= Allocate physical cores for virtual machines
:context: virt-physical-cores-allocation-vms

toc::[]

[role="_abstract"]
As a cluster administrator, you can allocate a full physical core to a specific virtual machine (VM), instead of allowing different VMs to share the same physical core.
Configuring your VMs to use only full physical cores can optimize performance for high-throughput or latency-critical VMs.

Allocating only full physical cores is important on simultaneous multi-threading (SMT) enabled systems because it offers the following benefits:

* Prevents noisy neighbors and resource contention
* Mitigates performance degradation
* Offers predictable latency
* Guarantees exclusive CPU resources
