Creating a Bare VM

Creating a Bare VM

Scenarios

Create a bare VM on FusionCompute.

Full copy, QuickPrep, linked clone, and full memory VM templates are supported in the application virtualization scenario. Table 2-6 provides features of each VM type.

Table 2-6 Features of each VM type

VM Type

Feature

Full copy/QuickPrep

  • No requirements are put on storage virtualization.
  • The memory must be at least 24 GB.
  • For system disks, set Configuration mode to Common.
  • No data disk needs to be added by default. You can add a data disk as required.
  • For user disks, you are advised to set Configuration mode to Thick provisioning lazy zeroed if this option is available.
  • VM software can be updated by modifying a VM template.

Linked clone

  • Virtual storage must be used.
  • You are advised to enable the iCache function.
  • Select the data store that supports Thin provisioning.
  • For system disks, set Configuration mode to Thin provisioning.
  • No data disk needs to be added.
  • VM software can be updated for linked clone templates that are not used to create VMs by modifying VM templates.
  • VM systems can be restored to the initial state with one click.
  • VM systems in a linked clone VM group can be updated using a template.

Full memory

  • IOTailor storage must be selected.
  • For system disks, set Configuration mode to Thin provisioning.
  • No data disk needs to be added.
  • VM software can be updated for full memory templates that are not used to create VMs by modifying VM templates.
  • VM systems can be restored to the initial state with one click.
  • VM systems in a full memory VM group can be updated using a template.

Prerequisites

  • Computing, storage, and network resources required for VM creation are ready.
  • You have logged in to the FusionCompute.

Data

For details about key data and parameters, see the description given in specific procedures.

Procedure

  1. On the FusionCompute portal, choose VM and Template > Getting Started.
  2. Click Create VM.

    The Create VM page is displayed.

  3. Select Create VM, click Next, and set related parameters, as shown in Table 2-7.

    NOTE:
    • You can click before a parameter name to view detailed configuration items of this parameter.
    • Configuration mode:
      • Common: The space configured for the virtual disk is allocated and the data remaining on the physical device is zeroed out when the disk is created. It takes longer to create disks in this mode than to create disks in other modes.
      • Thin provisioning: The system allocates part of the configured disk capacity for the first time, and allocates the rest of the disk capacity based on the storage usage of the disk until all the configured disk capacity is allocated.
      • Thick provisioning lazy zeroed: The space configured for the virtual disk is allocated during the creation of the disk. The data remaining on the physical device is zeroed out only on the first data write from the VM. It takes less time to create disks in this mode than to create disks in Common mode. The I/O performance is higher than the disks in Thin provisioning mode but lower than the disks in Common mode.
    Table 2-7 VM parameter settings

    VM Type

    Category

    Description

    Full copy/QuickPrep

    VM Name

    Name: Specifies the name of the VM to be created, which is user-defined.

    Computing Resource

    Specifies the location where the VM is to be created. The default value ManagementCluster is recommended.

    Data Store Resource

    Select a data store based on the FusionCompute data plan.

    You are advised to use the high-performance storage instead of the low-performance storage, such as NL-SAS and SATA.

    NOTE:

    If you select FusionStorage, you cannot change the storage type to Local disk when you use the template to provision VMs.

    VM Hardware Specification

    The VM hardware specifications are as follows:

    • CPU: Configure at least six CPUs.
    • Memory: Configure at least 24 GB memory.
    • Disks1:
      • Capacity: The OS is installed on the first disk by default. You are advised to set the capacity to 80 GB.
      • Configuration mode: Common.

        For user disks, you are advised to set Configuration mode to Thick provisioning lazy zeroed if this option is available.

    • NICs1: Select a service plane distributed virtual switch (DVS) and port group for the VM.

    The quantities of Disks and NICs are 1 by default. Users can increase the quantities as required.

    Others

    If a VM BSOD occurs, you are advised to restart the VM.

    Retain the default values for other parameters.

    Linked clone

    Data Store Resource

    Select the data store that supports Thin provisioning.

    You are advised to use the high-performance storage instead of the low-performance storage, such as NL-SAS and SATA.

    NOTE:

    If you select FusionStorage, you cannot change the storage type to Local disk when you use the template to provision VMs.

    VM Hardware Specification

    The VM hardware specifications are as follows:

    • CPU: Configure at least six CPUs.
    • Memory: Configure at least 24 GB memory.
    • Disks1:
      • Capacity: The OS is installed on the first disk by default. You are advised to set the capacity to 80 GB.
      • Configuration mode: Set the configuration mode of system disks to Thin Provisioning.
    • NICs1: Select a service plane distributed virtual switch (DVS) and port group for the VM.

    The quantities of Disks and NICs are 1 by default. Users can increase the quantities as required.

    Others

    If a VM BSOD occurs, you are advised to restart the VM.

    Retain the default values for other parameters.

    NOTE:

    You are advised to set Basic Block Storage Settings to No to disable live migration.

    Full memory

    VM Name

    Name: Specifies the name of the VM to be created, which is user-defined.

    Computing Resource
