Strange migration issue
by Demeter Tibor 09 Dec '18

09 Dec '18

Dear All, I've using ovirt from 3.4 and we have a strange, rarely problem with live migrations. - In most of case impossible to do a live migrate of VMs that have a lot of memory (16 gigs and more up to 40 GB) . - Those are need to try and try until the migration will be successful - impossible to understand why does working in a case and doesn't in another - it is happening always if there bigger load on vms, but only on big memory VM-s - The small VMs (2-4-8 gigs) can migrate without problems - In very rarely cases possible to migrate on first try. - We using the memory ballooning function on all of VMs. We using dedicated migration network with separated vlans, but on same physical lan (1gbe) with ovirtmgmt. At this moment, we don't use QoS for dedicate bandwidth. What can I do ? Thanks in advance, Regards, Tibor

Removing stale unused disks from Ovirt Storage domains?
by Jacob Green 07 Dec '18

07 Dec '18

Hello, after migrating our Fiber Channel to a new Ovirt 4.2 environment, we over the years and through experimenting and mistakes have ended up with some stale LVM's/disks on our fibre channel storage that Ovirt no longer is able to manage correctly or is unaware of. I am looking for a reliable to way to do a few different things. The first is figuring out precisely what LVM ids belong to a VM and is being used by that VM. The second is figuring out if a LVM I have found on the Storage domain is being used at all by any VM or if ovirt is even aware of it. I have fumbled around a bit. And using a combination of the following I have been able to figure out some of them. But now I am finding information that does not match or may not be correct or I am interpreting the data wrong. Anyway this is a big deal, because we want to remove the stale unused LVMs and it would obviously be disastrous if I deleted the wrong LVM from the FC. So I know its not recommend but since I am not actually telling vdsm-client to do anything other than get information I figure its harmless. So here is what I have found so far. *vdsm-client Host getVMFullList vmname=<VM_NAME_HERE> | grep volumeID* *lvs | grep <noted volumeID here>* With the above I have had some success verifying what LVMs a device is using. However now I am having trouble figuring out a particular windows server VMs LVM id's. what I want to know is there a better way? Also two more things. You could call these feature requests, however it would be nice if there was a way to see all the unused LVMs on a storage domain that are not Tied to a VM. And it would also be nice to be able to remove un-imported VMs that reside on a storage domain without importing them. Anyway trying to get rid of un-imported vms and getting rid of unused LVMs has been a chore. I wish there was an easier way. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

VM ramdomly unresponsive
by fsoyer 07 Dec '18

07 Dec '18

Hi all, I continue to try to understand my problem between (I suppose) oVirt anf Gluster. After my recents posts titled 'VMs unexpectidly restarted' that did not provide solution nor search idea, I submit to you another (related ?) problem. Parallely with the problem of VMs down (that did not reproduce since Oct 16), I have ramdomly some events in the GUI saying "VM xxxxx is not responding." For example, VM "patjoub1" on 2018-11-11 14:34. Never the same hour, not all the days, often this VM patjoub1 but not always : I had it on two others. All VMs disks are on a volume DATA02 (with leases on the same volume). Searching in engine.log, I found : 2018-11-11 14:34:32,953+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (EE-ManagedThreadFactory-engineScheduled-Thread-28) [] VM '6116fb07-096b-4c7e-97fe-01ecc9a6bd9b'(patjoub1) moved from 'Up' --> 'NotResponding' 2018-11-11 14:34:33,116+01 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (EE-ManagedThreadFactory-engineScheduled-Thread-1) [] Invalid or unknown guest architecture type '' received from guest agent 2018-11-11 14:34:33,176+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-28) [] EVENT_ID: VM_NOT_RESPONDING(126), VM patjoub1 is not responding. ... ... 2018-11-11 14:34:48,278+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (EE-ManagedThreadFactory-engineScheduled-Thread-48) [] VM '6116fb07-096b-4c7e-97fe-01ecc9a6bd9b'(patjoub1) moved from 'NotResponding' --> 'Up'So it becomes up 15s after, and the VM (and the monitoring) see no downtime. At this time, I see in vdsm.log of the nodes : 2018-11-11 14:33:49,450+0100 ERROR (check/loop) [storage.Monitor] Error checking path /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata (monitor:498) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 496, in _pathChecked delay = result.delay() File "/usr/lib/python2.7/site-packages/vdsm/storage/check.py", line 391, in delay raise exception.MiscFileReadException(self.path, self.rc, self.err) MiscFileReadException: Internal file read failure: (u'/rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata', 1, 'Read timeout') 2018-11-11 14:33:49,450+0100 INFO (check/loop) [storage.Monitor] Domain ffc53fd8-c5d1-4070-ae51-2e91835cd937 became INVALID (monitor:469) 2018-11-11 14:33:59,451+0100 WARN (check/loop) [storage.check] Checker u'/rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata' is blocked for 20.00 seconds (check:282) 2018-11-11 14:34:09,480+0100 INFO (event/37) [storage.StoragePool] Linking /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937 to /rhev/data-center/6efda7f8-b62f-11e8-9d16-00163e263d21/ffc53fd8-c5d1-4070-ae51-2e91835cd937 (sp:1230)OK : so, DATA02 marked as blocked for 20s ? I definitly have a problem with gluster ? I'll inevitably find the reason in the gluster logs ? Uh : not at all. Please see gluster logs here : https://seafile.systea.fr/d/65df86cca9d34061a1e4/ Unfortunatly I discovered this morning that I have not the sanlock.log for this date. I don't understand why, the log rotate seems OK with "rotate 3", but I have no backups files :(. But, luck in bad luck, the same event occurs this morning ! Same VM patjoub1, 2018-11-13 08:01:37. So I have added the sanlock.log for today, maybe it can help. IMPORTANT NOTE : don't forget that Gluster log with on hour shift. For this event at 14:34, search at 13h34 in gluster logs. I recall my configuration : Gluster 3.12.13 oVirt 4.2.3 3 nodes where the third is arbiter (volumes in replica 2) The nodes are never overloaded (CPU average 5%, no peak detected at the time of the event, mem 128G used at 15% (only 10 VMs on this cluster)).

If you have it you can connect the appropriate storage domain using vdsm-client, and then start the VM using that libvirt definition. again, it’s not very easy to do. In all other cases it would have to be generated by the engine again as the OVF_STORE OVF backup is an OVF and you need libvirt’s XML so you would have to convert it first anyway, so again nothing simple to do. In disaster recovery scenrio you can just take the whole storage domain and import it into the new clean engine installation and you’ll get all the VMs it depends what you really want to do Thanks, michal > > вт, 29 мая 2018 г. в 18:53, Michal Skrivanek <michal.skrivanek(a)redhat.com <mailto:michal.skrivanek@redhat.com>>: > > > > On 29 May 2018, at 16:08, David David <dd432690(a)gmail.com <mailto:dd432690@gmail.com>> wrote: > > > > hi. > > > > How to start VM directly in hypervisor? ovirt-engine was crashed. > > that is not supported yet > > > > > VM's id is known. > > > > vdsclient VM, hasn't argumets for starting vm. > > it does, but you need to connect storage and then supply the whole VM configuration which is not simple to do. > > > > > Thanks. > > _______________________________________________ > > Users mailing list -- users(a)ovirt.org <mailto:users@ovirt.org> > > To unsubscribe send an email to users-leave(a)ovirt.org <mailto:users-leave@ovirt.org> > > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ <https://www.ovirt.org/site/privacy-policy/> > > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ <https://www.ovirt.org/community/about/community-guidelines/> > > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/SDTALWD2CHOEE… <https://lists.ovirt.org/archives/list/users@ovirt.org/message/SDTALWD2CHOEE…> >

Cloud-init reset network configuration to default dhcp after reboot and regular run
by Mike Lykov 06 Dec '18

06 Dec '18

Hi All! I'm trying to configure network in VMs created from template, and see strange behaviour from cloud-init. cloud-init installed and enabled in template. ver cloud-init-0.7.9-24.el7.centos.1.x86_64 guest Centos 7.5 ovirt 4.2.7 from ovirt-releases-42-pre repo 1. I use "run once" with initial run - use cloud-init - networks in-guest net iface : eth0 add new - static enter address, mask, gw ipv6 none Run (once) and cloud-init configure ifcfg-eth0 for that address (successfully). 2. I shutdown that VM and use "Run" (regular) without "use cloud init" in VM properties, awaiting that above configurations are saved (and booted with it). But because "use cloud init" not checked, and cloud-init service enabled, it start, cannot find datasource and drop configuration to default (dhcp). In cloud-init.log 2018-11-20 13:53:24,153 - util.py[WARNING]: No instance datasource found! Likely bad things to come! 2018-11-20 13:53:24,153 - util.py[DEBUG]: No instance datasource found!

Additional routes on Interface
by Sandro Emma 06 Dec '18

06 Dec '18

Hi, we are running a RHV 4.1 installation which is working fine except one issue: We have a Network which is only used for fencing(power Management via ilo), each host has an interface with this network and a custom ip, for this to work we need a few custom routes. At the moment we add the new routes via a plain route file under /etc/sysconfig/network-scripts/, but the engine flags this interface then as out-of-sync. How can we persist those changes across reboots and still be able to add new devices via the UI ? This looked promising but isnt working: https://ovirt.org/develop/release-management/features/network/networkreload… Thanks for any Help :)

The built in group Everyone is troublesome.

So all my VMs are inheriting system permissions from group everyone and giving all my users access to all my VMs, in ovirt 4.2. Is there a best practices guide or any recommendation on how to clear this up? Clicking remove on everyone does not work because Ovirt won't allow me to remove a built in account.

Debugging "non_operational" host during self-hosted deploy
by Mikael Öhman 04 Dec '18

04 Dec '18

The "bootstrap_local_vm.yml" playbook fails at the end, during the task "Wait for the host to be up" Looking through the ovirt-hosted-engine-setup-bootstrap_local_vm log, I found the reason is supposed to be: "status": "non_operational", "status_detail": "network_unreachable", But that's it. I can't find anything wrong with any networks, neither on the host or in the partly-prepared HE VM. Is there some verbose information I can dump to find out why it thinks the network is unreachable? I can't find any logs indicating any issues until this step.

Need some magic here ... - 2 hosts CentOS 7.5.1804 with all the patch available, in the cluster - hosted engine from rpm ovirt-engine-appliance-4.2-20181113.1.el7.noarch with all the patch as well (manager Version 4.2.7.5-1.el7) 1) I re-install the hosts and the hosted engine from scratch 2) I imported the ISO, export and DATA domain from the SAN 3) I went to the DATA domain in the VM Import tab where I saw all the VMs 4) I imported the VM one after one BUT .... One of the VM (Windows 10 x64) can't be import because of the error in the subject of this thread. In the engine.log file I get 2018-12-01 19:17:50,387-05 WARN [org.ovirt.engine.core.bll.exportimport.ImportVmFromConfigurationCommand] (default task-4) [92c96b3c-38c5-42ab-b81c-11413ea32ccd] Validation of action 'ImportVmFromConfiguration' failed for user admin@internal-authz.

I also tried to put the DefaultWindowsTimeZone empty but engine-config doesn't allow that neither if I put a * The VM is on iscsi device so can't go see the vm files to fix it directly on the fs 10 hours since I start to fix this import thing ;-( If someone has some magic for me, I will be a nice gift before christmas

[OT] Xen/Oracle VM under Qemu-kvm/oVirt
by Gianluca Cecchi 04 Dec '18

04 Dec '18

Hello, I have to do a test on Oracle VM 3.4.4 that is based on Xen 4.4.4. The test aims in simulating storage migration in OVM, where I have to migrate also the so called server pool file system, that requires a special procedure. I see that some guys wrote here to ask about OVM to oVirt migrations, so there could be some expertise in this field. I'm just trying to proceed with the hypervisor steps (Oracle VM Server), that is the more difficult part, I suppose. I'm testing at the moment on a Fedora 29 system, using qemu-kvm, setting host-pass-through for the vm dedicated to the Oracle VM Hypervisor. I already tested nested virtualization (with oVirt for some vms) inside this system, so the host part should be ok. I have set disks as scsi and vnic as e1000 Installation gone ok but at reboot I see cpu stuck and no prompt yet see here: https://drive.google.com/file/d/1sAEO-W0-OLIGSugxIwSLRBx3WXXoK1yx/view?usp=… I have not yet understood exactly the reason of complain... Any one already able to create a Xen (or Oracle VM) nested environment inside qemu-kvm? The OS of the Xen dom0 should be based on Oracle Linux 6.x I can also test trying to install on oVirt if anyone on the list already ran through this path. Thanks in advance for any help or pointers. I'm also going and post on Oracle VM forum... Gianluca

Best Openstack version to integrate with oVirt 4.2.7
by Gianluca Cecchi 04 Dec '18

04 Dec '18

Hello, do you think it is ok to use Rocky version of Openstack to integrate its services with oVirt 4.2.7 on CentOS 7? I see on https://repos.fedorapeople.org/repos/openstack/ that, if Rocky is too new, between the older releases available there are, from newer to older: Queens Pike Ocata Newton At the moment I have two separate lab environments: oVirt with 4.2.7 Openstack with Rocky (single host with packstack allinone) just trying first integration steps with these versions, it seems I'm not able to communicate with glance, because I get in engine.log 2018-11-10 17:32:58,386+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-51) [e2fccee7-1bb2-400f-b8d3-b87b679117d1] Not Found (OpenStack response error code: 404) Nothing in glance logs on openstack, apparently. In my test I'm using http://xxx.xxx.xxx.xxx:9292 as provider url checked the authentication check box and glance user with its password 35357 as the port and services as the tenant a telnet on port 9292 of openstack server from engine to openstack is ok similar with cinder I get: 2018-11-10 17:45:42,226+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-50) [32a31aa7-fe3f-460c-a8b9-cc9b277deab7] Not Found (OpenStack response error code: 404) So before digging more I would lile to be certain which one is currently the best combination, possibly keeping as fixed the oVirt version to 4.2.7. Thanks, Gianluca

Hello Team, We are running a setup of 3-way replica HC gluster setup configured during the initial deployment from the cockpit console using ansible. NODE1 - /dev/sda (OS) - /dev/sdb ( Gluster Bricks ) * /gluster_bricks/engine/engine/ * /gluster_bricks/data/data/ * /gluster_bricks/vmstore/vmstore/ NODE2 and NODE3 with a similar setup. Hosted engine was running on node2. - While moving NODE1 to maintenance mode along with stopping the gluster service as it prompts before, Hosted engine instantly went down. - I start the gluster service back on node1 and start the hosted engine again and found hosted engine started properly but getting crashed again and again within frames of second after a successful start because HE itself stopping glusterd on node1. (not sure) but cross-verified by checking glusterd status. *Is it possible to clear pending tasks or not let the HE to stop glusterd on node1?* *Or we can start the HE using other gluster node?* https://paste.fedoraproject.org/paste/Qu2tSHuF-~G4GjGmstV6mg -- ABHISHEK SAHNI IISER Bhopal

From Self-hosted engine to standalone engine
by Punaatua PK 04 Dec '18

04 Dec '18

Hello, we currently have a self-hosted engine on gluster with 3 hosts. We want to have the engine on a single machine on a standalone KVM. We did the following steps on our test platform. - Create a VM on a standalone KVM - Put the self hosted engine into global maintenance - Shut the self-hosted engine - Copy the self-hosted engine image disk (by browsing into the gluster engine volume) by using linux dd command to the standalone KVM - Reusing the self-hosted engine's MAC address on the new standalone VM - Starting the standalone VM which use the self-hosted image disk previously copied on the standalone KVM - Log in the engine and then undeploy the hosted-engine by re-installing all the host and go for UNDEPLOY on the self-hosted section - Stop ovirt-ha-agent and ovirt-ha-broker Everything seems to be ok for now. What do you think about our process ? (to go from self-hosted to standalone) Do you have any idea on what should be checked ? Thank you (We wanted to go out from self-hosted engine, because we don't really master this deployment)

FCoE wont initialize on reboot oVirt 4.2.
by Jacob Green 03 Dec '18

03 Dec '18

I have HP BL460c Gen9 blades with BCM57840 NetXtreme II 10/20-Gigabit Ethernet via a HP Virtual connection. In my ovirt 4.1 environment I have fibre channel working great. However in the new environment that I want to bring the data domain over too ultimately, I am having issues with ovirt interfering with the hosts ability to see the Fiber Channel storage. If i build a clean CentOS 7 installation and get my FCoE module installed and Fiber channel set up on my appropriate interfaces, it works and sees the fiber channel interface every time I type fcoeadm -i, I can reboot a million times, does not go away. However once I turn it into a oVirt 4.2 node and add it to my environment and reboot the blade it is hit or miss if fcoeadm -i is going to return interface information. If I then type "systemctl restart network" my fiber channel comes online, but I should not need to do this. I can see in my dmesg logs that the fiber channel is initializing on boot. [ 39.465578] cnic: QLogic cnicDriver v2.5.22 (July 20, 2015) [ 39.465594] bnx2x 0000:06:00.2 eno51: Added CNIC device [ 39.475618] bnx2x 0000:06:00.3 eno52: Added CNIC device [ 39.495575] bnx2fc: QLogic FCoE Driver bnx2fc v2.11.8 (October 15, 2015) [ 39.505971] bnx2fc: bnx2fc: FCoE initialized for eno52.

[ 39.516654] bnx2fc: [06]: FCOE_INIT passed Reminder I have not added a FC storage domain yet, because I need to turn off and detach the domain from the old 4.1 environment first. However that should not keep the fiber channel interfaces from coming up... And I need to know its working before I do that. Below is what an fcoeadm -i should return when it seems to be working. ____________________________________________________________________________________________________ fcoeadm -i Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno51 OS Device Name: host10 Node Name: 0x50060b0000c27a05 Port Name: 0x50060b0000c27a04 Fabric Name: 0x1000c4f57c218ff4 Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x0a025c State: Online Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno52 OS Device Name: host11 Node Name: 0x50060b0000c27a07 Port Name: 0x50060b0000c27a06 Fabric Name: 0x1000c4f57c21979d Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x14037b State: Online ____________________________________________________________________________________________________ However if I reboot the node from the ovirt console and wait a few minutes after it has rebooted then type fcoeadm -i I get the following. fcoeadm -i fcoeadm: No action was taken Try 'fcoeadm --help' for more information. it is not until I perform a systemctl restart network, that I get the correct output from above. Any help or insight into fiber channel with ovirt 4.2 would be greatly appreciated. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690
