oVirt disk disappeared after importing iSCSI domain
by gantonjo-ovirt＠yahoo.com 15 Sep '20

15 Sep '20

Hi all oVirt experts. So, I managed to f.. up a VM today. I had one VM running on a oVirt 4.3 cluster, where the disk was located on an iSCSI data domain. I stopped the VM, put the storage domain in maintenance mode, detached adn removed the storage domain from the ovirt 4.3 cluster. Then I imported the storage domain to our new oVirt 4.4.1 cluster, let the process convert it from V4 to V5 format and activated the storage domain in the new cluster. Entering the information page for the imported storage domain, I expected to see "Import VM" and "Import Disk" menus, but these menues did not appear as they did for other storage domains that I successfully had moved from old to new cluster. Clicking "Scan Disks" did not help either. So, now I am stuck with a storage domain where the VM's disk is located, but oVirt is not able to see the disk. What can I do to recover the lost disk from the storage domain? Any CLI commands available in ovirt 4.4.1 would be nice. Thanks in advance for your quick and good help.

Disconnected Server has closed the connection.
by info＠worldhostess.com 15 Sep '20

It seems that the installation is all done, but I have a problem. it takes very long to open the web pages, plus it disconnect all the time. it is impossible to do anything. I can ping the hostname as I set up a sub-domain for it. to be honest, I am new to this and it took me days to get to this point. I think there are some issues with my network settings. if there are any oVirt experts that can check my installation and give me advice about how to improve it, it will be greatly appreciated. I have done an "Installing oVirt as a self-hosted engine using the Cockpit web interface"

Multiple GPU Passthrough with NVLink (Invalid I/O region)
by Vinícius Ferrão 14 Sep '20

14 Sep '20

Hello, here we go again. I’m trying to passthrough 4x NVIDIA Tesla V100 GPUs (with NVLink) to a single VM; but things aren’t that good. Only one GPU shows up on the VM. lspci is able to show the GPUs, but three of them are unusable: 08:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2 16GB] (rev a1) 09:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2 16GB] (rev a1) 0a:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2 16GB] (rev a1) 0b:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 SXM2 16GB] (rev a1) There are some errors on dmesg, regarding a misconfigured BIOS: [ 27.295972] nvidia: loading out-of-tree module taints kernel.

Testing ovirt 4.4.1 Nested KVM on Skylake-client (core i5) does not work
by wodel youchi 14 Sep '20

14 Sep '20

Hi, I've been using my core i5 6500 (skylake-client) for some time now to test oVirt on my machine. However this is no longer the case. I am using Fedora 32 as my base system with nested-kvm enabled, when I try to install oVirt 4.4 as HCI single node, I get an error in the last phase which consists of copying the VM-Manager to the engine volume and boot it. It is the boot that causes the problem, I get an error about the CPU : *the CPU is incompatible with host CPU: Host CPU does not provide required features: mpx* *This is the CPU part from virsh domcapabilities on my physical machine* <cpu> <mode name='host-passthrough' supported='yes'/> <mode name='host-model' supported='yes'> *<model fallback='forbid'>Skylake-Client-IBRS</model> * <vendor>Intel</vendor> <feature policy='require' name='ss'/> <feature policy='require' name='vmx'/> <feature policy='require' name='pdcm'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='clflushopt'/> <feature policy='require' name='umip'/> <feature policy='require' name='md-clear'/> <feature policy='require' name='stibp'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='ssbd'/> <feature policy='require' name='xsaves'/> <feature policy='require' name='pdpe1gb'/> <feature policy='require' name='invtsc'/> <feature policy='require' name='ibpb'/> <feature policy='require' name='amd-ssbd'/> <feature policy='require' name='skip-l1dfl-vmentry'/> </mode> <mode name='custom' supported='yes'> <model usable='yes'>qemu64</model> <model usable='yes'>qemu32</model> <model usable='no'>phenom</model> <model usable='yes'>pentium3</model> <model usable='yes'>pentium2</model> <model usable='yes'>pentium</model> <model usable='yes'>n270</model> <model usable='yes'>kvm64</model> <model usable='yes'>kvm32</model> <model usable='yes'>coreduo</model> <model usable='yes'>core2duo</model> <model usable='no'>athlon</model> <model usable='yes'>Westmere-IBRS</model> <model usable='yes'>Westmere</model> <model usable='no'>Skylake-Server-IBRS</model> <model usable='no'>Skylake-Server</model> <model usable='yes'>Skylake-Client-IBRS</model> <model usable='yes'>Skylake-Client</model> <model usable='yes'>SandyBridge-IBRS</model> <model usable='yes'>SandyBridge</model> <model usable='yes'>Penryn</model> <model usable='no'>Opteron_G5</model> <model usable='no'>Opteron_G4</model> <model usable='no'>Opteron_G3</model> <model usable='yes'>Opteron_G2</model> <model usable='yes'>Opteron_G1</model> <model usable='yes'>Nehalem-IBRS</model> <model usable='yes'>Nehalem</model> <model usable='yes'>IvyBridge-IBRS</model> <model usable='yes'>IvyBridge</model> <model usable='no'>Icelake-Server</model> <model usable='no'>Icelake-Client</model> <model usable='yes'>Haswell-noTSX-IBRS</model> <model usable='yes'>Haswell-noTSX</model> <model usable='yes'>Haswell-IBRS</model> <model usable='yes'>Haswell</model> <model usable='no'>EPYC-IBPB</model> <model usable='no'>EPYC</model> <model usable='no'>Dhyana</model> <model usable='yes'>Conroe</model> <model usable='no'>Cascadelake-Server</model> <model usable='yes'>Broadwell-noTSX-IBRS</model> <model usable='yes'>Broadwell-noTSX</model> <model usable='yes'>Broadwell-IBRS</model> <model usable='yes'>Broadwell</model> <model usable='yes'>486</model> </mode> </cpu> *Here is the lscpu of my physical machine* # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian Address sizes: 39 bits physical, 48 bits virtual CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 94 Model name: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz Stepping: 3 CPU MHz: 954.588 CPU max MHz: 3600.0000 CPU min MHz: 800.0000 BogoMIPS: 6399.96 Virtualization: VT-x L1d cache: 128 KiB L1i cache: 128 KiB L2 cache: 1 MiB L3 cache: 6 MiB NUMA node0 CPU(s): 0-3 Vulnerability Itlb multihit: KVM: Mitigation: Split huge pages Vulnerability L1tf: Mitigation;

oVirt HCI issue: GlusterD refusing to start due to quorum issues for volumes where it isn’t contributing any brick
by thomas＠hoberg.net 14 Sep '20

14 Sep '20

Sorry if it's a duplicate: I go an error on post... And yes I posted it on the Gluster slack first, but I am using Gluster only because the marketing on oVirt HCI worked so well... I got 3 recycled servers for an oVirt test environment first and set those up as 3-node HCI using defaults mostly, 2 replica + 1 arbiter, 'engine', 'vmstore' and 'data' volumes with single bricks for each node. I call these group A. Then I got another set of five machines, let's call them group B, with somewhat different hardware characteristics than group A, but nicely similar between themselves. I wanted to add these to the farm as compute nodes but also use their storage as general GlusterFS storage for a wider use. Group B machines were added as hosts and set up to run hosted-engine, but they do not contribute bricks to the normal oVirt volumes 'engine', 'vmstore' or 'data'. With some Ansible trickery I managed to set up two dispersed volumes (4 data: 1 redundancy) on group B 'scratch' and 'tape', mostly for external GlusterFS use. oVirt picked them up automagically, so I guess they could also be used with VMs. I expect to get more machines and adding them one-by-one to dispersed volumes with a fine balance between capacity and redundancy made me so enthusiastic about oVirt HCI in the first place... After some weeks of fine operation I had to restart a machine from group B for maintenance. When it came back up, GlusterD refuses to come online, because it doesn't have "quorum for volumes 'engine', 'vmstore' and 'data'".... It's a small surprise it doesn't *have* quorum, what's a bigger surprise is that it *asks* for quorum in a volume where it's not contributing any bricks. What's worse is that it then refuses to start serving its bricks for 'scratch' and 'tape', which are now growing apart without any chance of healing. How do I fix this? Is this a bug (my interpretation) or do I fundamentlly misunderstand how Gluster as a hyper scale out file system is supposed to work with potentially thousands of hosts contributing each dozens of bricks to each of hundreds of volumes in a single name space?

OVN Geneve tunnels not been established
by Konstantinos B 11 Sep '20

11 Sep '20

Hi all We have a small installation based on OVIRT 4.3. 1 Cluster is based on Centos 7 and the other on OVIRT NG Node image. The environment was stable till an upgrade took place a couple of months ago. As such we had to re-install one of the Centos 7 node and start from scratch. Even though the installation completed successfully and VMs are created, the following are not working as expected: 1. ovn geneve tunnels are not established with the other Centos 7 node in the cluster. 2. Centos 7 node is configured by ovirt engine however no geneve tunnel is established when "ovn-sbctl show" is issued on the engine. 3. no flows are shown on the engine on port 6642 for the ovs db. Does anyone have any experience on how to troubleshoot OVN on ovirt? Thank you

Failed to create a new VM in ovirt due to "The host did not satisfy internal filter Memory" error
by KISHOR K 10 Sep '20

10 Sep '20

Hi All, I'm new to Ovirt and not having a perfect experience with Ovirt yet. I ran into a strange issue today when I tried to create a new VM with 32GB in ovirt. VM creation basically due to an error, pasted below. Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host host-01 did not satisfy internal filter Memory., The host host-01 did not satisfy internal filter Memory. After some troubleshooting, I found that there was enough available memory (around 120 GB free ) in the host to host new VM and there were around 10 VMs already running on this host. But, I noticed that ovirt is actually scheduling and creating VM based on "Max free Memory for scheduling new VMs" value, which seems to be set/updated based on total allocated memory for all VMs running on the host and it's not really the then consumed memory by running VMs. Can anyone help to explain if it is some kind of bug in ovirt or it expected behavior? If it is expected behavior, is there any possibility to change it to make sure VM is created based on actual free memory? Thanks a lot in advance for your support. /Kishore /Kishore

Hi, why does my ovirt hypervisor node crash when i pull the hypervisor boot drive? The following thread claims that the oVirt node hypervisor should lodad into memory, so boot disk failure shouldn't have any impact on a running node. https://lists.ovirt.org/pipermail/users/2014-December/029771.html Only memory failure should have a impact, and if RAM fails there is a possibility that the hypervisor OS would have crashed regardless. If you load the hypervisor OS into memory there will be moved/combined a point of failure (the boot disk) with another(the RAM). RAM=memory

Hyperconverged set up with Gluster and 6 Nodes
by Holger Petrick 09 Sep '20

09 Sep '20

Dear All, in all documentation to set up oVirt in a Hyperconverged system with Gluster says that it must have 3 Enterprise nodes. In our test environment we set up successfully with oVirt wizard an oVirt cluster with gluster + Arbiter and hosted engine. Is it also possible to build a cluster with 6 nodes? The wizard gives only the option to add 3 nodes. Is this kind of design supported? My idea is, first to set up the Gluster, then install the oVirt nodes and deploy the engine. Would this work? Any documentation avaiable? Thanks Holger

iSCSI multipath issue
by Nick Kas 08 Sep '20

08 Sep '20

Hello evryone, setup ovirt 4.4.1 on CentOS 8.2 as an experiment, and I am trying to get an iSCSI domain working but have issues. The little experimental cluster has 3 hosts. There is an ovirtmgmt network on the default vlan, and two iSCSI network (172.27.0/1.X) with vlans 20/21. ovirtmgmt has all the functions (Data, display, migration etc), and the iSCSI networks nothing yet, and they are not set as required. The SAN device is already serving a few iSCSI volumes to a vmware cluster, so I know things are fine on this end. It has two controllers, and four NICs per controller so a total of 8 NICs, half of the NICS per controller on 172.27.0.X and half on 172.27.1.X. When I create the iSCSI domain, I login to only one of the targets, and add the Volume, all is good and I can use the disc fine. However when I login to more than one of the targets, then I start having issues with the Volume. Even when I enabled multipath in the cluster, and I created a single multipath by selecting both of the 172.27.0/1.X networks, and all the targets, the end result was the same. The hosts have difficulty accessing the volume, they may even swing between 'non-operational' and 'up' if I transfer data to the volume. When I ssh to the hosts and i check things in the command line I also get inconsistent results between hosts, and blocks that appear with lsblk when I first setup iSCSI have dissapeared after I try to actively use the volume. I am new to iSCSI so I am not sure how to debug this. I am not sure if my multipath configuration is correct or not. The documentation on this part was not very detailed. I also tried to remove the domain, and try to experiment with mounting the iSCSI volume from the command line, but I cannot even discover the target from the command line, which is very bizarre. The command iscsiadm --mode discovery --target sendtargets --portal 172.27.0.55 --discover returns the message 'iscsiadm: cannot make connection to 172.27.0.55: No route to host'. Yet through ovirt, and if I select only one target, everything work fine! Any suggestions on how to start debugging this would really be appreciated.

Engine certificate and HTTPS : broken on recent Firefox
by Michaël Couren 08 Sep '20

08 Sep '20

Hi, Is there a "verified"* way to add a valid certificate to an oVirt 4.3 engine ? (or suppress HTTP Strict Transport Security) It is no more possible to add a security exception (on latest Firefox 80.0.1 Linux) and I don't want to use 2 browsers (like sanp-chromium just for oVirt...) *"verified" : I mean we have already tried official doc (many months ago) but with no success Thanks -- Cordialement / Best regards, Michaël Couren, ABES, Montpellier, France.

Re: KeyCloak Integration
by Artur Socha 07 Sep '20

Hi Anton, Just to let you know. I investigated this issue. If you want to use keycloak in version >=10 you would need to define all additional scopes as 'optional client scopes' in your client configuration. In my case, on my test environment, I only had to add 'ovirt-ext=auth:sequence-priority=~' but in your case you may need all listed in error_description: *{"error_description":"Cannot authenticate user Invalid scopes: ovirt-app-api ovirt-ext=revoke:revoke-all ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access.","error":"access_denied"}* This configuration change is required because it has been changed/fixed how 'unknown' scopes are handled in keycloak. Now keycloak must always be aware of all scopes and previously unknown ones were simply ignored. Here is BZ with details: https://bugzilla.redhat.com/show_bug.cgi?id=1849569 best, Artur On Tue, Jun 23, 2020 at 5:03 PM Artur Socha <asocha(a)redhat.com> wrote: > On Tue, 2020-06-23 at 14:41 +0000, Anton Louw wrote: > > > > Hi Artur, > > > > Apologies for the late response.

Storage Domain won't activate
by Gillingham, Eric J (US 393D) 05 Sep '20

05 Sep '20

I recently removed a host from my cluster to upgrade it to 4.4, after I removed the host from the datacenter VMs started to pause on the second system they all migrated to. Investigating via the engine showed the storage domain was showing as "unknown", when I try to activate it via the engine it cycles to locked then to unknown again. /var/log/sanlock.log contains a repeating: add_lockspace e1270474-108c-4cae-83d6-51698cffebbf:1:/dev/e1270474-108c-4cae-83d6-51698cffebbf/ids:0 conflicts with name of list1 s1 e1270474-108c-4cae-83d6-51698cffebbf:3:/dev/e1270474-108c-4cae-83d6-51698cffebbf/ids:0 vdsm.log contains these (maybe related) snippets: --- 2020-09-03 20:19:53,483+0000 INFO (jsonrpc/6) [vdsm.api] FINISH getAllTasksStatuses error=Secured object is not in safe state from=::ffff:137.79.52.43,36326, flow_id=18031a91, task_id=8e92f059-743a-48c8-aa9d-e7c4c836337b (api:52) 2020-09-03 20:19:53,483+0000 ERROR (jsonrpc/6) [storage.TaskManager.Task] (Task='8e92f059-743a-48c8-aa9d-e7c4c836337b') 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 getAllTasksStatuses 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 2201, in getAllTasksStatuses allTasksStatus = self._pool.getAllTasksStatuses() File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 77, in wrapper raise SecureError("Secured object is not in safe state") SecureError: Secured object is not in safe state 2020-09-03 20:19:53,483+0000 INFO (jsonrpc/6) [storage.TaskManager.Task] (Task='8e92f059-743a-48c8-aa9d-e7c4c836337b') aborting: Task is aborted: u'Secured object is not in safe state' - code 100 (task:1181) 2020-09-03 20:19:53,483+0000 ERROR (jsonrpc/6) [storage.Dispatcher] FINISH getAllTasksStatuses error=Secured object is not in safe state (dispatcher:87) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/dispatcher.py", line 74, in wrapper result = ctask.prepare(func, *args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 108, in wrapper return m(self, *a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 1189, in prepare raise self.error SecureError: Secured object is not in safe state --- 2020-09-03 20:44:23,252+0000 INFO (tasks/2) [storage.ThreadPool.WorkerThread] START task 76415a77-9d29-4b72-ade1-53207cfc503b (cmd=<bound method Task.commit of <vdsm.storage.task.Task instance at 0x7fe99c27dea8>>, args=None) (thre adPool:208) 2020-09-03 20:44:23,266+0000 INFO (tasks/2) [storage.SANLock] Acquiring host id for domain e1270474-108c-4cae-83d6-51698cffebbf (id=1, wait=True) (clusterlock:313) 2020-09-03 20:44:23,267+0000 ERROR (tasks/2) [storage.TaskManager.Task] (Task='76415a77-9d29-4b72-ade1-53207cfc503b') 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 "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 336, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/lib/python2.7/site-packages/vdsm/storage/sp.py", line 317, in startSpm self.masterDomain.acquireHostId(self.id) File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 957, in acquireHostId self._manifest.acquireHostId(hostId, wait) File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 501, in acquireHostId self._domainLock.acquireHostId(hostId, wait) File "/usr/lib/python2.7/site-packages/vdsm/storage/clusterlock.py", line 344, in acquireHostId raise se.AcquireHostIdFailure(self._sdUUID, e) AcquireHostIdFailure: Cannot acquire host id: ('e1270474-108c-4cae-83d6-51698cffebbf', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argument')) --- Another symptom is in the hosts view of the engine SPM bounces between "Normal" and "Contending". When it's Normal if I select Management -> Select as SPM I get "Error while executing action: Cannot force select SPM. Unknown Data Center status." I've tried rebooting the one remaining host in the cluster no to avail, hosted-engine --reinitialize-lockspace also seems to not solve the issue. I'm kind of stumped as to what else to try, would appreciate any guidance on how to resolve this. Thank You

Failed to connect to server (code: 1006) connecting to second host noVNC console
by James Loker-Steele 04 Sep '20

04 Sep '20

Hi All, Using OLVM and having an issue connecting to a noVNC console on a secondary host. Im getting the Failed to connect. We are using the standalone host as the deployment of the self hosted kept failing, something about the machine not being able to run virtualised machines even though it can. Added a second kvm host to the management engine. Can create new machines, disks etc. Just when trying to connect to the console using noVNC. Any help would be appreciated.

Upgrade 4.3 to 4.4 node to manager communication error
by Pierre pit 03 Sep '20

03 Sep '20

I have a communication problem between all the nodes and the manager following the upgrade from 4.3 to 4.4. I followed the procedure of update 4.3 to 4.4 everything worked correctly, according to the import export scripts as well as the installation setup on the new manager in 4.4, all is ok. Only after connection to the manager, all the nodes are in a down state, there is no more communication between the manager newly installed in 4.4 and the nodes still in production in 4.3. In the manager I have this message for all the nodes: ` VDSM virtdell8 command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on signature algorithm: SHA256withRSA` And on the nodes: ` 2020-09-01 17:38:13,083+0200 ERROR (Reactor thread) [ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: SSLError, address: ::ffff:XXX.XXX.XXX.XXX (sslutils:264) vdsm[4400]: ERROR ssl handshake: SSLError, address: ::ffff:XXX.XXX.XXX.XXX` After a search on the forums I found a similar error on version 4.2 only the solution of comment `ssl_excludes` in the `/etc/vdsm/vdsm.conf` file but does not apply to my problem. I unfortunately had to backtrack because it was no longer possible to control ovirt and use the manager for our production. the new machine with the manager in 4.4 is offline while a solution is found Do you know where should I look in order to solve this problem? thank you in advance Pierre

Re: [ovirt 4.2]The snapshot is deleted after restoring the snapshot
by Strahil Nikolov 03 Sep '20

If you have snapshots like A -> B -> C and you restore A , it is normal to loose B & C. After all when you restore A , B & C never happened. Otherwise , ovirt should clone the snapshots in separate images and that is not the requested, right ?

When I call the snapshot recovery api (POST /ovirt-engine/api/vms/{vm:id }/snapshots/{snapshot:id}/restore) to restoe the first snapshot, I found that the next few snapshots were deleted, and it was normal when I restored the last snapshot. Why does the snapshot with the earlier recovery time delete the subsequent snapshot? The vm's os is centos. Hope get help from you soon, Thank you.

Was it ever solved to install hosted engine with ovn? I tried a few years ago, got it almost to work but then gave up.

How to Backup a VM
by Stefan Wolf 03 Sep '20

Hello to all I try to backup a normal VM. But It seems that I don't really understand the concept. At first I found the possibility to backup with the api https://www.ovirt.org/documentation/administration_guide/#Setting_a_storage…. Create a snapshot of the VM, finding the ID of the snapshot and the configuration of the VM makes sense to me. But at this point, I would download the config an the snapshot and put it to my backup storage. And not create a new VM attach the disk and run a backup with backup programm. And for restoring do the sam way backwards. If i look at other project, there seems do be a way to download the snapshot and configfile, or am I wrong? Maybe someone can explain to me why I should use additional software to install in an additional machine. Or even better someone can explain to me how I don't have to use additional backup software. And to the same topic backup. There is in the documentation the possibility to set up a backup storage It is nearly the same, create a snapshot, or clone the machine and export it to backup storage > Export the new virtual machine to a backup domain. See Exporting a Virtual Machine to a Data Domain in the Virtual Machine Management Guide. Sadly there is just writen what to do, not how, the link points to 404 page. maybe someone can explain to me how to use backup storage thank you very much shb
