[chef] Re: Re: Re: Setting VM memory reservation with knife vsphere vm clone

Forgot to mention. I referred to the vSphere API docs for this. You can find them here:

Hi Terry,

Try the code given below to set the memory reservation. You will need the RbVmomi gem for this. It searches for a VM called 'test_vm' in a folder called 'vm_folder' and sets the memory reservation to 1024 MB.

#change_memory_reservation.rb

require 'rbvmomi'
vim = RbVmomi::VIM.connect host: '10.10.10.1', user: 'me', password: 'complex_password', insecure: true
vm = vim.serviceInstance.find_datacenter.find_vm("vm_folder/test_vm") or abort("VM not found")
vm_config_spec = RbVmomi::VIM.VirtualMachineConfigSpec
vm_config_spec.memoryAllocation = RbVmomi::VIM.ResourceAllocationInfo reservation: 1024
task = vm.ReconfigVM_Task spec: vm_config_spec
task.wait_for_completion

Regards,
Aditya

Hi Johnny,
Actually I set ram, CPUs, etc without creating a custom spec in vcenter, it works just fine without it. I was referring to memory reservation, not allocation.

But I'll take a look at the docs you pointed to and see if THAT allows me to set the reservation!

Thanks,
Terry

You use `--cram` option. `--cram 3` means 3GB RAM.

But yes before being able to specify RAM via `cram` (or CPU via `ccpu` for that matter), you do need to specify `--cspec`. To do that, in Vcenter, just create a customization specification (it's really basic info like timezone, dns, etc):

http://pubs.vmware.com/vsphere-55/index.jsp#com.vmware.vsphere.vm_admin.doc/GUID-58E346FF-83AE-42B8-BE58-253641D257BC.html

Then you can use `--cspec NAME` where NAME is the name of the customization specification you created.

Greetings all,

We are using knife vsphere to automate the birthing of over a hundred VMs, and it's working well.  One issue we can't figure out though is how to set the VM memory reservation during execution of the "knife vsphere vm clone" command.

I see there is the --cspec CUST_SPEC option, but I cannot find anything that explains what the format / syntax should be.  Can anyone please point me to where I can find that?

Thanks in advance,
Terry
