[libvirt] FOSDEM 2017: Call For Proposals -- Virtualization & IaaS DevRoom
by Kashyap Chamarthy 11 Nov '16

11 Nov '16

======================================================================= The call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2017, to be hosted on February 4, 2017. This year will mark FOSDEM’s 17th anniversary as one of the longest-running free and open source software developer events, attracting thousands of developers and users from all over the world. FOSDEM will be held once again in Brussels, Belgium, on February 4 & 5, 2017. --------------- Important Dates --------------- Submission deadline: 18 November 2016 Acceptance notifications: 04 December 2016 Final schedule announcement: 11 December 2016 Devroom: 04 February 2017 (one day) ----------------- About the Devroom ----------------- The Virtualization & IaaS devroom will feature session topics such as open source hypervisors and virtual machine managers such as Xen Project, KVM, QEMU, bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as Apache CloudStack, OpenStack, oVirt, OpenNebula, and Ganeti. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM. -------------------- Submit Your Proposal -------------------- All submissions must be made via the Pentabarf event planning site. https://penta.fosdem.org/submission/FOSDEM17 If you have not used Pentabarf before, you will need to create an account. If you submitted proposals for FOSDEM in previous years, you can use your existing account. After creating the account, select Create Event to start the submission process. Make sure to select Virtualisation and IaaS devroom from the Track list. Please fill out all the required fields, and provide a meaningful abstract and description of your proposed session. --------------------- Submission Guidelines --------------------- - We expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. - All presentation slots are 45 minutes, with 35 minutes planned for presentations, and 10 minutes for Q&A. - All presentations will be recorded and made available under Creative Commons licenses. In the Submission notes field, please indicate that you agree that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license and that you agree to have your presentation recorded. For example: "If my presentation is accepted for FOSDEM, I hereby agree to license all recordings, slides, and other associated materials under the Creative Commons Attribution Share-Alike 4.0 International License. Sincerely, <NAME>." - In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. (Sadly, we are not able to offer travel funding for prospective speakers.) ------------------- Call for Volunteers ------------------- We are also looking for volunteers to help run the devroom. We need assistance watching time for the speakers, and helping with video for the devroom. Please contact Brian Proffitt (bkp at redhat.com) for more information. ---------- Questions? ---------- If you have any questions about this devroom, please send your questions to our devroom mailing list. iaas-virt-devroom(a)lists.fosdem.org You can also subscribe to the list to receive updates about important dates, session announcements, and to connect with other attendees. ======================================================================= -- /kashyap

[libvirt] [PATCH] qemu: fix one reboot scenario
by Maxim Nestratov 11 Nov '16

11 Nov '16

Both qemuDomainReboot and qemuDomainShutdownFlags do the following if they were called to reboot: 1. use agent and call qemuAgentShutdown 2. then if the above function doesn't succeed, try qemuMonitorSystemPowerdown When the first step is called, it resets fakeReboot flag, while the second one, opposite to that, sets it. Thus, in case we tried to use agent to reboot a guest and failed for some reason, we end up with fakeReboot flag set. After that, as qemuMonitorSystemPowerdown function was called, libvirt is notified with POWERDOWN. The problem is that there is no callback routine set for it. The lack of monitor event reaction leads to incorrect logic and guest doesn't restart or reboot correctly. The patch simply sets domainPowerdown monitor callback to qemuProcessHandleShutdown as powerdown event processing is actually equal to shutdown.
