Oracle VirtualBox Problem Solving case

Oracle VirtualBox Problem Solving case

1. When the VM is turned on, the hard disk UUID already exists:
Error message:

Cannot register the hard disk 'f: \ VirtualBox VMs \ cl-11r2-rac2 \ cl-11r2-rac2.vdi '{cc59aac5-a2e6-4f39-b441-04d1ff29acd2} because a hard disk' F: \ VirtualBox VMs \ cl-11r2-rac1 \ cl-11r2-rac1.vdi 'with UUID {cc59aac5-a2e6-4f39-b441-04d1ff29acd2} already exists.

Solution:

Go to the installation directory of cmd cd to VirtualBox:

Cd C: \ Program Files \ Oracle \ VirtualBox

Specify the physical file (vbox Virtual Disk File) and run the following command:

VBoxManage internalcommands sethduuid "F: \ VirtualBox VMs \ cl-11r2-rac2 \ cl-11r2-rac2.vdi"
UUID changed to: 7db19c60-8c71-456b-a81c-d263a4988230

After the change is successful, delete * in the vbox Virtual Disk File directory *. vbox-prev file and C: \ Users \ Administrator \. virtualBox in VirtualBox. xml and VirtualBox. xml-prev file, use NotePad to open *. modify the following information in the vbox file:

<MediaRegistry>
<HardDisks>
<HardDisk uuid = "{bfdcadf6-b88d-4224-a5ff-673f1ca3f413}" location = "cl-11r2-rac2.vdi" format = "VDI" type = "Normal"/>
Changed:
<HardDisk uuid = "{7db19c60-8c71-456b-a81c-d263a4988230}" location = "cl-11r2-rac2.vdi" format = "VDI" type = "Normal"/>
</HardDisks> <DVDImages/> <FloppyImages/>
</MediaRegistry>

Locate the </StorageControllers> node.
<AttachedDevice type = "HardDisk" port = "0" device = "0">
<Image uuid = "{bfdcadf6-b88d-4224-a5ff-673f1ca3f413}"/> to: <Image uuid = "{7db19c60-8c71-456b-a81c-d263a4988230}"/>
</AttachedDevice>

When there are multiple disks, pay attention to the disk sequence. Generally, the port of the VM's primary disk is "0 ";
Delete C: \ Users \ Administrator \. virtualBox in VirtualBox. xml and VirtualBox. xml-prev file, because by default, the virtual machine will read these two files when opening, update and synchronize *. vbox and *. the vbox-prev file will overwrite the modified content and the modification will be invalid.
