Adding Viktor, Andreas. Andreas, since we are the first ones going forward with cpu is a device (on a command level) we still have to provide the old cpu_add and query commands to make libvirt work regarding cpu hotplugging. Are you ok with having the x86 commands as wrappers around the new ones? Christian
