FOSDEM16 Virt & IaaS Devroom CFP Extension, Speaker Mentoring, CoC
by Mikey Ariel 23 Nov '15

23 Nov '15

The CFP for the Virtualization & IaaS devroom at FOSDEM 2016 is in full swing, and we'd like to share a few updates with you: ------------------------- Speaker Mentoring Program ------------------------- As a part of the rising efforts to grow our communities and encourage a diverse and inclusive conference ecosystem, we're happy to announce that we'll be offering mentoring for newcomer speakers. Our mentors can help you with tasks such as reviewing your abstract, reviewing your presentation outline or slides, or practicing your talk with you. You may apply to the mentoring program as a newcomer speaker if you: * Never presented before or * Presented only lightning talks or * Presented full-length talks at small meetups (<50 ppl) Submission guidelines: * Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. * The number of newcomer session slots is limited, so we will probably not be able to accept all applications. * You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email iaas-virt-devroom at lists.fosdem.org and we will try to help you. How to apply: * Follow the same procedure to submit an abstract in Pentabarf as standard sessions. Instructions can be found in our original CFP announcement: http://community.redhat.com/blog/2015/10/call-for-proposals-fosdem16-virtua… * In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Call for mentors! Interested in mentoring newcomer speakers? We'd love to have your help! Please email iaas-virt-devroom at lists.fosdem.org with a short speaker bio and any specific fields of expertise (for example, KVM, OpenStack, storage, etc) so that we can match you with a newcomer speaker from a similar field. Estimated time investment can be as low as a 5-10 hours in total, usually distributed weekly or bi-weekly. Never mentored a newcomer speaker but interested to try? Our mentoring program coordinator will be happy to answer your questions and give you tips on how to optimize the mentoring process. Email us and we'll be happy to answer your questions! ------------------------- CFP Deadline Extension ------------------------- To help accommodate the newcomer speaker proposals, we have decided to extend the deadline for submitting proposals by one week. The new deadline is **TUESDAY, DECEMBER 8 @ midnight CET**. ------------------------- Code of Conduct ------------------------- Following the release of the updated code of conduct for FOSDEM[1], we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email iaas-virt-devroom at lists.fosdem.org and we will do our best to help you out.

Cannot setup Networks. The address of the network 'NFS' cannot be modified
by Ihor Piddubnyak 23 Nov '15

Trying to change IP for VLAN interface attached to hypervisor, getting vhi2: Cannot setup Networks. The address of the network 'NFS' cannot be modified without reinstalling the host, since this address was used to create the host's certification. Host reinstall does not help. Any clue how to do it? -- Ihor Piddubnyak <ip(a)surftown.com> surftown a/s

3.6: GlusterFS data domain failover?
by Wee Sritippho 23 Nov '15

23 Nov '15

------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=UTF-8 Hi, My POC environment have 2 hosts - host A and host B, both are CentOS7. Installed oVirt 3.6 self-hosted engine. I manually created a 2-brick GlusterFS volume using both hosts and added it to my datacenter. I tried shutting down host A. The hosted-engine restarted in host B within 3 minutes, which is very cool. However, the GlusterFS data domain, which I set both 'Use Host' and 'Path' to the host A, is down along with it. Here comes my questions: 1. How can I enable failover GlusterFS data domain? 2. How can I reverse back to the state before adding the data domain? The data domain is super persistent - I can't edit or delete it. I put it to maintenance mode but still unable to detach or destroy it because it requires me to remove the datacenter first. I tried but can't remove the datacenter either. 3. Why can't I add another GlusterFS data domain? When I choose 'GlusterFS' as my 'Storage Type' every text field become grayed-out. 4. When host A restarted again, I notice that 'Use Host' was changed from host A to host B instead. Is this an expected behavior? Regards, Wee Sritippho P.S: Please excuse my poor English. ------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 8bit Hi, My POC environment have 2 hosts - host A and host B, both are CentOS7.

report option gone missing
by Rik Theys 23 Nov '15

23 Nov '15

Hi, At some point I had the oVirt reporting configured on my engine and it worked. I had a "reports" option in the menu and could generate reports for various resources. At some point I've noticed that the "reports" option was no longer there but did not have time to investigate. I believe it happened when I migrated the engine host from CentOS 6 to 7 using engine-backup and restore. How can I debug this? In the ovirt-engine-dwh log I used to see the following error: Exception in component tJDBCRollback_4 org.postgresql.util.PSQLException: FATAL: terminating connection due to administrator command at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2157) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1886) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:255) at org.postgresql.jdbc2.AbstractJdbc2Connection.executeTransactionCommand(AbstractJdbc2Connection.java:793) at org.postgresql.jdbc2.AbstractJdbc2Connection.rollback(AbstractJdbc2Connection.java:846) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_4Process(HistoryETL.java:2079) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_3Process(HistoryETL.java:1997) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_2Process(HistoryETL.java:1882) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_1Process(HistoryETL.java:1767) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tPostjob_1Process(HistoryETL.java:1647) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.runJobInTOS(HistoryETL.java:10785) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.main(HistoryETL.java:10277) 2015-11-19 15:42:02|rza8ri|rza8ri|rza8ri|OVIRT_ENGINE_DWH|HistoryETL|Default|6|Java Exception|tJDBCRollback_4|org.postgresql.util.PSQLException:FATAL: term But after rebooting the engine host it now only lists 'Service Started'. The ovirt-engine-reportsd is also running. Which of these two processes (reportsd vs dwhd) is generating the reports (and showing it in the engine admin interface)?
