[libvirt] Libvirt iSCSI APIs
by Ata Bohra
Hi All,
I am interested in extending libvirt APIs to support iSCSI operations such as: add/remove targets, list targets, list remote LUNs, rescan luns etc. The intention is to provide an interface that external programs can hook to manage iSCSI storage devices on a given hypervisor(I would be adding interfaces for ESX first). Looking at the libvirt.c interface for storage driver I'm unable find routines that can be overridden for specific hypervisor. Googling lead to a nice blog presentation that provisions VMs on remote LUN(s) for KVM but uses virish. (http://berrange.com/tags/iscsi/).
My question is; is this as per design not to expose iSCSI related APIs? Will an extention to libvirt.c (_virStorageDriver) so that every hypervisor can implement it is acceptable? Please correct me if I am missing something serious here.
Thanks!

[libvirt] [PATCH] Fix daemon auto-spawning
by Christophe Fergeau
Commit 32a9aac switched libvirt to use the XDG base directories
to locate most of its data/config. In particular, the per-user socket
for qemu:///session is now stored in the XDG runtime directory.
This directory is located by looking at the XDG_RUNTIME_DIR environment
variable, with a fallback to ~/.cache/libvirt if this variable is not
set.
When the daemon is autospawned because a client application wants
to use qemu:///session, the daemon is ran in a clean environment
which does not contain XDG_RUNTIME_DIR. It will create its socket
in ~/.cache/libvirt. If the client application has XDG_RUNTIME_DIR
set, it will not look for the socket in the fallback place, and will
fail to connect to the autospawned daemon.
This patch adds XDG_RUNTIME_DIR to the daemon environment before
auto-starting it. I've done this in virNetSocketForkDaemon rather
than in virCommandAddEnvPassCommon as I wasn't sure we want to pass
these variables to other commands libvirt spawns. XDG_CACHE_HOME
and XDG_CONFIG_HOME are also added to the daemon env as it makes use
of those as well.

[libvirt] dnsmasq SRV/TXT RR and Host xml parsing upgrade and bug fix
by Guannan Ren
The set of patches aims to three kind of jobs.
First, for SRV RR, in order to strictly comform to RFC 2782, the patch
changed and upgraded codes in following parts.
The format of SRV RR:
_Service._Proto.Name TTL Class SRV Priority Weight Port Target
1,The protocol and service labels are prepended with an underscore.
e.g: _ldap._tcp.example.com
2,The range of Port,Priority,Weight is 0-65535.
3,A Target of "." means that the service is decidedly not available at this domain.
Also, trying to invoke dnsmasq command line based on its manpage.
--srv-host=<_service>.<_prot>.[<domain>],[<target>[,<port>[,<priority>[,<weight>]]]]
_service and protocol are mandatory options.
The reset of them are optional.
When the target is not given in dnsmasq, it comform to the third item above.
For TXT RR, we changed the text field from mandatory to optional based on
dnsmasq manpage:
--txt-record=<name>[[,<text>],<text>]
Second, changed the way of dns element as well as its children elements parsing via
virXPathNodeSet(). It has advantages when multiple children elements there is.
Third, fixed related bug and unexposed bugs

[libvirt] [PATCHv2] fix failure when building with --disable-debug

When building with --disable-debug, VIR_DEBUG expands to a nop.
But parameters to VIR_DEBUG can be variables that are passed only
to VIR_DEBUG. In the case the building system complains about unused
variables.

[libvirt] [PATCH 0/6] Add usb controller model="none"
by Peter Krempa
This series adds support for completely disabling USB bus for a host if a user
requires this. For this to work a new USB controller model "none" was added
that removes the USB bus.
The controller is added in patches 2-4. Patch 1 cleans up some nits (and is not
necessary) and patches 5 and 6 tweak qemuxml2argvtest and add tests to check the
new controller.
Peter Krempa (6):
maint: Clean up coding style
domain_conf: Add USB controler model "none"
domain_conf: Add helpers to verify if device configuration is valid
qemu: Add support for "none" USB controller
tests: Add support for cathing domain XML parsing errors
tests: Add tests to check the new USB "none" controller
