Windows Desktop 2 CPU max

Did anyone notice that somehow we lost the ability to have more than 2 cores.  Well, 2 cores and # of threads with a Windows 10 pro installation?  I can see the processors in the device manager, but task manager keeps saying 2 sockets, 2 VPUs.  I'm assuming I need to do something in the background, but sadly I'm a VMWare jockey in most places so still trying to learn.  Any suggestions?

I saw @ac9hp ran into a similar issue in his thread:

He adjusted the settings by tweaking the msconfig side of the house.  In my case, I need to adjust the configuration of the vim I think.

I had a similar thing happen (although I don't remember if I had created the antlet from a blank-kvm template or some other Win10 template).

I stopped the antlet, then edited the definition directly (from the antsle command line as root using virsh edit antletname).  In that file, you can find a section about CPUs and I was able to set it to 1 Socket, 1 Core, 8 threads (or whatever you need):

In my case, since I wanted 8 cores:

<vcpu placement='static'>8</vcpu>

Then further down a little, there's this section:

<cpu mode='custom' match='exact' check='partial'>

<topology sockets='1' cores='1' threads='8' />


Same issue here, I do not see the <topology sockets='1' cores='1' threads='8' />   did you add that?

I didn't add it, but I had to change the numbers.

Here are the first lines in my XML showing the vcpu and cpu sections

<domain type='kvm'>

<memory unit='KiB'>8388608</memory>
<currentMemory unit='KiB'>8388608</currentMemory>
<vcpu placement='static'>4</vcpu>

<type arch='x86_64' machine='pc-i440fx-2.4'>hvm</type>
<boot dev='hd'/>


<vmport state='off'/>

<cpu mode='custom' match='exact' check='partial'>

<model fallback='allow'>Westmere</model>
<topology sockets='1' cores='1' threads='4'/>

<clock offset='localtime'>

<timer name='rtc' tickpolicy='catchup'/>
<timer name='pit' tickpolicy='delay'/>
<timer name='hpet' present='no'/>


odd, i do not have that. Thank You for posting yours, i may try and add it and see what happens
