line assumes that all your nodes have secondary IPs in the |

192.0.2.0/24 network, adjust it accordingly to your setup. |

Besides the ballooning change which you need to set in |
|
205 |
``/etc/xen/xend-config.sxp``, you need to set the memory and nosmp |
|
206 |
parameters in the file ``/boot/grub/menu.lst``. You need to modify |
|
207 |
the variable ``xenhopt`` to add ``dom0_mem=1024M`` like this: |
|
208 |
|
|
209 |
.. code-block:: text |
|

## Xen hypervisor options to use with the default Xen boot option |
|
212 |
# xenhopt=dom0_mem=1024M |
|
213 |
|
|
214 |
and the ``xenkopt`` needs to include the ``maxcpus`` option like |
|
215 |
this: |
|
216 |
|
|
217 |
.. code-block:: text |
|

## Xen Linux kernel options to use with the default Xen boot option |
|
220 |
# xenkopt=maxcpus=1 |
|
221 |
|
|
222 |
Any existing parameters can be left in place: it's ok to have |
|
223 |
``xenkopt=console=tty0 maxcpus=1``, for example. After modifying the |
|
224 |
files, you need to run:: |
|
225 |
|
|
226 |
$ /sbin/update-grub |
|
227 |

If you want to run HVM instances too with Ganeti and want VNC access to |
229 | 203 |
the console of your instances, set the following two entries in |
230 | 204 |
``/etc/xen/xend-config.sxp``: |
