[libvirt] [PATCH v4 0/3] BSD implementation of virNetDevTapCreate() and virNetDevTapDelete()
by Roman Bogorodskiy
Changes from v3:
* Include linux/if.h header fix so it won't lost why Eric is on vacation
* Fix struct virIfreq definition in case when HAVE_STRUCT_IFREQ is not
defined (thanks to Laine Stump for noticing that)
Roman Bogorodskiy (3):
Make virNetDevSetupControl() public.
BSD: implement virNetDevTapCreate() and virNetDevTapDelete()
portability: use net/if.h instead of linux/if.h

[libvirt] [libvirt-php PATCH 0/2] Block job wrappers and possibility to start VM in paused state
by Tiziano Müller
Following are two patches extending the PHP wrapper a bit:
* first patch adds wrappers for virDomainGetBlockJobInfo and virDomainBlockPull
* second patch makes it possible to start a VM in paused state to start a
Qemu-process for the virDomainBlockPull if no VM is running
Best,
Tiziano
Tiziano Müller (2):
Add wrappers for virDomainGetBlockJobInfo and virDomainBlockPull.
Add optional flags parameter to domain_create

[libvirt] KVM Forum 2013 Call for Participation
by KVM-Forum-2013-PC＠redhat.com
=================================================================
KVM Forum 2013: Call For Participation
October 21-23, 2013 - Edinburgh International Conference Centre - Edinburgh, UK
(All submissions must be received before midnight July 21, 2013)
=================================================================
KVM is an industry leading open source hypervisor that provides an ideal
platform for datacenter virtualization, virtual desktop infrastructure,
and cloud computing. Once again, it's time to bring together the
community of developers and users that define the KVM ecosystem for
our annual technical conference. We will discuss the current state of
affairs and plan for the future of KVM, its surrounding infrastructure,
and management tools. The oVirt Workshop will run in parallel with the
KVM Forum again, bringing in a community focused on enterprise datacenter
virtualization management built on KVM. For topics which overlap we will
have shared sessions. So mark your calendar and join us in advancing KVM.
http://events.linuxfoundation.org/events/kvm-forum/
Once again we are colocated with The Linux Foundation's LinuxCon Europe.
KVM Forum attendees will be able to attend oVirt Workshop sessions and
are eligible to attend LinuxCon Europe for a discounted rate.
http://events.linuxfoundation.org/events/kvm-forum/register
We invite you to lead part of the discussion by submitting a speaking
proposal for KVM Forum 2013.
http://events.linuxfoundation.org/cfp
Suggested topics:
KVM/Kernel
- Scaling and performance
- Nested virtualization
- I/O improvements

SUBMISSION REQUIREMENTS
Abstracts due: July 21, 2013
Notification: August 1, 2013
Please submit a short abstract (~150 words) describing your presentation
proposal. In your submission please note how long your talk will take.
Slots vary in length up to 45 minutes. Also include in your proposal
the proposal type -- one of:
- technical talk
- end-user talk
- birds of a feather (BOF) session
Submit your proposal here:
http://events.linuxfoundation.org/cfp
You will receive a notification whether or not your presentation proposal
was accepted by Aug 1st.
END-USER COLLABORATION
One of the big challenges as developers is to know what, where and how
people actually use our software. We will reserve a few slots for end
users talking about their deployment challenges and achievements.
If you are using KVM in production you are encouraged submit a speaking
proposal. Simply mark it as an end-user collaboration proposal. As an
end user, this is a unique opportunity to get your input to developers.
BOF SESSION
We will reserve some slots in the evening after the main conference
tracks, for birds of a feather (BOF) sessions. These sessions will be
less formal than presentation tracks and targetted for people who would
like to discuss specific issues with other developers and/or users.
If you are interested in getting developers and/or uses together to
discuss a specific problem, please submit a BOF proposal.
HOTEL / TRAVEL
The KVM Forum 2013 will be held in Edinburgh, UK at the Edinburgh
International Conference Centre.
http://events.linuxfoundation.org/events/kvm-forum/hotel
Thank you for your interest in KVM. We're looking forward to your
submissions and seeing you at the KVM Forum 2013 in October!
Thanks,
-your KVM Forum 2013 Program Committee

[libvirt] [PATCH] remote: Forbid default "/session" connections when using ssh transport
by Peter Krempa
Without the socket path explicitly specified, the remote driver tried to
connect to the "/system" instance socket even if "/session" was
specified in the uri. With this patch this configuration now produces an
error.
It is still possible to initiate a session connection with specifying
the path to the socket manually and also manually starting the session
daemon. This was also possible prior to this patch,
This is a minimal fix. We may decide to support remote session
connections using ssh but this will require changes to the remote driver
code so this fix shouldn't cause regressions in the case we decide to do
that.

[libvirt] [PATCH] Implement dispose method for libxlDomainObjPrivate
by Frediano Ziglio
When creating a timer/event handler reference counting is used. So it could
be possible (in theory) that libxlDomainObjPrivateFree is called with
reference counting >1. The problem is that libxlDomainObjPrivateFree leave
the object in an invalid state with ctx freed (but still having dandling
pointer). This can lead timer/event handler to core.
This patch destroy the object before disposing it so at timer/event object
is still valid.
