[Kimchi-devel] [RFC] - Guest Memory/CPU warning

Hi all, we have recently merged the patches that allow user to change guest memory and cpu. When user change this parameters, we have some problems: 1- If user assigned more virtual cpus than the amount in the host and start the VM, VM will start normally, but the host server will have the performance heavily declined. 2- If user assigned more virtual memory than the physical amount in the host, the VM does not start and qemu throws an exception like "Cannot allocate memory." Solutions: 1a - Show the number of host physical CPUs in edit Template and edit Guest windows, then warn the user if he assigns a higher number 1b - Show the number of host physical CPUs in edit Template and edit Guest windows, then does not allow to set up a higher number (generate a error during edition) 2a - Show the host MEMORY amount in edit Template and edit Guest windows, then warn the user if he assigns a higher number 2b - Show the host MEMORY amount in edit Template and edit Guest windows, then does not allow to set up a higher number (generate a error during edition) - A third option would be check the numbers before start a guest and warn the user, or does not allow the vm to be started. I would like to implement 1a and 2b. Do you have any thoughts or concerns/suggestions ? Rodrigo Trujillo
