Log in to the Windows 10 guest VM, run Task Manager or Resource Monitor, and make sure that the Windows sees all allocated virtual cores.Ī physical processor of the host, Intel(R) Xeon(R) Silver 4114 CPU, is now displayed instead of a virtual one in the system properties. Save the configuration file and start the virtual machine. cores='4' the processor has 4 cores per socket.sockets='1' indicates that there is one vCPU (socket).host-passthrough is the emulation mode in which the virtual machine sees the physical processor of the cluster node.# virsh shutdown w10testvm – where w10testvm is the name of your virtual machine Let’s try to change the allocation of virtual cores for the KVM virtual machine. To use all CPU resources allocated to a virtual machine, it must see one 8 core processor, 2 vCPUs with 4 cores each or 1 vCPU with 4 cores in two threads instead of 8 vCPUs. In my KVM virtual machine running Windows 10, all assigned virtual cores are considered as separate processors.
Let’s see on how to assign virtual processors as cores in different hypervisors and how to bind it to the NUMA architecture used in modern processors. It means that instead of 8 vCPUs, you can add 2 vCPUs (2 sockets) with 4 per socket. Most hypervisors can provide vCPUs as processors, processor cores or even threads. In order to improve the performance of your virtual machine, you can use a processor with more cores. However, this restriction is not related to the number of cores. The problem is that desktop Windows versions (Windows 10/8.1/7) have a restriction on the maximum number of physical processors (sockets) a computer can use: Number of Processors Supported in Windows At the same time, a virtual server running Windows Server 2016 on the same hypervisor can see all 16 vCPUs allocated to it. It means that Windows 10 is able to use only 2 cores no matter how many of them you will add.
