5.8 Sparse Image Files and Disk Space

If the host's physical disk reaches a state where it has no available space, a virtual ma-
chine using a virtual disk based on a sparse image file is unable to write to its disk.
Consequently, it reports I/O errors.
The Reiser file system, perceiving a corrupt disk environment, automatically sets the
file system to read-only. If this situation happens, you should free up available space
on the physical disk, remount the virtual machine's file system, and set the file system
back to read-write.
To check the actual disk requirements of a sparse image file, use the command du -h
<image file>.

5.9 Virtual Keyboards

When a virtual machine is started, the host creates a virtual keyboard that matches the
keymap entry according to the virtual machine's settings. If there is no keymap entry
in the virtual machine's settings, the host uses the keymap entry specified in host's
xend file ( xend-config.sxp). If there is no keymap entry in either the host's
xend file or the virtual machine's settings, the virtual machine's keyboard defaults to
English (US).
Unless you manually specify it, a keymap entry is not specified in the host's xend file
or for any virtual machine. Therefore, by default, all virtual machine settings use the
English (US) virtual keyboard. It is recommended that you specify a keymap setting
for xend and for each virtual machine, especially, if you want to migrate virtual machines
to different hosts
To view a virtual machine's current keymap entry, enter the following command on
