The export / import can only be done when VM down? I last used oVirt at 3.6 so looking forward to the new features!

Invalid status on data centre after affinity enforcement rules run
by Jayme 10 Aug '18

10 Aug '18

I have a newly built three node HCI glusterFS cluster (deployed with cockpit) running ovirt 4.2.5 I'm noticing that a few times a day I'm seeing the following event log: Invalid status on Data Center Default. Setting status to Non Responsive. In every single case it happens about 10 seconds after the previous event log: Affinity Rules Enforcement Manager started. Is it normal to see this temporary non responsive state of the default data center? I've also noticed something a bit odd with my hostedEngine. It seems to be restarting on its own and correlates to around the time the above warnings are in the event log. My hosted engine says it has an uptime of 10 minutes right now but I haven't touched it or rebooted it in several days. The events for hostedEngine specifically don't show any logs or problems for several weeks. Question is, why is the default data center intermittently going non-responsive and why is my hostedEngine seemingly restarting itself?

Drive letter / scsi id not consistent
by Nathan March 09 Aug '18

09 Aug '18

Hi, Managing disks in the ovirt gui seems completely error prone since the GUI ordering does not seem to be used in any practical way. The scsi ID's are not exposed via the GUI either, so if you have 2 drives of the same size on NFS there's no way to identify which is which without resorting to dumping the xml. I see in the xml that the target dev is correct and matches up with the GUI's drive order, but the scsi unit seems to be generated based on the order of last activated: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='scsi0-0-0-3'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> After deactivating the other 2 disks and rebooting the machine, sda has now become unit 3: <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> and then I shutdown, activated the extra 2 drives, booted it back up but now I'm still on unit 3: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='ua-0b020d24-3dea-4be7-931a-9c25ccfeec48'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> I managed to get things into the correct state by shutting down the VM, deactivating all the disks, then activating them in the order I want them to show up. This sets the correct order of unit 0 for sda, unit 1 for sdb, unit 2 for sdc. Is there some way to make ovirt treat this in a sane way and always expose the scsi devices in the same order as the GUI (and the "target dev" field)? Cheers! Nathan

Live Migration via NFS
by Douglas Duckworth 09 Aug '18

09 Aug '18

Hi I haven't used oVirt in several years so wanted to ask how live migration may have changed. Can NFS facilitate live migration in cluster of two hosts each which have NFS mounted? The hosts would have local attached storage which would be the original location of VMs.

Hello, I have 24 HP DL360 G7 all with 64G RAM and 1TB SAS disks. What I want to archive is to use all the nodes with ovirt (one will be for the controller + iso domain) and use GluterFS in the same nodes for the storage domain. Idk if anyone tried it before, but I want it to replace my actual "standalone" production hypervisors schema. Thanks in advance

Failed to hot-plug disk
by Punaatua PK 08 Aug '18

08 Aug '18

Hello, I have a problem when i tried to hotplug a disk to a VM. Here is the situation. We use a VM (let's call this backupVM) which is responsible of doing our VM backup by : - Making a snapshot of the VM we want to backup - Attach the snapshot disk - Make the copy using DD - Unplug the snapshot disk and then delete snapshot. For some reason that i don't know, for certain VM, the backupVM cannot hot plug the snapshot disk. I'm using ovirt 4.2.4 Here is what is see in engine.log 2018-08-04 19:52:30,496-10 ERROR [org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand] (default task-61) [361eca85-ca85-4e23-b292-cd8303a1a86d] Command 'org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand' failed: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to HotPlugDiskVDS, error = internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock, code = 45 (Failed with error FailedToPlugDisk and code 45) Here is the vdsm.log 2018-08-04 19:51:38,512-1000 INFO (jsonrpc/5) [virt.vm] (vmId='78ef239f-3cb3-4eef-921f-f989724009ef') Hotplug disk xml: <?xml version='1.0' encoding='utf-8'?> <disk address="" device="disk" snapshot="no" type="file"> <source file="/var/lib/vdsm/transient/225ec856-d661-4374-bb7d-8ea7168fe5f2-b641bb09-325a-4932-a9af-32c907e4a381.D52Nkj" /> <target bus="virtio" dev="vdg" /> <serial>c312a0c3-8c58-472f-99ad-cfbabb42337d</serial> <driver cache="writethrough" error_policy="stop" io="threads" name="qemu" type="qcow2" /> </disk> (vm:3859) 2018-08-04 19:51:38,672-1000 ERROR (jsonrpc/5) [virt.vm] (vmId='78ef239f-3cb3-4eef-921f-f989724009ef') Hotplug failed (vm:3867) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 3865, in hotplugDisk self._dom.attachDevice(driveXml) File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 98, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 130, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 92, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 570, in attachDevice if ret == -1: raise libvirtError ('virDomainAttachDevice() failed', dom=self) libvirtError: internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock here is libvirtd log in /var/log/messages libvirtd: 2018-08-05 05:51:38.637+0000: 4967: error : qemuMonitorJSONCheckError:389 : internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock Do you guys have any idea of what going on ?

VirtIO in new upgraded 4.2.5 for FreeBSD is very poor (could not use)
by Paul.LKW 08 Aug '18

08 Aug '18

Dear All: I just upgraded my oVIrt-4.2.4 to 4.2.5 and nightmare begin, FreeBSD VMs hangs once the VM's VirtIO harddisk is some loading (eg. extracting a big tar ball, portsnap extract, etc.), I tried to create a VMs using back the IDE do not has any problem but got slow IO performance once using VirtIO it will hang as it like. I also tried to create another VMs with VirtIO-SCSI it seems the hang problem no occur but I got the oVirt-Host loading over 40 when VM harddisk have some little job, so conclusion is if you guys will using FreeBSD as guest please do not upgrade at the moment. In fact I feel every time the new version always have problem and causing user to nightmare. BR, Paul.LKW

Space in entity names (VM and Network) in oVirt
by Hari Prasanth Loganathan 08 Aug '18

08 Aug '18

Hi Team, I have VM's and Network's in oVirt with space in the name. How can I perform an exact search for the following name *Name1*: Aug X X *Name2*: Aug X X X 1) I try to search with space in the name, It is not working. https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug X X It is not returning any result. 2) I try to search with encoded value for space in the name, It is not working. (encoded value for space is %20) https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug%20X%20X 3) I try to search like below with '*' for space and end up getting both the values in response, https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug*X so what is the correct way to search the name with space ?

Re: Update to 4.2.5, Cant start VMs

Indeed the Storage domains are via NFS served by Windows Server 2016. the workaround says "use NFSV3", I'm afraid this will break my existing installation. For now, all my VMs are running on one host that is still on 4.2.0.

Update to 4.2.5, Cant start VMs
by Vincent Royer 07 Aug '18

07 Aug '18

I updated the engine, and one of my nodes to 4.2.5. I'm attempting to re-start the VMs that were pinned to it, and migrate another VM to it so that I can update my other node. When I try to start the VMs that were pinned to the host, I get: VM Tuning3 is down with error. Exit message: XML error: Multiple 'scsi' > controllers with index '0'. To fix this I tried to detach the disk and re-attach it, no luck. When I try to migrate a running VM to this host, I get: Host Letty has network interface which exceeded the defined threshold [95%] > (bond0: transmit rate[0%], receive rate [97%]) The host I'm migrating FROM gets a similar error, and the VM does not migrate. I tried the different migration policies without any luck. I did successfully migrate the Hosted Engine to the new host, no errors. Thanks for any advice! Vincent
