vRO : Set latency level on VM

[kristofasaert]

Hello,

I'm trying to set the latency level on a VM with vRO.
I'm able to fetch the current status => System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);

However I've already tried several things to set the sensitivity but I always get error messages.
Currently I'm here:

System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);

var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = "high" ;

And this is the error I get:

Error in (Workflow:Change Latency Sensitivity / Scriptable task (item4)#35) Cannot convert high to com.vmware.vim.binding.vim.LatencySensitivity$SensitivityLevel

I'm not familiar with that setting, but it sounds like it's expecting an object or enumeration, and I found one in the API Explorer.  So maybe somethin like this?

var configSpec = new VcVirtualMachineConfigSpec();
var latencySensitivity = new VcLatencySensitivitySensitivityLevel(); 
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = latencySensitivity.high;

Hey emacintosh,

When I enter that I get this error:

ok, maybe it's just an enumeration and not an object.  This one didn't yell at me at all....

var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = VcLatencySensitivitySensitivityLevel.high;

[kristofasaert]

Indeed, it doesn't complain but now it didn't change the setting

My code:

System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);
var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = VcLatencySensitivitySensitivityLevel.high;
System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);

My log:

[2021-06-29 20:53:48.207] [I] sens level: DynamicWrapper (Instance) : [VcLatencySensitivitySensitivityLevel]-[class com.vmware.vim.binding.vim.LatencySensitivity$SensitivityLevel] -- VALUE : normal
[2021-06-29 20:53:48.209] [I] sens level: DynamicWrapper (Instance) : [VcLatencySensitivitySensitivityLevel]-[class com.vmware.vim.binding.vim.LatencySensitivity$SensitivityLevel] -- VALUE : normal

[kristofasaert]

It doesn't complain either but the setting isn't changed...

My code:

System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);
var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = VcLatencySensitivitySensitivityLevel.high;
System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);

My logs:

[2021-06-29 20:53:48.207] [I] sens level: DynamicWrapper (Instance) : [VcLatencySensitivitySensitivityLevel]-[class com.vmware.vim.binding.vim.LatencySensitivity$SensitivityLevel] -- VALUE : normal

[kristofasaert]

Indeed no error message but the setting isn't changed.

My code:

System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);
var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = VcLatencySensitivitySensitivityLevel.high;
System.log( "sens level: "+ vCenterVm.config.latencySensitivity.level);

Kristof,

Did you try with this PS?

[kristofasaert]

Hey Jose 😁,

I don't have a powershell host so I prefer to solve it in vRO natively.

But I've already found the powershell scripts for that function.

var task = vCenterVm.reconfigVM_Task(configSpec);
System.getModule("com.vmware.library.vc.basic").vim3WaitTaskEnd(task, true , 1);

[kristofasaert]

Ok so the post of Xian & emacintosh together cracked the case 🤑
Below code gives you the complete solution

var configSpec = new VcVirtualMachineConfigSpec();
configSpec.LatencySensitivity = new VcLatencySensitivity();
configSpec.LatencySensitivity.level = VcLatencySensitivitySensitivityLevel.high;
var task = vCenterVm.reconfigVM_Task(configSpec);
System.getModule("com.vmware.library.vc.basic").vim3WaitTaskEnd(task, true , 1);
