Hi, Guys<= /p> Recently I am investigating the Optimization Policy in Cluster and try to use =E2=80=9CCPU Threads=E2=80=9D.=

As the manual of description:

=3D=3D=3D=3D=3D=3D=3D=3D

= For example, a 24-core

= system with 2 threads per core (48

= threads total) can run virtual machines with

up to 48 cores each=

=3D=3D=3D=3D=3D=3D=3D=3D

=C2=A0

My host CPU is

i3-2120 CPU=C2=A0 (2 cores 4 threads)

=C2=A0

So I think the expect result case is :

1. If the =E2=80=9C<= span style=3D"font-family:"Arial Unicode MS","sans-serif";color:black;background:white" lang=3D"EN-US">Count Threads As Cores= =E2=80=9D disable, we can=E2=80=99t run virtual vm with above 2 vCPU<= o:p>

2. If the =E2=80=9C<= span style=3D"font-family:"Arial Unicode MS","sans-serif";color:black;background:white" lang=3D"EN-US">Count Threads As Cores= =E2=80=9D enable, we can=E2=80=99t run virtual vm with above 4 vCPU<= o:p>

=C2=A0

Now the problem is about result case 1:

1. When I set =E2=80=9CCount Threads As Cores= =E2=80=9D disable, I still can run virtual vm with 4 vCPU<= /span>

=C2=A0

Can anyone help me to explain it ???

Regards,
Jian
