Create a virtual machine

After the installation of the system, the mouse will be misplaced and two mice will be displayed, so the display mode will first choose the default and install the driver spice-guest-tools-latest.exe.

Install common software, system configuration, optimization, shutdown

Change the virtual machine hardware through the web interface and change the display mode to spice

2. The final configuration of the virtual machine is shown in the following figure:

3. Log in to the host where the virtual machine is located on the command line

Execute the following command:

# cd / etc/pve/nodes/pve5/qemu-server (host where the virtual machine resides)

# qm showcmd 100 > / root/100.sh (100 represents the virtual machine number)

# vi 100.sh

Modify the configuration information in the script to find the line-spice

Modified to:

-spice 'port=61002,addr=0.0.0.0,seamless-migration=on,password=12345'

Note: the default configuration file is tls-port, which should be changed to port

Password authentication can be performed by password, and password authentication can be removed by disable-ticketing parameter.

Tls-ciphers=HIGH. This parameter in the generated sh should be removed.

When the addr is changed to the virtual machine IP address, the sh cannot be executed successfully, but if it is changed to 0.0.0.0 the virtviewer can only be connected through the host IP.

4. Run the modified script

# / bin/sh 100.sh

After the script runs successfully, there is no prompt, and then the virtual machine is started automatically

Note: be sure to start the virtual machine through a script, otherwise port 61002 cannot be used

5. Check the port situation.

# netstat-anp | grep-v unix to check whether port 61002 is listening

# apt install net-tools (install net tool)

Port is normal:

6. Use spice client to test

Install spice client software virt-viewer-x64-8.0 on any host in the intranet

Connect to the virtual machine. Ip is the host address and port is 61002 (you can also change the addr=0.0.0.0 in the script to virtual machine IP)

Will be prompted for a password: 12345

Login succeeded

7. Thin client configuration

Connect the thin client to the local area network, select spice for the connection protocol, fill in "connection name:", "server address (host address)", "spice service listening port (virtual machine profile setting is 61002)", "password (virtual machine configuration file setting), etc., and then you can connect.

8. Modify the virtual machine configuration file to realize the virtual desktop function.

# vi / etc/pve/nodes/pve5/qemu-server/100.conf pve5 is the host where the virtual machine resides

Just add the following to the first line:

Args:-spice 'port=61002,addr=0.0.0.0,seamless-migration=on,password=123456'

Note:

1) multiple virtual machines can be quickly configured by this method, and the virtual machines can still be connected without booting through sh.

2) if multiple virtual machines are started on the same host, each virtual machine should be configured with a different port number

3) if addr is changed to virtual machine IP, the virtual machine will not start.

9. Add sound card equipment

Edit the virtual machine configuration file by adding the following:

# vi / etc/pve/nodes/pve5/qemu-server/100.conf

Args:-device intel-hda,id=sound5,bus=pci.0,addr=0x18-device hda-micro,id=sound5-codec0,bus=sound5.0,cad=0-device hda-duplex,id=sound5-codec1,bus=sound5.0,cad=1-spice 'port=61002,addr=0.0.0.0,seamless-migration=on,password=123456'

(the spice paragraph can be followed.)

Restart the virtual machine, you can see the sound card device, if you can not make sound, you can reinstall the spice-agent driver, update the sound card driver. In addition, virt-viewer-5.0 supports the sound card best, and 8.0 will cause the problem that the sound will be paused and cannot be played.
