Task 10
An administrator is working to create a VM using Nutanix V3 API calls with the following specifications.
* VM specifications:

* vCPUs: 2
* Memory: BGb
* Disk Size: 50Gb
* Cluster: Cluster A
* Network: default- net
The API call is falling, indicating an issue with the payload:
The body is saved in Desktop/ Files/API_Create_VM,text
Correct any issues in the text file that would prevent from creating the VM. Also ensure the VM will be created as speeded and make sure it is saved for re-use using that filename.
Deploy the vm through the API
Note: Do not power on the VM.

Task 3
An administrator needs to assess performance gains provided by AHV Turbo at the guest level. To perform the test the administrator created a Windows 10 VM named Turbo with the following configuration.
1 vCPU
8 GB RAM
SATA Controller
40 GB vDisk
The stress test application is multi-threaded capable, but the performance is not as expected with AHV Turbo enabled. Configure the VM to better leverage AHV Turbo.
Note: Do not power on the VM. Configure or prepare the VM for configuration as best you can without powering it on.
正解：
To configure the VM to better leverage AHV Turbo, you can follow these steps:
Log in to Prism Element of cluster A using the credentials provided.
Go to VM > Table and select the VM named Turbo.
Click on Update and go to Hardware tab.
Increase the number of vCPUs to match the number of multiqueues that you want to enable. For example, if you want to enable 8 multiqueues, set the vCPUs to 8. This will improve the performance of multi-threaded workloads by allowing them to use multiple processors.
Change the SCSI Controller type from SATA to VirtIO. This will enable the use of VirtIO drivers, which are required for AHV Turbo.
Click Save to apply the changes.
Power off the VM if it is running and mount the Nutanix VirtIO ISO image as a CD-ROM device. You can download the ISO image fromNutanix Portal.
Power on the VM and install the latest Nutanix VirtIO drivers for Windows 10. You can follow the instructions fromNutanix Support Portal.
After installing the drivers, power off the VM and unmount the Nutanix VirtIO ISO image.
Power on the VM and log in to Windows 10.
Open a command prompt as administrator and run the following command to enable multiqueue for the VirtIO NIC:
ethtool -L eth0 combined 8
Replaceeth0with the name of your network interface and8with the number of multiqueues that you want to enable. You can useipconfig /allto find out your network interface name.
Restart the VM for the changes to take effect.
You have now configured the VM to better leverage AHV Turbo. You can run your stress test application again and observe the performance gains.
