4.5.2. Boot Modes

Booting via the BIOS is available for hypervisors supporting full virtualization. In this case the BIOS has a boot order priority (floppy, harddisk, cdrom, network) determining where to obtain/find the boot image.

Example 4.38. Setting the Boot Mode

<domain>
 ...
  <os>
    <type>hvm</type>
    <loader readonly='yes' type='rom'>/usr/lib/xen/boot/hvmloader</loader>
    <nvram template='/usr/share/OVMF/OVMF_VARS.fd'>/var/lib/libvirt/nvram/guest_VARS.fd</nvram>
    <boot dev='hd'/>
    <boot dev='cdrom'/>
    <bootmenu enable='yes' timeout='3000'/>
    <smbios mode='sysinfo'/>
    <bios useserial='yes' rebootTimeout='0'/>
  </os>
  ...
</domain>
