[PATCH] Plan9fs (aka 9pfs, VirtFS) support for QEMU/KVM environment
by Deepak C Shetty
VirtFS is virtualization aware file system pass-through which provides the
functionality to share host file system inside the guest. Its supported in
libvirt via the <filesystem> xml node/tag. This patch introduces the
filesystem support in KVM_DiskRASD and its associated changes needed to
support VirtFS in libvirt-cim.
For further details...
Virtfs home page/wiki : http://v9fs.sourceforge.net/
Virtfs setup for QEMU : http://wiki.qemu.org/Documentation/9psetup
Virtfs support in libvirt :
http://libvirt.org/formatdomain.html#elementsFilesystems
An example of the <filesystem> node in libvirt, supporting VirtFS...
<filesystem type='mount' accessmode='passthrough'>
<driver type='path'/>
<source dir='/export/to/guest'/>
<target dir='/import/from/host'/>
<readonly/>
</filesystem>

[PATCH v6 0/3] Implementation of a linked list helper
by Eduardo Lima (Etrunko)
From: "Eduardo Lima (Etrunko)" <eblima(a)br.ibm.com>
This series provides a generic linked list implementation for libxkutil that is
based on the one originally developed for the libvirt domain events support
recently integrated upstream.
As test case I ported the ComputerSystemIndication provider code to use this
list implementation. In the near future it will be also used by the event loop
that I am currently working on to allow systems with libvirt older than 0.9.0
to make use of the same feature.
Other possible use cases would be to port the code of libxkutil/*_parsing* to
also use the list implementation instead of static arrays.
Changes from v5:
- Fix possible NULL dereference in list_first()
Changes from v4:
- Fix possible NULL dereference in list_last_node()
- Fix possible leak in acl_parsing.c
Changes from v3:
- Fix crashes in list_free(), list_first_node() and list_count()
- Include patch that ports the acl filter ref code to use the linked list
implementation
Changes from v2:
- Make list struct private
Changes from v1:
- Fix version iformation in Makefile.am

[PATCH v4] Fix AppliedFilterList creation and deletion
by Chip Vincent
From: Chip Vincent <cvincent(a)us.ibm.com>
Fixes many small issues with the current AppliedFilterList provider.
1) Fix Create to properly return a complete object path and fix Delete to
properly parse that path.
2) Persist applied filer rules. Since it's not possible to dyanmically update
a single device, I've changed the code to modify and re-define the VM to
essentially add/remove ACL filter associations.
I also updated the code to minimize domain/device parsing overhead. For
some strange reason, our internal APIs sometimes take a virDomainPtr and
other times a struct domain * forcing providers who work with domains
*and* devices to parse everything twice. Until the internal APIs are
cleaned up, I simply parse everything once and then fetch the device
manually from the struct domain *.
3) Add VIR_DOMAIN_XML_INACTIVE to virDomainGetXML(). By default, libvirt only
returns the XML of the running domain. We need to fetch the *stored* XML
that will be used for the next boot so that all changes made while the VM
is running are preserved.
Changes from v3:
- Fix NestedFilterList DeleteInstance
- Fix remove_filter_ref() in acl_parsing.c (intend to refactor in
future patch)
Changes from v2:
- Return the correct reference in NestedFilterList
Changes from v1:
- Fix leak and other comments
- Fix all cases virDomainGetXML()
- Fix NestedFilterList Create/Delete instance

[PATCH v3 0/2] Implementation of a linked list helper
by Eduardo Lima (Etrunko)
From: "Eduardo Lima (Etrunko)" <eblima(a)br.ibm.com>
This series provides a generic linked list implementation for libxkutil that is
based on the one originally developed for the libvirt domain events support
recently integrated upstream.
As test case I ported the ComputerSystemIndication provider code to use this
list implementation. In the near future it will be also used by the event loop
that I am currently working on to allow systems with libvirt older than 0.9.0
to make use of the same feature.
Other possible use cases would be to port the code of libxkutil/*_parsing* to
also use the list implementation instead of static arrays.
Changes from v2:
- Make list struct private
Changes from v1:
- Fix version iformation in Makefile.am

libxkutil: Linked list helper
CSI: Use list helper implementation

[PATCH V6 7/7] vlan extention - CIM model add EASD
by xiaxia347work＠163.com
From: Wenchao Xia <xiawenc(a)linux.vnet.ibm.com>
Add EASD for EthernetPort. According DSP1097, There are two kinds of EASD:
EA stands for Settings of EthernetPort, EC stands for Settings for Connection
between EthernetPort.
