[Kimchi-devel] [PATCH] Fix a ZeroDivisionError when starting kimchi service in Qemu.

When using kimchi inside a virtual machine it's possible to get a ZeroDivisionError exception because self.sockets is 0, so the division self.cores_per_socket = self.cores_present/self.sockets will fail. In this case, self.sockets is 0 because cores_present = 1 and threads_per_core = 4, which will truncate 0.25 to 0 during the integer division. This is a low priority corner case since kimchi is obviously not supposed to run under a virtual machine but for a plugin development, which will not use any virtualization capability, it might become handy.
