-.. admonition:: Debian
-
- Besides the ballooning change which you need to set in
- ``/etc/xen/xend-config.sxp``, you need to set the memory and nosmp
- parameters in the file ``/boot/grub/menu.lst``. You need to modify
- the variable ``xenhopt`` to add ``dom0_mem=1024M`` like this:
-
- .. code-block:: text
-
- ## Xen hypervisor options to use with the default Xen boot option
- # xenhopt=dom0_mem=1024M
-
- and the ``xenkopt`` needs to include the ``maxcpus`` option like
- this:
-
- .. code-block:: text
-
- ## Xen Linux kernel options to use with the default Xen boot option
- # xenkopt=maxcpus=1
-
- Any existing parameters can be left in place: it's ok to have
- ``xenkopt=console=tty0 maxcpus=1``, for example. After modifying the
- files, you need to run::
-
- $ /sbin/update-grub
-
