IP address doesn't appear in the host network interfaces tab
by Nathanaël Blanchet 25 Nov '16

25 Nov '16

Hi all, I try to change my migration network from one to an other. To do such a thing I assigned an IP on the new vlan fo r each of my hosts by dhcp.but when changing the migration network at the cluster level, engine complains that my host doesn't have IP. I tried the "Sync all networks tab" to refresh, but nothing happens. Howver IP in the vlan do exist on the host. The only workaround to do this is to restart vdsmd and then, IP appear and I can go further. Can it be considered as a bug? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

used bandwidth when live migrating
by Nathanaël Blanchet 25 Nov '16

25 Nov '16

Hi all, We use in production a dedicated 10G vlan link for live migration. In the cluster option tab I put the migration bandwidth limit to 10000 Mbps. Everything work as expected and now 25 vms on a host migrate in a few seconds (excatly 13), but I'm not able to measure the real consumed bandwidth. I want to evaluate such a thing beacuse my goal is to dedicate a vlan for gluster ont the same 10G nic, and I don't want an overload issue with gluster when vms migrations happen. So my questions are : how does live migration work? Is it a RAM to RAM transport between two hosts? Are migration bandwidth limited by I/O disk anywhere or by the nic capabilities? Could 10Gbps be fully used for such staff? What would you advice to make work gluster and migration on the same nic (QoS?) Thank you for help. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

4.0.5 create vm from template on cinder/ceph backed storage
by Jordan Conway 25 Nov '16

25 Nov '16

I've got a problem where since upgrading to 4.0.5 I am still unable to create a vm from a template. The issue now is that it seems to be stuck in a loop trying to and failing to create the vm, which is making my logs explode with the following https://paste.fedoraproject.org/489161/14799981/ And in the engine UI "Failed to complete VM fromtemplate-1 creation." thousands of times. The issue started I believe with this sql error https://paste.fedoraproject.org/489183/00010131/ Any insight on how I can stop the persistent error would be appreciated, as it is also preventng me from running engine-setup due to running jobs, even though vdsclient shows nothing. vdsClient -s 0 getAllTasksStatuses {'status': {'message': 'OK', 'code': 0}, 'allTasksStatus': {}} Thank you, Jordan Conway

vm.conf on one of the node is missing
by knarra 25 Nov '16

25 Nov '16

Hi, I have three nodes with glusterfs as storage domain. For some reason i see that vm.conf from /var/run/ovirt-hosted-engine-ha is missing and due to this on one of my host i see that Hosted Engine HA : Not Active. Once i copy the file from some other node and restart ovirt-ha-broker and ovirt-ha-agent services everything works fine. But then this happens again. Can some please help me identify why this happens. Below is the log i see in ovirt-ha-agent.logs. https://paste.fedoraproject.org/489120/79990345/ Thanks kasturi

hi I apologize if I missed it reading release(repo) note. What are users supposed to do with EPEL repo? I'm asking for hit this: --> Package python-perf.x86_64 0:4.8.7-1.el7.elrepo will be an update --> Finished Dependency Resolution Error: Package: nfs-ganesha-gluster-2.3.0-1.el7.x86_64 (@ovirt-4.0-centos-gluster37) Requires: nfs-ganesha = 2.3.0-1.el7 Removing: nfs-ganesha-2.3.0-1.el7.x86_64 (@ovirt-4.0-centos-gluster37) nfs-ganesha = 2.3.0-1.el7 Updated By: nfs-ganesha-2.3.2-1.el7.x86_64 (epel) nfs-ganesha = 2.3.2-1.el7 and I also wander if there might be more? regards.

ovirt 4.0.6 - live disk migration fails
by Maton, Brett 24 Nov '16

24 Nov '16

If I try to migrate a disk of a running VM to another storage domain it fails with the following message: Operation Cancelled Error while executing action: User is not logged in. Migrating disks of stopped VM's continues to work. Probably a bug ?

Storage questions
by Oscar Segarra 24 Nov '16

24 Nov '16

Hi, I'm planning to deploy a scalable VDI infraestructure where each phisical host can run over 100 VDIs and I'd like to deploy 10 physical hosts (1000 VDIs). In order to avoid performance problems (replicating 1000VDIs changes over gluster network I think can provoque performance problems) I have thought to use local storage for VDI assuming that VDIs cannot be migrated between phisical hosts. ¿Is my worry founded in terms of performance? ¿Is it possible to utilize local SSD storage for VDIs? I'd like to configure a gluster volume for backup on rotational disks (tiered+replica 2+ stripe=2) just to provide HA if a physical host fails. ¿Is it possible to use rsync for backing up VDIs? If not ¿How can I sync/backup the VDIs running on local storage on the gluster shared storage? If a physical host fails ¿How can I start the latest backup of the VDI on the shared gluster? Thanks a lot
