--------------020500020201060207010309 Content-Type: text/plain; charset="UTF-8"; format=flowed Content-Transfer-Encoding: 8bit Hi, Guys Recently I am investigating the Optimization Policy in Cluster and try to use “CPU Threads”. As the manual of description: ======== For example, a 24-core system with 2 threads per core (48 threads total) can run virtual machines with up to 48 cores each ======== My host CPU is i3-2120 CPU (2 cores 4 threads) So I think the expect result case is : 1. If the “Count Threads As Cores” *disable*, we can’t run virtual vm with above 2 vCPU 2. If the “Count Threads As Cores” *enable*, we can’t run virtual vm with above 4 vCPU Now the problem is about result case 1: 1. When I set “Count Threads As Cores” *disable*, I still can run virtual vm with 4 vCPU Can anyone help me to explain it ???
