Dear orthohin ,
please follw the steps to change the SCSI controller
To change a virtual machine's SCSI controller when the guest operating system is already installed:
- Power down the virtual machine.
- Right-click the virtual machine and click Edit Settings.
- Click the SCSI controller.
- Click Change Type.
- Select the controller type and click OK.
- Click OK to finish editing the properties of the virtual machine.
- Power on the virtual machine.
If the virtual machine fails to boot:
- Power down the virtual machine
- Change the first controller back to the original SCSI controller.
- Add a new hard disk. When choosing the Virtual Device Node, select SCSI (1:0).
Note: When the virtual disk is created, it creates a second virtual SCSI controller. - Select the second virtual SCSI controller.
- Click Change Type.
- Select the controller type and click OK.
- Click OK to finish editing the properties of the virtual machine.
- Power on the virtual machine.
- After the operating system boots, log in to the virtual machine. The operating system automatically detects the new SCSI controller and adds the appropriate drivers.
- Power down the virtual machine.
- Remove the added virtual disk. The controller is removed automatically.
- Change the first virtual controller to the desired setting.
- Power on the virtual machine.
