Subject: [ovirt-users] CPU Threads Help!!!
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 ???
Like Artyom mentioned, it best to see your lscpu output but my guess is
that the 4 threads is actually 2 per core.
And there are 2 core and 2 sockets. this means 4 cpus without hyper
threading and 8 with.
BTW the Host "General" subtab on the webadmin should output all this
info as well. Check it out.
Regards,
Jian
