deploy VMs in a mixing environment, or to have a centralized network server. It may not work with all network drivers, as it stills requires to have a virtual network assigned with VLAN tagging not having a virtual network or some tagging at layer 2 would mean defining manually the MAC-IP pairs.

Re: [one-users] How to exit SHUTDOWN_POWEROFF?
Hi This is probably because OpenNebula is waiting for a result of the shutdown operation. The driver has not answered back, and the VM is stuck in that state. About the fix, I am afraid that 3.8.3 requires modifying the DB and set the state manually. This has to be done in the XML document describing the VM. Since OpenNebula 4.0, oned offers you a onevm recover API call to fix these kind of issues.
