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 le is unable to write to its disk.
Consequently, it reports I/O errors.
The Reiser le system, perceiving a corrupt disk environment, automatically sets the
le system to read-only. If this situation happens, you should free up available space
on the physical disk, remount the virtual machine’s le system, and set the le system
back to read-write.
To check the actual disk requirements of a sparse image le, 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 specied in host’s
xend le ( xend-config.sxp). If there is no keymap entry in either the host’s
xend le 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 specied in the host’s xend le
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
