This patch works several files that were not in common use back into the documents they should live with. The intended end result of this activity is to make common as lean as possible so it can be more easily translated. Also: Don't include configdrive table in user-guide since it's not relevant for audience Change-Id: Iacd5c68c639e60e8c711cb18351543e477444299

each of your dom0's

<para>Dom0 space is at a premium so creating a directory

in dom0 is potentially dangerous and likely to fail

especially when you resize large servers. The least

you can do is to symlink <filename>/images</filename>

to your local storage SR. The following instructions

|
work for an English-based installation of XenServer

(and XCP) and in the case of ext3-based SR (with which

the resize functionality is known to work

correctly).</para>
