assign a specific user to a specific vm
by eevans＠digitaldatatechs.com 17 Apr '20

I'm not sure if I'm missing something or not, but I haven't seen how to assign a specific user to a specific vm. Is there a way to do that? When users login, they see all the machines. I'd like them to see just the one they need to login to. Thanks in advance for your help. Eric

VM's in status unknown
by kim.kargaard＠noroff.no 17 Apr '20

17 Apr '20

Hi, We have a few Windows 10 VM's running on our ovirt 4.3, where when you shutdown the VM from within Windows, that VM does not shut down but gets a status of unknown in ovirt and one cannot do anything to the machines within the web gui. This seems to specfically be related to that Windows 10 template that we have created. Any ideas? Also, any ideas on how one can shut these machines down? Thanks Kim

Update Conflicts
by Christian Reiss 17 Apr '20

17 Apr '20

Hey folks, Some weeks ago I installed oVirt on top of a fresh CentOS 7 installation. I went ahead according to the official setup, which is basically to actiate a repo and then install via engine. When I try to run "yum update" on the hosts, I get a dependency error: --> Finished Dependency Resolution Error: Package: libvirt-daemon-driver-storage-4.5.0-23.el7_7.6.x86_64 (updates) Requires: libvirt-daemon-driver-storage-gluster = 4.5.0-23.el7_7.6 Installed: libvirt-daemon-driver-storage-gluster-4.5.0-23.el7_7.5.x86_64 (@updates) libvirt-daemon-driver-storage-gluster = 4.5.0-23.el7_7.5 Error: Package: vdsm-gluster-4.30.40-1.el7.x86_64 (@ovirt-4.3) Requires: vdsm = 4.30.40-1.el7 Removing: vdsm-4.30.40-1.el7.x86_64 (@ovirt-4.3) vdsm = 4.30.40-1.el7 Updated By: vdsm-4.30.43-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.43-1.el7 Available: vdsm-4.30.8-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.8-1.el7 Available: vdsm-4.30.9-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.9-1.el7 Available: vdsm-4.30.11-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.11-1.el7 Available: vdsm-4.30.12-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.12-1.el7 Available: vdsm-4.30.13-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.13-1.el7 Available: vdsm-4.30.14-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.14-1.el7 Available: vdsm-4.30.15-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.15-1.el7 Available: vdsm-4.30.16-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.16-1.el7 Available: vdsm-4.30.17-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.17-1.el7 Available: vdsm-4.30.18-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.18-1.el7 Available: vdsm-4.30.19-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.19-1.el7 Available: vdsm-4.30.20-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.20-1.el7 Available: vdsm-4.30.21-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.21-1.el7 Available: vdsm-4.30.22-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.22-1.el7 Available: vdsm-4.30.23-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.23-1.el7 Available: vdsm-4.30.24-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.24-1.el7 Available: vdsm-4.30.25-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.25-1.el7 Available: vdsm-4.30.26-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.26-1.el7 Available: vdsm-4.30.28-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.28-1.el7 Available: vdsm-4.30.29-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.29-1.el7 Available: vdsm-4.30.30-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.30-1.el7 Available: vdsm-4.30.31-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.31-1.el7 Available: vdsm-4.30.32-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.32-1.el7 Available: vdsm-4.30.33-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.33-1.el7 Available: vdsm-4.30.34-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.34-1.el7 Available: vdsm-4.30.35-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.35-1.el7 Available: vdsm-4.30.36-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.36-1.el7 Available: vdsm-4.30.37-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.37-1.el7 Available: vdsm-4.30.38-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.38-1.el7 Available: vdsm-4.30.39-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.39-1.el7 Available: vdsm-4.30.42-1.el7.x86_64 (ovirt-4.3) vdsm = 4.30.42-1.el7 Error: Package: libvirt-daemon-driver-storage-gluster-4.5.0-23.el7_7.5.x86_64 (@updates) Requires: libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.5 Removing: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.5.x86_64 (@updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.5 Updated By: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.6.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.6 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7.x86_64 (base) libvirt-daemon-driver-storage-core = 4.5.0-23.el7 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.1.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.1 Available: libvirt-daemon-driver-storage-core-4.5.0-23.el7_7.3.x86_64 (updates) libvirt-daemon-driver-storage-core = 4.5.0-23.el7_7.3 What did I miss here?

Multitenant scenario in oVirt
by Michal Gutowski 17 Apr '20

17 Apr '20

Hi oVirt community, I'm playing with a multitenant use-case in oVirt 3.4.6... My setup is as follows: - I have two working Data Centers (DC1 and DC2) - I created two additional users DC1-admin and DC2-admin - In DC1 permission settings I've added DC1-admin as a user with a builtin DataCenterAdmin Role. - In DC2 permission settings I've added DC2-admin as a user with a builtin DataCenterAdmin Role. Now in terms of permissions all is good: DC1-admin is not able to modify anything in DC2 and DC2-admin is not able to modify anything in DC1. However in both the Admin Portal and the VM Portal DC1-admin and DC2-admin can still see all other datacenter resources. My expectation was that if I login to the Admin Portal as e.g. DC2-admin I will only see DC2 datacenter in the GUI and nothing else. Same with VM Portal. I played with different user settings but I couldn't make it work... I think the problem is that whatever user you create it will always belong to the build-in "everyone" group and inherit permission to see everything in the portal. Is it possible to achieve a scenario where e.g. DC2-admin will login to the Admin Portal and only see resources that belong to DC2 and nothing else? Thanks, Michal

Sometimes paused due to unknown storage error on gluster
by Gianluca Cecchi 16 Apr '20

16 Apr '20

Hello, having deployed oVirt 4.3.9 single host HCI with Gluster, I see some times VM going into paused state for the error above and needing to manually run it (sometimes this resumal operation fails). Actually it only happened with empty disk (thin provisioned) and sudden high I/O during the initial phase of install of the OS; it didn't happened then during normal operaton (even with 600MB/s of throughput). I suspect something related to metadata extension not able to be in pair with the speed of the physical disk growing.... similar to what happens for block based storage domains where the LVM layer has to extend the logical volume representing the virtual disk My real world reproduction of the error is during install of OCP 4.3.8 master node, when Red Hat Cores OS boots from network and wipes the disk and I think then transfer an image, so doing high immediate I/O. The VM used as master node has been created with a 120Gb thin provisioned disk (virtio-scsi type) and starts with disk just initialized and empty, going through PXE install. I get this line inside events for the VM Mar 27, 2020, 12:35:23 AM VM master01 has been paused due to unknown storage error. Here logs around the time frame above: - engine.log https://drive.google.com/file/d/1zpNo5IgFVTAlKXHiAMTL-uvaoXSNMVRO/view?usp=… - vdsm.log https://drive.google.com/file/d/1v8kR0N6PdHBJ5hYzEYKl4-m7v1Lb_cYX/view?usp=… Any suggestions? The disk of the VM is on vmstore storage domain and its gluster volume settings are: [root@ovirt tmp]# gluster volume info vmstore Volume Name: vmstore Type: Distribute Volume ID: a6203d77-3b9d-49f9-94c5-9e30562959c4 Status: Started Snapshot Count: 0 Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: ovirtst.mydomain.storage:/gluster_bricks/vmstore/vmstore Options Reconfigured: performance.low-prio-threads: 32 storage.owner-gid: 36 performance.read-ahead: off user.cifs: off storage.owner-uid: 36 performance.io-cache: off performance.quick-read: off network.ping-timeout: 30 features.shard: on network.remote-dio: off cluster.eager-lock: enable performance.strict-o-direct: on transport.address-family: inet nfs.disable: on [root@ovirt tmp]# What about config above, related to eventual optimizations to be done based on having single host?

Hi, I'm trying to set up one of our nodes with PCI passthrough but there is a dead lnk in the documentation for the kernel boot parameter section of creating a new host. https://www.ovirt.org/documentation/admin-guide/sect-Explanation_of_Setting… Anyone know where this went or can help me with the options?

How to load VMs after importing a domain
by Shareef Jalloq 16 Apr '20

16 Apr '20

I've followed the online instructions on importing a pre-configured domain into a new data centre but I can't see how to import the VMs. The documentation just says, "You can now import virtual machines and templates from the storage domain to the data center." with no other info. What do I need to do in order to get my VMs up and running? Cheers, Shareef.

Single SPM Host orphaned from ovirt-engine, cannot confirm host rebooted or maintenance host.
by Terry 16 Apr '20

16 Apr '20

We have number of clusters connected to ovirt-engine. Some of these are single host clusters (running ovirt-release43-4.3.5.2-1 on CentOS7) with local storage. Recently, ovirt-engine started reporting one of these hosts NonResponsive, VMs were still running on the host but ovirt seems unable to communicate with it, testing shows no issues connecting engine -> host:vdsm and likewise the host can communicate with the engine on port 80 and 443. The host in question cannot be managed via IPMI for power management but we are able to perform an SSH reboot via the engine interface. We opted to login to the running virtual machines, shut them down and issue the SSH reboot from the engine. The server changes to rebooting status for some time and then reports NonResponsive state. We are unable to maintenance the host or confirm host has been rebooted manually as we are presented with the following "Error while executing action: Cannot perform confirm 'Host has been rebooted'. Another power management action is already in progress." The VDSM logs on the host in question are continually showing: 2020-04-16 08:23:51,478+0000 INFO (vmrecovery) [vds] recovery: waiting for storage pool to go up (clientIF:711) 2020-04-16 08:23:52,332+0000 INFO (jsonrpc/7) [vdsm.api] FINISH getStoragePoolInfo error=Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) from=::ffff:10.10.1.252,33680, task_id=420249a4-55c0-436d-92c7-ea1286a0e287 (api:52) 2020-04-16 08:23:52,332+0000 ERROR (jsonrpc/7) [storage.TaskManager.Task] (Task='420249a4-55c0-436d-92c7-ea1286a0e287') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in getStoragePoolInfo File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2550, in getStoragePoolInfo pool = self.getPool(spUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 351, in getPool raise se.StoragePoolUnknown(spUUID) StoragePoolUnknown: Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) 2020-04-16 08:23:52,333+0000 INFO (jsonrpc/7) [storage.TaskManager.Task] (Task='420249a4-55c0-436d-92c7-ea1286a0e287') aborting: Task is aborted: "Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',)" - code 309 (task:1181) During this period, the following is observed in the engine logs: 2020-04-16 08:23:52,307Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM compute01.ovirt.local command SpmStatusVDS failed: Message timeout which can be caused by communication issues 2020-04-16 08:23:52,307Z ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.SpmStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] Command 'SpmStatusVDSCommand(HostName = compute01.ovirt.local, SpmStatusVDSCommandParameters:{hostId='67dc53da-d5ee-461e-87de-2ca6dd78637f', storagePoolId='6baea5dc-b049-47c2-a94f-5229c37c62d0'})' execution failed: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues 2020-04-16 08:23:52,346Z ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.GetStoragePoolInfoVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] Failed in 'GetStoragePoolInfoVDS' method 2020-04-16 08:23:52,355Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] EVENT_ID: IRS_BROKER_COMMAND_FAILURE(10,803), VDSM command GetStoragePoolInfoVDS failed: Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',) 2020-04-16 08:23:52,356Z ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-31) [] IrsBroker::Failed::GetStoragePoolInfoVDS: IRSGenericException: IRSErrorException: Failed to GetStoragePoolInfoVDS, error = Unknown pool id, pool not connected: (u'6baea5dc-b049-47c2-a94f-5229c37c62d0',), code = 309 The metadata file for the local storage domain looks fine?

Normally in a case like this we would confirm the host has been manually rebooted but we're unable to do that. How can I clear the power management action that ovirt-engine thinks is in progress?

Here is my configuration: - 2 Hosts - Host 1 - nic 1 - ovirtmgmt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.50/24 VLAN 25 - Host 2 - nic 1 - ovirtmgmnt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.51/24 - VLAN 25 Migration network is setup as follows: - Assign - Yes - Required - Yes - VM Network - No (tried it with VM Nework = Yes with same results) - Migration Network - Yes I think I've got something fundamentally wrong with my host networking but I can't figure it out. Appreciate the help.

NUMA Pinning bug with Hugepages?
by Alan G 15 Apr '20

15 Apr '20

Hi, I seem to have found an issue when trying to setup a high performance VM utilising hugepages and NUMA pinning. The VM is configured for 32GB RAM and uses hugepages of size 1G. The host has two NUMA nodes each having 64GB RAM (for 128GB total system RAM). No other VMs are running or otherwise pinned to the host. The VM is pinned to node 0. And the required hugepages are allocated with echo 32 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages I then attempt to start the VM and get a pop-up error saying "cannot accommodate memory of VM's pinned virtual NUMA nodes within host's physical NUMA nodes". However, if I remove the hugepages from node 0 echo 0 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages Start the VM and then immediately re-create the hugepqages then everything works as expected. It seems to me that oVirt is considering the hugepages as allocated memory even if they are not in use. Is this correct? Thanks, Alan

upgrade VM cluster compatibility version
by Bill James 15 Apr '20

15 Apr '20

I'm trying to upgrade my cluster to 4.3. Currently its running 4.2.8.2-1.el7. But the cluster compatibility version is 3.6. I try to change that and it says I need to edit the VM. https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks.h… says: *Important:* An error message may warn that some virtual machines and templates are incorrectly configured. To fix this error, edit each virtual machine manually. The *Edit Virtual Machine* window provides additional validations and warnings that show what to correct. Sometimes the issue is automatically corrected and the virtual machine’s configuration just needs to be saved again. After editing each virtual machine, you will be able to change the cluster compatibility version. I edit the VM and there are no errors or warnings. I see no way to change the cluster compatibility level on a VM. How do I change the Custom Compatibility Version?? -- This email, its contents and attachments contain information from J2 Global, Inc. and/or its affiliates which may be privileged, confidential or otherwise protected from disclosure.

Get OAuth token locally without password?
by Chris Adams 14 Apr '20

14 Apr '20

I'm working on a cron job to run on the engine to do some tasks via the API. Is there a way I can get an API OAuth token created without actually storing a password? For example, some script that can be run to directly create a session in the database and return the token. Obviously this _can_ be done, it's a matter of knowing the right bits to do (so basically wondering if that has already been written). I only have internal users, so no external authentication store available. -- Chris Adams <cma(a)cmadams.net>

Migrate engine to another storage domain?
by Simon Nylund 14 Apr '20

14 Apr '20

Is there a successful way of migrating an up and running engine to another storage domain? I've been reading through the archive and tested a few various ways without any success. The only way i found working without errors was deploying a new engine attached to the new storage domain, and import the old data domain for the vms, but then you lose all the settings for the previous engine (ofc). And have to redo all of that.

Total LUN Limitations
by Ryan Chewning 13 Apr '20

13 Apr '20

I'm hoping that someone might be able to clarify a limitation found in the RedHat documentation. The documentation indicates that there is a limitation of 300 LUNS per block based storage device. Does this include LUNs which are directly mapped to a VM? Or does this referrer to LUNs which serve as a storage repository for ISOs / VM disks?

Host fails to enter in maintenance due to migration failure
by Vinícius Ferrão 13 Apr '20

13 Apr '20

Hello, I’ve a host that’s preparing to maintenance for almost 20 hours now. There’s a huge VM on it, with 32 gigs of RAM and this VM is failing migration. So, there’s a way to cancel prepare for maintenance, so the host can stop trying this migration that’s end up failing? I can just shutdown the VM to do the maintenance on the host... Thanks,

Looking through the logs I saw references to the blocksize but since that is contained in the ansible scripts which get downloaded to the host I gave up finding the source versions to try to see it I could get it going beyond that failing step. Anyway, thanks for informing me, Regards, Joop

engine certificate problems in MacOS Catalina
by Jayme 13 Apr '20

13 Apr '20

I recently setup a new ovirt environment using latest 4.3.9 installer. I can't seem to get the novnc client to work for the life of me in safari or chrome on MacOS catalina. I have downloaded the CA from the login page and imported it into keychain and made sure it was fully trusted. In both system and login keychains. Looking at this: https://support.apple.com/en-us/HT210176 seems to suggest that the certificate may be invalid if the issue date is longer than 825 days. The certificate generated by ovirt installer seems to be valid for 5 years. I'm not sure if this is the issue or something else is wrong but if cert length is a problem is there a way for me to re-regenerate a new certificate with a shorter issue period?

One more time
by eevans＠digitaldatatechs.com 13 Apr '20

13 Apr '20

I have thought about the issue with Windows vm's reporting the timezone incorrectly. I reaqlized that just last month, before I created my vm's that the Daylight Savings Time took affect moving our time up 1 hour. SO, based on that, instead of setting my time zone to US Eastern (GMT -5), I set it to SA Western (GMT -4) and the nasty exclamation mark disappeared. This tells me that DST (Daylight Savings Time) is not an option or configurable in Ovirt. I think this should be an easy fix for those of use that are stuck with it. I don't think the rest of the world participates in DST but most of the United States does. It would be nice to have those zones added as a configurable option that would switch on the dates it is nationally indicated to change. I hope the developers read this. Thanks.

DR on hyperconverged deployment
by wodel youchi 13 Apr '20

13 Apr '20

Hi, Need to understand somethings about DR on oVirt-HI - What does mean : Scheduling regular backups using geo-replication (point 3.3.4 RHHI 1.7 Doc Maintaining RHHI) : - Does this mean creating a check-point? - If yes, does this mean that the geo-replication process will sync data up to that check-point and then stops the synchronization, then repeat the same cycle the day after? does this mean that the minimum RPO is one day? - I created a snapshot of a VM on the source Manager, I synced the volume then I executed a DR, The VM was started on the Target Manager but the VM didn't have its snapshot, any idea??? Regards, be safe.
