disable ticketing script prevents console from opeing from web
by Dan Sullivan 25 May '17

25 May '17

We want to disable ticketing on the VNC connections to our VMs. I created a hook script that removes the passwd and passwdValidTo attributes from the XML file and this seems to work OK. The one problem is that I cannot open the console from the web portal. I get a "set ticket" failure. Is there a work around for this? Thanks

terminating sessions
by Fabrice Bacchella 25 May '17

25 May '17

In the UI, I see 73 open sessions, all open by me. In ovirt logs, I see a lot of : 2017-05-03 18:49:31,483+02 INFO [org.ovirt.engine.core.bll.aaa.SessionDataContainer] (DefaultQuartzScheduler3) [dcf02fc4-72c3-4237-8855-d4e474766088] Not removing session 'B/GWJOxyLh3pXQPPitfCk29iiJ3XWMerYdNmOdZyc9ceqD+oAW/hhhZDXCltK+N4yRo9TgunhGR7w7YEELOI5A==', session has running commands for user 'XXXX'. And indeed I can't close those sessions in the UI. I have two questions: Are those sessions accessible using the API ? How to know what running command is waiting ?

Hi everyone, new guy in the mail list
by Odilon Junior 25 May '17

25 May '17

Hi everyone, i've just subscribed to the maling list, I was going to ask one thing about ovirt in the IRC channel but no one was there. I've been using ovirt since 3.1, today we have one enviroment with 1 Ovirt Engine and 3 baremetal that we use for virtualization running the Ovirt 3.6.3. We have 3 NFS share from our colocation provider that are used as Storage. Our collocation will be rolling one emergency maintenance to upgrade the firmware on the routers that provides our Private Network, the NFS service run on this Private Network,the downtime should be no more than 3 minutes. I'm concerned, what is the best way to approach this, should we shutdown all the VMs and the hypervisor? Or we can just let the Ovirt handle this? The communication between the Ovirts and the Engine are from another network that will not be affected.

ovirt-node-ng & gluster installation question

--_000_1a4617a5197e4f46a3a96486ec87a254DENU01MS0077phoenixloc_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable I'm trying to install latest oVirt release on a cluster lab. I have 6 servers and I need to use gluster from hyperconverged hosted engin= e lab, all of them have volumes for gluster storage, apart OS disks. Servers are installed with ovirt-node-ng-installer-ovirt-4.1-pre-2017051210= iso image. After installation, full update. I'm try to follow the guide in : http://www.ovirt.org/blog/2017/04/up-and-r= unning-with-ovirt-4-1-and-gluster-storage/ In this guide, I can seen in the host selection, the possibility to add mor= e than three hosts to the cluster. In current cockpit version, I can't see this. These are cockpit components, installed in all six servers: cockpit-ws-140-1.el7.centos.x86_64 cockpit-system-140-1.el7.centos.noarch cockpit-140-1.el7.centos.x86_64 cockpit-dashboard-140-1.el7.centos.x86_64 cockpit-storaged-140-1.el7.centos.noarch cockpit-ovirt-dashboard-0.10.7-0.0.18.el7.centos.noarch cockpit-bridge-140-1.el7.centos.x86_64 Two questions: Must I proceed with only three servers and only after add the remainder thr= ee to the cluster, to have distributed&replicated gluster solution or I mus= t change something in the first installation phase, to add all six servers = from the beginning ? In the second cockpit screen there aren't default repo/packages, must I lea= ve it blank ? (servers are already updated). Thanks in advance for any hints.

migration of a VM: fails
by cmc 24 May '17

Hi, Just trying to place in maintenance mode for a version upgrade, and one VM fails to migrate. The other 20-odd move over successfully. In /var/log/libvirt/qemu/, the VM's log on the source reports: 2017-05-16 09:48:06.339+0000: initiating migration 2017-05-16T09:52:25.498932Z qemu-kvm: socket_writev_buffer: Got err=32 for (131328/18446744073709551615) 2017-05-16 09:52:47.311+0000: initiating migration 2017-05-16T09:57:06.755402Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 09:57:55.109+0000: initiating migration 2017-05-16T10:02:14.143221Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 10:02:59.497+0000: initiating migration 2017-05-16T10:07:18.542872Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 10:08:03.896+0000: initiating migration 2017-05-16T10:12:23.206731Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 10:13:08.941+0000: initiating migration 2017-05-16T10:17:27.861843Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 10:18:13.690+0000: initiating migration 2017-05-16T10:22:32.929689Z qemu-kvm: socket_writev_buffer: Got err=32 for (69803/18446744073709551615) 2017-05-16 10:23:19.846+0000: initiating migration 2017-05-16T10:27:39.175724Z qemu-kvm: socket_writev_buffer: Got err=32 for (69776/18446744073709551615) 2017-05-16 10:28:25.141+0000: initiating migration 2017-05-16T10:28:35.620070Z qemu-kvm: socket_writev_buffer: Got err=32 for (65753/18446744073709551615) 2017-05-16 10:29:10.678+0000: initiating migration 2017-05-16T10:33:29.718527Z qemu-kvm: socket_writev_buffer: Got err=32 for (53477/18446744073709551615) 2017-05-16 10:38:35.517+0000: initiating migration On the destination host, it reports: 2017-05-16T10:33:29.598425Z qemu-kvm: Unknown combination of migration flags: 0 2017-05-16T10:33:29.599524Z qemu-kvm: error while loading state section id 2(ram) 2017-05-16T10:33:29.601978Z qemu-kvm: load of migration failed: Invalid argument 2017-05-16 10:33:29.808+0000: shutting down In the engine log: 2017-05-16 11:57:28,675+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (DefaultQuartzScheduler5) [f8aa18b3-97b9-48e2-a681-cf3aaed330a5] VM '4921c5f5-7748-47eb-a90c-8e9ecbd91bcf'(pete_win7) was unexpectedly detected as 'MigratingTo' on VDS '424e6317-ad68-459b-bf88-7292e26710ae'(kvm-ldn-02) (expected on 'e050c27f-8709-404c-b03e-59c0167a824b') It stays in 'preparing for maintenance mode' on the GUI for the host, and reports errors on the status pane below, but then it reports that the host has successfully been put into maintenance mode, even though the VM is still showing as in migration. After more time has elapsed, it reports a failure again, and then eventually the host will again report it is in maintenance mode, and so on. When I hit 'cancel migration' it reports that the migration has been successfully cancelled in the status pane at the bottom, but then shows it still in migration in the upper window. When I select the VM itself, it reports it is "Migrating From: 99%". If I cancel the migration here, it actually does cancel the migration properly. The VM itself is up and running ok. Version of oVirt is 4.1.0.4-1.el7 Thanks in advance for any help. Please let me know if you need any full logs. Regards, Cam

Rename already defined logical network
by Luca 'remix_tj' Lorenzetto 23 May '17

23 May '17

Hello, i'm developing a migration tool from VMware to oVirt. I'm creating automatically a set of logical networks through API, starting from the list of existing networks that are in VMware. In some cases the name that is set by the script isn't so much pretty (mostly because source name is horrible). At the end of the migration, i'd like to change the name of some of this networks to give them a prettier name. Is there any way to rename logical networks after their assignment to physical devices? I have running VMs on that network, so deleting and adding it back its not an option.

Info on host not responding event and related actions
by Gianluca Cecchi 23 May '17

23 May '17

Hello, I have an oVirt 4.1.1 environment with: - engine is a vSphere CentOS 7.3 VM with its nic on say vlan1 - 2 x hosts (CentOS 7.3) with their ovirtmgmt lan on a bonding (active-backup) on say vlan2 network architecture layout is to put hypervisors and mgmt servers in different vlans Today we had these 4 events below shown in our engine, with root cause apparently a maintenance network routing activity (it should have been transparent, network guys told..., but this is another story ;-) No alert message inside VMs 4) May 23, 2017 1:43:58 PM Host ov300 power management was verified successfully. 3) May 23, 2017 1:43:58 PM Status of host ov300 was set to Up. 2) May 23, 2017 1:43:55 PM Executing power management status on Host ov300 using Proxy Host ov301 and Fence Agent ipmilan:10.10.193.103. 1) May 23, 2017 1:43:37 PM Host ov300 is not responding. It will stay in Connecting state for a grace period of 61 seconds and after that an attempt to fence the host will be issued. Can anyone tell exactly the meaning of the different lines? Is the 1) detected because the engine, from only a network point of view, was not able to ping/reach the hostname of the host ov300, or the "not responding" is any particular specific check? Is the "61 seconds" delay tunable? Is 2) an additional check to verify status of ov300? In case of failure of test in 2) would the fencing have been immediate or the delay described in 1) would have taken place? Are 3) and 4) messages independent from the engine being able to reach ov300 or the 61 seconds delay would have been true anyway? Hope I have explained my doubts related to events that could determine a potential fencing of an active node with its running VMs... with the "only" temporary problem of connectivity between the engine and one of the nodes... Thanks in advance, Gianluca
