Hi QEMU dev Virt Manager is able to configure a QEMU VM with more CPU sockets than the physical host has. For example, in the below VM, when I request 16 vCPU cores, by default it takes as 16 Sockets with 1 core each. The host itself has only 2 Sockets.
1. How does QEMU allow this and how the VM works? 2. What is the recommended configuration of Sockets/Cores/Threads for best VM performance of a 16 core VM running on a 2 sockets host ?
