vdsm losing connection to libvirt
by Chris Adams 17 Dec '14

17 Dec '14

I have a oVirt setup that has three nodes, all running CentOS 7, with a hosted engine running CentOS 6. Two of the nodes (node8 and node9) are configured for hosted engine, and the third (node2) is just a "regular" node (as you might guess from the names, more nodes are coming as I migrate VMs to oVirt). On one node, node8, vdsm periodically loses its connection to libvirt, which causes vdsm to restart. There doesn't appear to be any trigger that I can see (not time of day, load, etc. related). The engine VM is up and running on node8 (don't know if that has anything to do with it). I get some entries in /var/log/messages repeated continuously; the "ovirt-ha-broker: sending ioctl 5401 to a partition" I mentioned before, and the following: Dec 15 20:56:23 node8 journal: User record for user '107' was not found: No such file or directory Dec 15 20:56:23 node8 journal: Group record for user '107' was not found: No such file or directory I don't think those have any relevance (don't know where they come from); filtering those out, I see: Dec 15 20:56:33 node8 journal: End of file while reading data: Input/output error Dec 15 20:56:33 node8 journal: Tried to close invalid fd 0 Dec 15 20:56:38 node8 journal: vdsm root WARNING connection to libvirt broken. ecode: 1 edom: 7 Dec 15 20:56:38 node8 journal: vdsm root CRITICAL taking calling process down.

1. FQDN for vm creating with hosted-engine (Yue, Cong)
by Nikolai Sednev 17 Dec '14

17 Dec '14

------=_Part_11273251_1557423152.1418807793774 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit FQDN or fully qualified domain name means that you have to reserve in your DNS a name corresponding to IP received by HE VM from DHCP. IP address should be reserved for the VM at DHCP. I advise not to use manual IP to FQDN at your host, as this will lead to many confusions, especially when you'll have more than a single host machine, but you always can configure at your /etc/hosts file the FQDN corresponding to IP address given to HE VM. Thanks in advance.

We just bought a new server that supports the Conroe CPU model, and I am trying to install Server 2012 R2 without luck. I keep getting error code 0x000000C4. The problem is while Windows is still to load into its pre-installation environment it cashes and then immediately resets. This is a continuous loop. I have found a way to install Server 2012 R2. Move the cluster away from the Conroe Family (in my case Penryn). Thanks for all you do. -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Release management for 3.6.0 [1] has been updated following the new release process[2]. ACTION: Feature proposed for 3.6.0 must now be collected in the 3.6 Google doc [3] and reviewed by maintainers. Finished the review process, the remaining key milestones for this release will be scheduled. For reference, external project schedules we're tracking are: Fedora 21: 2014-12-09 (RELEASED) Fedora 22: no earlier than 2015-05-19 Foreman 1.8.0: 2015-03-01 GlusterFS 3.7: 2015-04-29 OpenStack Kilo: 2015-04-30 QEMU 2.1.3: 2014-12-29 QEMU 2.2.0: 2014-12-09 (RELEASED) The tracker bug for 3.6.0 [4] currently shows no blockers. There are 461 bugs [5] targeted to 3.6.0. Excluding node and documentation bugs we have 438 bugs [6] targeted to 3.6.0.

[QE][ACTION REQUIRED] oVirt 3.5.1 RC status
by Sandro Bonazzola 17 Dec '14

17 Dec '14

Hi, according to the new oVirt 3.5.1 schedule, we're going to start composing oVirt 3.5.1 RC on *2015-01-07 08:00 UTC* from 3.5 branch. The new GA release date is now targeted to 2015-01-14. VDSM team decided to release a new vdsm package as async release for 3.5.0. Due to issues with Fedora Koji Build System packages are not yet ready to be released. ACTION: VDSM team to follow up when the packages will be ready to be released. The bug tracker [1] shows 1 open blocker: Bug ID Whiteboard Status Summary 1160846 sla NEW Can't add disk to VM without specifying disk profile when the storage domain has more than one disk profile In order to stabilize the release a new branch ovirt-engine-3.5.1 will be created from the same git hash used for composing the RC. - ACTION: assignee please provide ETA on above blocker Maintainers: - Please be sure that 3.5 snapshot allow to create VMs - Please be sure that no pending patches are going to block the release - If any patch must block the RC release please raise the issue as soon as possible. There are still 62 bugs [2] targeted to 3.5.1. Excluding node and documentation bugs we still have 41 bugs [3] targeted to 3.5.1. Maintainers / Assignee: - Please add the bugs to the tracker if you think that 3.5.1 should not be released without them fixed. - ACTION: Please update the target to 3.5.2 or later for bugs that won't be in 3.5.1: it will ease gathering the blocking bugs for next releases. - ACTION: Please fill release notes, the page has been created here [4] Community: - If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [5] [1] http://bugzilla.redhat.com/1155170 [2] http://goo.gl/7G0PDV [3] http://goo.gl/6gUbVr [4] http://www.ovirt.org/OVirt_3.5.1_Release_Notes [5] http://www.ovirt.org/Testing/oVirt_3.5.1_Testing Thanks, -- Sandro Bonazzola Better technology.

Hi, I want to know more about the Ovirt engine and host node heartbeat settings and interval....that means how and when the engine node consider the host node as dead or shoot the command to fence it for reboot.... Is there any way to modify those interval and settings to prevent the false-positive etc... Thanks, Punit

Only the wizard to 'configure local storage' requires this at it performs create DC, create cluster, move host to new cluster, add storage domain.
