[Qemu-devel] [PATCH] Add configuration variables for iscsi

[Ronnie Sahlberg]

Kevin, List


This is version 2 of the patch to add configuration variables for iSCSI.
This version adds the feature to specify configuration blocks that apply to a 
specific target name, allowing qemu to use different settings if/when 
connecting one guest to multiple different iscsi targets.


This patch adds configuration variables for iSCSI to set
initiator-name to use when logging in to the target,
which type of header-digest to negotiate with the target
and username and password for CHAP authentication.

This allows specifying a initiator-name either from the command line
-iscsi initiator-name=iqn.2004-01.com.example:test
or from a configuration file included with -readconfig
[iscsi]
 initiator-name = iqn.2004-01.com.example:test
 header-digest = CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
 user = CHAP username
 password = CHAP password

In the configuration file it is also possible to set a target specific
configuratyion block using the header
[iscsi "iqn.target.name"]

When a iscsi session is initialized, it will first try to use a configuration
section that matches the target name.
If no such block is found, it will fall-back to try the default [iscsi] section 
instead.
