I hope to see some of it in coming versions of QEMU, while we work on other improvements to this critical feature.</div><div>- Attended a presentation on the status of ARM on Fedora and CentOS[14]. Seems like a great positive effort, but the road is still long for complete support. Would be cool to support ARM based hosts running virtual machines!</div><div>- Attended a presentation on native vs. threads implementation performance in QEMU[4]. The results were not conclusive, though some improvements in native brought it close to or better in some cases to threads. Seems that our default of heuristic for threads in file-based storage and native in block based storage is fine for the time being, but we'll watch closely for developments in this area.</div><div>- Attended a presentation on debugging qemu (mainly) in OpenStack[5] - I think (and asked) if libvirt can do a better job - in saving in a cyclic log the QMP commands sent and the response from the guest and dump it in case of a guest crash.</div><div>- Attended a Cockpit hackfest[9] - as we intend to use Cockpit as our UI for RHEVH Next Generation Node, it was great to present our use case and exchange thoughts, ideas and directions. Few bugs were filed during the hackfest per our comments.</div><div>- Attended 'Dockerizing JBoss Applications' presentation[10]. Great work done by the JBoss team to improve and streamline packaging of JBoss into containers. </div><div>- Attended 'Fedora Upstream Testing' presentation[13]. I disscussed with the presentor the possibiliy to run oVirt with Lago[17] in Fedora, in a CI way, by monitoring distgit changes for relevant packages (such as lvm2, device-mapper*, libvirt and others.</div><div>- Attended 'High Performance VMs in OpenStack'[12] - looks like oVirt is already doing a lot of what OpenStack are working to achieve high-performance from KVM!</div><div>- Preached on running Lago with OpenStack, Gluster and Cockpit. At least the first two items look really promising and I'm looking forward to a collaboration in those efforts. I might just try to do the Gluster one myself.</div><div>- Having used the oVirt Live[18] USB DoK image in both FOSDEM and DevConf, I've found several items where we can improve in and filed relevant RFEs for them[15][16].</div><div><br></div><div>- The oVirt team has delivered numerous presentations in the virtualization track[1][2][6] - and the Gluster team has additionally provided more presentations[7][8], which were all well received.</div><div><br></div><div>I'd like to thank Red Hat's OSAS team members Mikey and Brian for once again, just one week after FOSDEM, leading the effort of representing the oVirt project and community in this event.</div><div>Y.</div><div><br></div><div>[1] <a href="https://www.youtube.com/watch?v=cQqJEiK7-Ug" target="_blank">https://www.youtube.com/watch?v=cQqJEiK7-Ug</a> - Smart VM Scheduling - Martin Sivák </div><div>[2] <a href="https://www.youtube.com/watch?v=V1JQtmdleaM" target="_blank">https://www.youtube.com/watch?v=V1JQtmdleaM</a> - Host fencing in oVirt - Fixing the unknown and allowing VMs to be highly available - Martin Peřina</div><div>[3] <a href="https://www.youtube.com/watch?v=XkMIMJKJeTY" target="_blank">https://www.youtube.com/watch?v=XkMIMJKJeTY</a> - in-depth look of virtual machine migration algorithms - Marcelo Tosatti</div><div>[4] <a href="https://www.youtube.com/watch?v=Jx93riUF5_I" target="_blank">https://www.youtube.com/watch?v=Jx93riUF5_I</a> - Qemu Disk I/O: Which performs better, Native or Threads? - Pradeep K Surisetty</div><div>[5] <a href="https://www.youtube.com/watch?v=Dd2AGGMWXQM" target="_blank">https://www.youtube.com/watch?v=Dd2AGGMWXQM</a> - Debugging the Virtualization Layer (libvirt and QEMU) in OpenStack - Kashyap Chamarthy</div><div>[6] <a href="https://www.youtube.com/watch?v=4CbHTAkVDZo" target="_blank">https://www.youtube.com/watch?v=4CbHTAkVDZo</a> - Ceph integration with oVirt using Cinder - Nir Soffer</div><div>[7] <a href="https://www.youtube.com/watch?v=XudYwEWQF7U" target="_blank">https://www.youtube.com/watch?v=XudYwEWQF7U</a> - oVirt and Gluster Hyperconvergence - Ramesh Nachimuthu</div><div>[8] <a href="https://www.youtube.com/watch?v=TczVVCbm8NE" target="_blank">https://www.youtube.com/watch?v=TczVVCbm8NE</a> - Improvements in gluster for virtualization usecase - Prasanna Kumar Kalever</div><div>[9] <a href="https://www.youtube.com/watch?v=TNDe90WSZow" target="_blank">https://www.youtube.com/watch?v=TNDe90WSZow</a> - Cockpit Hackfest - Dominik Perpeet, Marius Vollmer, Peter Volpe, Stef Walter</div><div>[10] <a href="https://www.youtube.com/watch?v=NpyEoFlDzOQ" target="_blank">https://www.youtube.com/watch?v=NpyEoFlDzOQ</a> - Dockerizing JBoss Products - David Becvarik</div><div>[11] <a href="https://www.youtube.com/watch?v=rqavfmPAt7o" target="_blank">https://www.youtube.com/watch?v=rqavfmPAt7o</a> - Avocado and Jenkins: Test Automation and CI - Lukáš Doktor, Yash Mankad</div><div>[12] <a href="https://www.youtube.com/watch?v=9J_sEdlpIlQ" target="_blank">https://www.youtube.com/watch?v=9J_sEdlpIlQ</a> - High performance VMs in OpenStack - Nikola Dipanov</div><div>[13] <a href="https://www.youtube.com/watch?v=15-yXOJuonQ" target="_blank">https://www.youtube.com/watch?v=15-yXOJuonQ</a> - Upstream First Testing - Tim Flink</div><div>[14] <a href="https://www.youtube.com/watch?v=q4gU87wdRtI" target="_blank">https://www.youtube.com/watch?v=q4gU87wdRtI</a> - Growing the ARM server ecosystem - Jim Perrin</div><div>[15] <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1307261" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1307261</a> - [RFE] register .vv files so they'll be opened automatically with remote-viewer</div><div>[16] <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1307262" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1307262</a> - [RFE] Disable power management (display and computer)</div><div>[17] <a href="https://github.com/lago-project/lago" target="_blank">https://github.com/lago-project/lago</a></div></div>
