I am very new to running vsphere on a server and was wondering how I can best allocate resources to my VMs. I am running light chess game simulations on each VM, and want 16VMs actively 24/7, with a dozen others switched on, but not running any processes. My main concern is that the CPU seems to be struggling at the moment. If I allocate a VM 1 socket and 1 core, the CPU hits 100% quite easily for that VM. If I allocate it 1 socket and 2 cores, it seems to do alright. Would I be able to run this many VMs with 2 cores each on my server ? It has 2x Intel® Xeon® E5620 (4x 2.4 GHz. with Hyper Threading).
See the attachment for the VM settings I will use on each VM, even though I might allocate 4gb memory to each, since I can easily upgrade to 128GB memory on my host server.
Really appreciate any help!
