V2V Conversion Host

Before you can perform V2V migration, specify a host in the destination cluster as the V2V conversion host.

Add a V2V Conversion Host

On the main menu of ZStack Cloud, choose Platform O&M > Migration Service > V2V Conversion Host. On the V2V Conversion Host page, click Add V2V Conversion Host. Then, the Add V2V Conversion Host page is displayed.

On the displayed page, set the following parameters:
  • Name: Enter a name for the V2V conversion host.

    Note that the name must be 1 to 128 characters in length and can contain Chinese characters, letters, digits, hyphens (-), underscores (_), periods (.), parenthesis (), colons (:), and plus signs (+).

  • Description: Optional. Enter a description for the V2V conversion host.
  • Type: Select a V2V conversion host type, including VMware and KVM.
    Note: The type of the V2V conversion host must be consistent with that of the source cloud platform.
  • Host: Select a host from the destination cluster as the V2V conversion host.
    Note: A host cannot be used as a V2V conversion host for both the VMware platform type and the KVM platform type at the same time.
  • Cache Path: Enter a local path on the V2V conversion host as the storage path.
    Note: During the V2V migration, the VM system and data are first cached in the V2V conversion host and then imported into the target primary storage.
  • Migration Network: Optional. If you deployed an independent network for V2V migration, enter the CIDR of the network.
    Note:
    • If you deployed an independent network for V2V migration, you could add the network to the Cloud directly.
    • In a V2V migration scenario, the migration network is used to convert data migrated from the destination primary storage to the V2V conversion host.
    • Using an independent migration network can avoid network congestion and improve transmission efficiencies.
    • If not set, the management network will be used by default for V2V migration.
  • Upstream Bandwidth: Optional. Set the upstream bandwidth of the V2V conversion host. This parameter limits the speed of uploading data from the V2V conversion host to the destination primary storage. The upstream bandwidth must be an integer ranging from 1 Mbps to 32 Gbps. Unit: Mbps and Gbps.
  • Downstream Bandwidth: Optional. Set the downstream bandwidth for the V2V conversion host. This parameter limits the speed of downloading data from the source primary storage to the V2V conversion host. The downstream bandwidth must be an integer ranging from 1 Mbps to 32 Gbps. Unit: Mbps and Gbps.

V2V Conversion Host Details

On the main menu of ZStack Cloud, choose Platform O&M > Migration Service > V2V Conversion Host. On the V2V Conversion Host page, click on the name of a V2V conversion to go to the details page. The details page displays the basic information, monitoring data, and configurations of the V2V conversion host.

Manage a V2V Conversion Host

On the main menu of ZStack Cloud, choose Platform O&M > Migration Service > V2V Conversion Host. Then, the V2V Conversion Host page is displayed.

The following table lists the actions that you can perform on a V2V conversion host.
Action Description
Edit V2V Conversion Host Modify the name and description of the V2V conversion host.
Enable V2V Conversion Host Enable a V2V conversion host.
Disable V2V Conversion Host Disable a V2V Conversion host.
Note: If you disable a V2V conversion host when you perform a V2V job, the job is not affected.
Set Network Bandwidth Set the upstream or downstream bandwidth of the V2V conversion host.
Delete V2V Conversion Host Delete a V2V conversion host.
Note:
  • Deleting a V2V conversion host automatically cancels the ongoing V2V job.
  • Deleting a V2V conversion host also deletes the local records of the backup data on the conversion host, but the actual data is not affected. If you add this conversion host again, the local records are not recovered automatically.

Considerations

  • A V2V conversion host must have sufficient hardware resources, such as network bandwidth and disk space. The following table lists the minimum configuration requirements.
    Table 1. Minimum Configuration Requirements for V2V Conversion Host
    Hardware Configuration Requirements
    CPU Minimum 8 cores
    Memory Minimum 16 GB
    Network Minimum 1 Gigabyte NIC
    Storage Minimum 50 GB for the rest of storage spaces
    Note: You can modify the storage configuration according to the number of VM instances to be migrated.
  • The type of the V2V conversion host must be consistent with that of the source cloud platform.
  • You can set an independent migration network and a network QoS for a V2V conversion host to control transmission bottlenecks and to improve migration efficiencies.
