 VM Customization is a new Azure VM feature that gives you greater control over the CPU resources of a virtual machine. It consists of two related capabilities:

 In the Azure portal, the VM creation workflow has a UI for these options.

 Once the VM is deployed, it has the specified number of vCPUs. If you set Threads per core to 1, the VM's OS sees half the usual number of processors (since hyperthreading is off). If you reduced vCPUs, it would see that lower count.

+To disable SMT and configure cores during instance launch:
 
 To disable SMT/HT, use the Azure CLI command and specify a value of 1 for vCPUsPerCore for the--cpu-options parameter. To configure cores, specify the number of CPU cores for vCPUsAvailable. In this example, to specify the default CPU core count for a Standard_D8s_v6 instance, specify a value of 8.

+```azure cli
 Az vm create --resource-group ccctest-rg-01 --name ccctestvm01 --image Ubuntu2204 --size Standard_D8s_v6 --location eastus2euap --admin-username azureuser --generate-ssh-keys --public-ip-address '""' --v-cpus-available 4 --v-cpus-per-core 1
 ```

 ## PowerShell
 
 To disable SMT and configure cores during instance launch
 
 Use PowerShell and specify the properties on the underlying configuration object. To disable SMT/HT, specify a value of 1 for vCPUsPerCore for the --cpu-options parameter. To configure cores, specify the number of CPU cores for vCPUsAvailable. 
-```
