Set the following parameters about the VM template:

Name, Image, Hypervisor, Resource cluster, and Description

Step 4 Click Next.

The VM Template Specifications page is displayed.

Step 5

Set the following parameters about the VM:

OS type, OS version, Number of CPUs, Memory, Number of disks, Capacity, Thin provisioning,Affected by Snapshot, HA, and Clock sync

Thin provisioning: If thin provisioning is enabled, the physical disk space is shared and storagespace is dynamically allocated only when data is written into the disk. Thin provisioning allowsmore virtual memory space to be allocated than the real memory available, because most of usersdo not use all the memory space allocated to them. You are advised to disable thin provisioning fordisks that run performance-intensive programs.

This mode cannot be enabled for disks that do not support thin provisioning. Check the availabilityof thin provisioning in the following way:

a. Choose Resource > Resource Pool.

The Resource Pool page is displayed.

b.

Choose Data Center > Data Center > Zone > Computing Resource Pool > Resource cluster.


c. On the Storage page, check whether there are storage devices that support thin provisioning.

- If yes, enable or disable thin provisioning.

- If no, do not enable thin provisioning.

Parameters description

Parameter Description Example Value

Limit (CPU) Specifies the maximum CPU resource that can be allocated bya server to a VM.

It is the product of the number of configured CPUs and thedominant frequency of the server CPU. The dominantfrequency is automatically obtained by the system.

Default value: 0, which indicates no limit.

If the VMware Hypervisor is used, -1 indicates no limit.

500MHz

CPU Quota Specify the CPU and memory quotas that a VM can obtain inresource contention. The quota indicates the relative priority orimportance of a VM. For example, if the quota of a VM istwice that of another VM, this VM has the priority to use theresources as twice as that of the other VM.

●

High: The quota is 2000 for each CPU and 20 for each MBof memory.

● Medium: The quota is 1000 for each CPU and 10 for eachMB of memory.

● Low: The quota is 500 for each CPU and 5 for each MB of

memory.

For example, if the CPU and memory resource quota is set to

Medium for a VM that has two virtual CPUs and 1 GBmemory, the VM has 2000 CPU quotas (2 x 1000) and 10,240memory quotas (10 x 1024).

Medium

Memory Quota Medium

NOTE


40/73



Reserved(CPU,Memory)

Specifies the minimum CPU and memory resources required by a VM.

● A VM can start only when the server provides the

minimum CPU and memory resources required by the VM.

● If this parameter is specified, the server will provide thereserved CPU and memory resources for the VM even ifthe server is heavily loaded.

For example, if a server has 2 GB memory available and thereserved value is set to 1 GB for VM 1 and VM 2 running onthis server, both VMs can obtain 1 GB memory.

Configuration principles:

● If users have no special requirements on VM performance

indicators, use the default settings.

● If users have special requirements on VM performance

indicators, set this parameters based on user requirements.Value range:

● Reserved CPU: an integer ranging from 0 to the maximum

CPU limit.

● Reserved memory: an integer ranging from 0 to 1024 x

nGB. where n is the configured memory size. For example,if the configured memory is 2 GB, the maximum reservedmemory is 2048 GB.

Default value: 0, which indicates that no resource is reserved.

To install non-ISO application software for a VM template, you need to copy the application software package savedon the PC to the VM in shared mode, and install the package on the VM. Therefore, check that at least one NIC onthe VM belongs to the service plane. That ensures that the VM can be automatically allocated an IP address that cancommunicate with the PC. If the VMware Hypervisor is used, delete the NIC configuration after installing non-ISOapplication software and before publishing the VM template. If the VMware Hypervisor is used, click ChangeStartup Mode to change the startup mode to boot from the CD-ROM drive.

If yes, go to step 11.


Configuring a NIC

Step 11

On the Install Software page, click OK.

The VM Template page is displayed.

Step 12 View the name and owning cluster of the VM template. Close the VM Template page.

Step 13 Click Resource.

The Resource page is displayed.

Step 14 In the navigation tree on the left, select the cluster housing the VM, and click the VM tab page in theright pane.

Step 15 Enter the VM template information in the search field and click Search.

You can click Advanced to search for a VM template with more criteria.

Step 16

Under Operation on the Summary page, click Start/Wake up.

Step 24 You are returned to the Install Software page of the Create VM Template dialog box.

Installing an OS

Step 25 Set the OS parameters about the VM template as prompted based on the data plan.

If the FusionCompute Hypervisor is used, you can mount the CD-ROM drive in shared mode. Alternatively, you

can click VNC login, click on the VM, and then select File (*.iso) to mount the CD-ROM drive. Thisdocument uses the shared mode as an example when describing the detailed steps.

If the VMware Hypervisor is used, CD-ROM drives cannot be mounted using a locally shared file. An NSFserver must be configured in the vCenter to communicate with the FusionManager and mount CD-ROM drives.

If you click Close on the Software Installation page, the system asks you whether to save the VM template being created. If you save the VM template as prompted, the VM information can be searched for on the VM

Template page. To continue the installation, click .

When installing an OS, select Restart the VM immediately after mounting the ISO file.

Step 26

Click Mount.

The Mount dialog box is displayed.

A host allows only one VM template to have a CD-ROM drive mounted. Therefore, if you want to exit the SoftwareInstallation page when no software is being installed for the VM template, click Detach to unmount CD-ROM

drive from the VM first. If the VMware Hypervisor is used and the unmounting fails, click VNC login, eject theCD-ROM drive, and try again.
