+The password must be set separately using the @code{set_password} command in

+@code{set_password <protocol> <password>} where <protocol> could be either
+"vnc" or "spice".
+
+If you would like to change <protocol> password expiration, you should use
+@code{expire_password <protocol> <expiration-time>} where expiration time could
+be one of the following options: now, never, +seconds or UNIX time of
+expiration, e.g. +60 to make password expire in 60 seconds, or 1335196800
+to make password expire on "Mon Apr 23 12:00:00 EDT 2012" (UNIX time for this

Syntax for specifying iSCSI LUNs is
``iscsi://<target-ip>[:<port>]/<target-iqn>/<lun>''
+By default qemu will use the iSCSI initiator-name
+'iqn.2008-11.org.linux-kvm[:<name>]' but this can also be set from the command
+line or a configuration file.
+

Example (without authentication):
@example
qemu-system-i386 -iscsi initiator-name=iqn.2001-04.com.example:my-initiator \

+Don't create default devices. Normally, QEMU sets the default devices like serial
