Configuring the boot process
Specify the device that contains a root file system, or a prepared kernel image file.
Before you begin
About this task
When you start a virtual server, an Initial Program
Load (IPL) is performed to boot the guest. You specify the
boot process in the domain configuration-XML file:
- If a guest is
installed, you usually boot it from a disk.
You specify the boot device as described in Configuring a virtio block device as IPL device.
- Alternatively, you can specify an ISO image or an initial ramdisk and a
kernel image file for a guest IPL.
For a description, see Configuring an ISO image as IPL device or Configuring a kernel image file as IPL device.
You can use the chreipl command on the guest to configure alternative reboot devices.
You can use the virt-xml command to start the virtual server and boot the guest from an alternative boot device, see Booting from a temporary boot device.
