For optimum performance when running both CPU and I/O intensive
|
| 173 |
173 |
instances, it's also recommended that the dom0 is restricted to one CPU
|
| 174 |
|
only, for example by booting with the kernel parameter ``maxcpus=1``.
|
|
174 |
only. For example you can add ``dom0_max_vcpus=1,dom0_vcpus_pin`` to your
|
|
175 |
kernels boot command line and set ``dom0-cpus`` in
|
|
176 |
``/etc/xen/xend-config.sxp`` like this::
|
|
177 |
|
|
178 |
(dom0-cpus 1)
|

It is recommended that you disable xen's automatic save of virtual
|
| 177 |
181 |
machines at system shutdown and subsequent restore of them at reboot.

``ssh-keygen``). Finally execute::
