Import a Linux Virtual Machine with Ubuntu from an External Platform¶

This page provides a detailed introduction on how to import Linux virtual machines from the external platform VMware into the virtual machines of DCE 5.0 through the command line.

Fetch Basic Information of vSphere Virtual Machine¶

• vSphere URL: Fetch information on the URL of the target platform

• vSphere SSL Certificate Thumbprint: Need to be fetched using openssl

  openssl s_client -connect 10.64.56.11:443 </dev/null | openssl x509 -in /dev/stdin -fingerprint -sha1 -noout
  

  Output will be similar to:

  Can't use SSL_get_servername
  depth=0 CN = vcsa.daocloud.io
  verify error:num=20:unable to get local issuer certificate
  verify return:1
  depth=0 CN = vcsa.daocloud.io
  verify error:num=21:unable to verify the first certificate
  verify return:1
  depth=0 CN = vcsa.daocloud.io
  verify return:1
  DONE
  sha1 Fingerprint=C3:9D:D7:55:6A:43:11:2B:DE:BA:27:EA:3B:C2:13:AF:E4:12:62:4D  # Value needed
  

• vSphere Account: Fetch account information for vSphere, and pay attention to permissions

• vSphere Password: Fetch password information for vSphere

• UUID of the virtual machine to be imported: Need to be fetched on the web page of vSphere

  • Access the Vsphere page, go to the details page of the virtual machine to be imported, click Edit Settings , open the browser's developer console at this point, click Network -> Headers , find the URL as shown in the image below.

  • Click Response , locate vmConfigContext -> config , and finally find the target value uuid .

• Path of the vmdk file of the virtual machine to be imported

Network Configuration¶

Different information needs to be configured based on the chosen network mode. If a fixed IP address is required, you should select the Bridge network mode.

• Create a Multus CR of the ovs type. Refer to Creating a Multus CR.

• Create subnets and IP pools. Refer to Creating Subnets and IP Pools.

  apiVersion: spiderpool.spidernet.io/v2beta1

Access VNC to verify successful operation¶

1. Modify the network configuration of the virtual machine

2. Check the current network

   When the actual import is completed, the configuration shown in the image below has been completed. However, it should be noted that the enp1s0 interface does not contain the inet field, so it cannot connect to the external network.

   

3. Configure netplan

   In the configuration shown in the image above, change the objects in ethernets to enp1s0 and obtain an IP address using DHCP.

   

4. Apply the netplan configuration to the system network configuration

   sudo netplan apply
   

5. Perform a ping test on the external network

   

6. Access the virtual machine on the node via SSH.
