If I disable hyperthreading for a virtual machine on a dedicated host, does it apply to all virtual machines on the same dedicated host?

I would like to disable hyperthreading only for certain virtual machines connected to a dedicated host. As far as I know, I need to disable the hyperthreading feature applied to the virtual machine through the support request, but can I disable only certain virtual machines and enable the rest of the virtual machines?

    @유진

    My understanding is that hyperthreading is something that our Support team can disable per VM. Disabling it for a single VM should not affect other VMs on the same host even if using a dedicated host.

    Hope this helps! Let me know if you still have questions or need further assistance.
