All of my production virtualization hosts here are now on Proxmox and are running the CentOS/Debian version mix guests in KVM. Still learning the tuning of Proxmox. > Can anyone speak to how well a virtual machine will perform when being > given 1 socket 1 core, vs. 1 socket 2 cores vs 2 sockets 1 core? I have not found any noticeable difference in whether a CPU is in a separate socket or just another core in one socket when using KVM virtualization. But I've also not done a deep-dive into benchmarking it, either, so I reserve the right to be wrong. This is with a mix of CentOS versions on a Proxmox host; all CentOS versions I've tried there have run well (and I have tried ALL major CentOS versions on Proxmox, including CentOS 2.1 through 5.....)
