Re: [Kimchi-devel] [RFC] Guest/Template CPU setup with topology

Hi there, At this moment Kimchi support for guest and template CPU setup is underwhelming. Here's what I've found that needs improving: - edit template: * calculation of max CPUs is wrong when considering a topology. Max CPU is the value of sockets * cores * threads. At this moment it is considering only cores * threads, defaulting sockets to 1. * There is no way to set or even see the value of sockets. Given that this value is used in the calculation of the max CPUs, it should be at least visible and, in my opinion, editable

- edit guest (not running): * If the guest was created with a CPU topology, there is no way to edit it. The only way to edit a topology at this moment is on the template level. My proposal is: edit template: - fix the max CPU calculation to consider the sockets. - add a field to allow the 'sockets' to be set at will. Default value will be retrieved by the kimchi/host/cpuinfo API as a reference (same think as with cores and threads today). edit guest: - if the guest was created with a CPU topology, allow the topology to be edited when the guest is turned OFF. Thoughts?

ps: this RFC is also related to the feedback of "Bug fix #1072 - changing vpus verification​".
