Hi,

I'm a little bit new a Nutanix, however since last summer I can handle it very well

Now I got a question wich I want to share here.

I have to prepare a windows server.
The requirments of the software wich will be hosted on this server preverene dedicated CPU and memory.

So is this in the nutanix (AHV) installation posible to create a VM with his own dedicated CPU's (6cores) and memory?

 

Regards Peter

Hi @Peter_1966 

Do you want to pin a specific VM to a physical cpu on a AHV Host?

you can use acropolis cli (acli) vm.update namespace to enable vcpu to pcpu hard-pinning.

acli vm.update <vm-name> vcpu_hard_pin=<True or False> 

in AHV when you assign RAM / Memory to a vm, it is committed at power-on of the VM.

Hi Peter,

If we pin the CPU , after enabling can we increase the CPU or so does it allows to increase and how about the migration between the host . How its work in the backend .
Means if we enable the pin does the VM sticks to the certain regions of CPU or how it is working.
