Upgrade-Beschreibugen

set fixed amount of mem for dom0 appending following to kernel parameter:
- ```
dom0_mem=512M
```
- also: "The next step is to configure xend to make sure dom0 memory is never ballooned down while starting new guests. This can be done by editing /etc/xen/xend-config.sxp and modifying the "dom0-min-mem" option to (dom0-min-mem 512) and also change the "enable-dom0-ballooning" option to (enable-dom0-ballooning no). These options will make sure xend never takes any memory away from dom0."
