The uninstall
parameter is added automatically and specifies that the Hypervisor is to be uninstalled.
Optionally, add the storage_init
parameter to the end of the kernel
command string.
The storage_init
parameter specifies the device on which the Hypervisor resides. During uninstallation, it specifies the device from which the Hypervisor should be removed. If the Hypervisor is installed to the /dev/sda/
device, you can specify that this device is cleaned by including the following at the end of the kernel
command string:
storage_init=/dev/sda
If this parameter is not included, the Hypervisor's location is detected automatically.
Press Enter to save any changes to the kernel
string, for this boot only, and display the previous screen.
Press Enter to boot the Hypervisor. The Hypervisor will uninstall itself immediately. Once the Hypervisor has been removed the system will reboot.
The Red Hat Enterprise Virtualization Hypervisor has been removed from the specified device.
