oVirt API access when using Keycloak
by jonas＠rabe.ch 22 Sep '22

22 Sep '22

Hello all I just recently installed a fresh oVirt appliance. Now I want to use the API to perform some actions but fail to provide the correct username. Can you help? Here's my script: import ovirtsdk4 as sdk from getpass import getpass dc_name = "Default" clu_name = "Default" connection = sdk.Connection( url="https://ovirt-engine-test.admin.int.rabe.ch/ovirt-engine/api", username="admin@ovirt", password=getpass(), # ca_file="/etc/pki/ovirt-engine/ca.pem", insecure=True, ) ... That's the error I get: Traceback (most recent call last): File "/home/user/ovirt_iso_script/./setup_networks.py", line 25, in <module> dc = next(d for d in dcs_svc.list() if d.name == dc_name) File "/usr/lib64/python3.10/site-packages/ovirtsdk4/services.py", line 6863, in list return self._internal_get(headers, query, wait) File "/usr/lib64/python3.10/site-packages/ovirtsdk4/service.py", line 202, in _internal_get context = self._connection.send(request) File "/usr/lib64/python3.10/site-packages/ovirtsdk4/__init__.py", line 371, in send return self.__send(request) File "/usr/lib64/python3.10/site-packages/ovirtsdk4/__init__.py", line 389, in __send self.authenticate() File "/usr/lib64/python3.10/site-packages/ovirtsdk4/__init__.py", line 382, in authenticate self._sso_token = self._get_access_token() File "/usr/lib64/python3.10/site-packages/ovirtsdk4/__init__.py", line 624, in _get_access_token raise AuthError( ovirtsdk4.AuthError: Error during SSO authentication access_denied : Cannot authenticate user No valid profile found in credentials..

cancel export task - no qemu-img process on host
by goosesk blabla 22 Sep '22

22 Sep '22

Hi, i tried to find way how to cancel hanged export task. I found that there should be some hidden possibility, but it is still not released and i cannot find how to allow it. i found how to remove this task directly from pg database on engine, but i am not sure if this also will unlock that VM. i cannot kill it by qemu-img process, because this process is not running. stucked VM is ubuntu 20.04 with 3 disks 20 + 80 + 300GB . Already running more than 12 hours and still did not start making ova file (checking in export folder) . qemu-img process on the host is missing . i tried to export smaller VM 7GB and it was successfully done by 2 minutes. During export qemu-img process was running on the host. Thank you for any help. BR jan

VMs hang periodically: gluster problem?
by Diego Ercolani 22 Sep '22

22 Sep '22

Hello, I have a cluster made by 3 nodes in a "self-hosted-engine" topology. I implemented the storage with gluster implementation in 2 replica + arbiter topology. I have two gluster volumes glen - is the volume used by hosted-engine vm gv0 - is the volume used by VMs The physical disks are 4TB SSD used only to accomodate VMs (also hosted-engine) I have continuos VMs hangs, even hosted-engine, this give full of troubles as I have continuous hangs by hosted-engine and this happen asyncrounosly even while there is management operation on VMs (mobility, cloning...) after a while it happens that the VM is freed but in the VMs I have in console kernel complaining by CPU hang or timer hangs and the solution is only to shutdown/poweroff the VM... even hosted engine in fact it happens that hosted-engine -vm-status give "state=EngineUpBadHealth" This is the log during the event in the host while there is the event: Sep 01 07:48:58 ovirt-node3.ovirt NetworkManager[1923]: <info> [1662018538.0166] device (vnet73): state change: activated -> unmanaged (reason 'unmanaged', sys-iface-state: 'removed') Sep 01 07:48:58 ovirt-node3.ovirt NetworkManager[1923]: <info> [1662018538.0168] device (vnet73): released from master device ovirtmgmt Sep 01 07:48:58 ovirt-node3.ovirt libvirtd[2496]: Unable to read from monitor: Connection reset by peer Sep 01 07:48:58 ovirt-node3.ovirt libvirtd[2496]: internal error: qemu unexpectedly closed the monitor: 2022-09-01T07:48:57.930955Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,bus=pci.6,addr=0x0,drive=libvirt-1-format,id=ua-0a1a501c-fc45-430f-bfd3-076172cec406,bootindex=1,write-cache=on,serial=0a1a501c-fc45-430f-bfd3-076172cec406,werror=stop,rerror=stop: Failed to get "write" lock Is another process using the image [/run/vdsm/storage/3577c21e-f757-4405-97d1-0f827c9b4e22/0a1a501c-fc45-430f-bfd3-076172cec406/f65dab86-67f1-46fa-87c0-f9076f479741]?

iSCSI domain not seen by a node if the topology differ from the topology of the other nodes?
by Diego Ercolani 21 Sep '22

21 Sep '22

Hello, I think I0ve found another issue: I have the three node that are under heavy test and, after having problem with gluster I configured them to use with iSCSI (without multipath now) so I configured via the gui a new iscsi data domain using a single target under a single VLAN. I suspect there is an issue reporting the correct volume in my case: I try to explain. This are the scsi devices in the three nodes: [root@ovirt-node2 ~]# lsscsi [4:0:0:0] disk ATA ST4000NM000A-2HZ TN02 /dev/sda [5:0:0:0] disk ATA Samsung SSD 870 2B6Q /dev/sdb [6:0:0:0] disk IBM 2145 0000 /dev/sdc [N:0:1:1] disk Force MP600__1 /dev/nvme0n1 [root@ovirt-node3 ~]# lsscsi [0:0:0:0] disk ATA Samsung SSD 870 2B6Q /dev/sda [6:0:0:0] disk IBM 2145 0000 /dev/sdb [N:0:0:1] disk WD Blue SN570 500GB__1 /dev/nvme0n1 [root@ovirt-node4 ~]# lsscsi [3:0:0:0] disk ATA ST4000NM000A-2HZ TN02 /dev/sda [4:0:0:0] disk ATA KINGSTON SA400S3 1103 /dev/sdb [5:0:0:0] disk IBM 2145 0000 /dev/sdc So you see, the SCSI target (IBM 2145) are mapped as /dev/sdc in node2 and node4, but in node3 is mapped as /dev/sdb.

VM Down With "Bad Volume Specification"

I had occasion to shutdown a VM for the purpose of adding RAM and processor to it and the VM willnot boot back up. I'm seeing "VM Issabel_PBX is down with error.

It's important to clarify (for yourself, mainly) what exactly you test, what's important, what's expected, etc. > After disconnecting the KVM hosts hosting the SHE, there was a long timeout until switching the Self-Hosted-Engine to another host as expected. I suggest studying the ha-agent logs, /var/log/ovirt-hosted-engine-ha/agent.log. Much of the relevant code is in ovirt_hosted_engine_ha/agent/states.py (in the git repo, or under /usr/lib/python3.6/site-packages/ on your machine). > Also, there took a relatively long time to take over the HA VMs from the failing server. That's a separate issue, about which I personally know very little. You might want to start a separate thread about it. I do know, though, that if you keep the storage connected, the host might be able to keep updating VM leases on the storage. See e.g.: https://www.ovirt.org/develop/release-management/features/storage/vm-leases… I didn't check the admin guide, but I suppose it has some material about HA VMs. > Is there a configuration where I can reduce the SHE timeout to make this recover process faster? IIRC there is nothing user-configurable. You can see most relevant constants in ovirt_hosted_engine_ha/agent/constants.py{,.in}. Nothing stops you from changing them, but please note that this is somewhat risky, and I strongly suggest to do very careful testing with your new settings. It might make sense to try to methodically go through all the possible state changes in the above state machine. The general assumption is that network and storage, for critical setups, are redundant, and that the engine itself is not considered critical, in the sense that if it's dead, all your VMs are still alive. And also, that it's more important to not corrupt VM disk images (e.g. by starting the VM concurrently on two hosts) than to keep the VM alive. Best regards, -- Didi

all active domains with status unknown in old 4.3 cluster
by Jorick Astrego 21 Sep '22

21 Sep '22

Hi, Currently I'm debugging a client's ovirt 4.3 cluster. I was adding two new gluster domains and got a timeout "VDSM command AttachStorageDomainVDS failed: Resource timeout: ()" and "Failed to attach Storage Domain *** to Data Center **". Then I had to restart ovirt-engine and now all the domains including NFS domains have status "unknown" and I see "VDSM command GetStoragePoolInfoVDS failed: Resource timeout: ()" in the events. Anyone fixed this before or have any tips?

Snapshot task stuck at oVirt 4.4.8
by nicolas＠devels.es 21 Sep '22

21 Sep '22

Hi, We're running oVirt 4.4.8 and one of our users tried to create a snapshot on a VM. The snapshot task got stuck (not sure why) and since then a "locked" icon is being shown on the VM. We need to remove this VM, but since it has a pending task, we're unable. The ovirt-engine log shows hundreds of events like: [2022-09-20 09:23:09,286+01 INFO [org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-27) [2769dad5-3ec3-4c46-90a2-924746ea8d97] Command 'CreateSnapshotForVm' (id: '4fcb6ab7-2cd7-4a0c-be97-f6979be25bb9') waiting on child command id: 'cbb7a2c0-2111-4958-a55d-d48bf2d8591b' type:'CreateLiveSnapshotForVm' to complete An ovirt-engine restart didn't make any difference. Is there a way to remove this task manually, even changing something in the DB? Thanks.
