CPU usage question
by David Johnson 28 May '21

28 May '21

Hi everyone, I am slowly working the performance bottlenecks out of my rack, and ran into this puzzling scenario. Ovirt shows CPU usage at over 50%. Windows shows CPU usage between 5 and 15 % The backing store is TrueNAS NFS on a 10 GBit lan. I am seeing just under 1 GBit throughput on the storage network for this operation (create database). Am I reading this correctly that my system is bottlenecking on the CPU used to handle the Windows disk IO over TCP/IP ? Thanks *David Johnson* Screenshot of pertinent metrics: [image: image.png] <https://www.linkedin.com/in/pojoguy/> <https://maxistechnology.com/wp-content/uploads/vcards/vcard-David_Johnson.v…> <https://maxistechnology.com/> *Follow us:* <https://www.linkedin.com/company/maxis-tech-inc/>

Unable to migrate VMs
by Jayme 27 May '21

27 May '21

I have a three node oVirt 4.4.5 cluster running oVirt node hosts. Storage is mix of GlusterFS and NFS. Everything has been running smoothly, but the other day I noticed many VMs had invalid snapshots. I run a script to export OVA for VMs for backup purposes, exports seemed to have been fine but snapshots failed to delete at the end. I was able to manually delete the snapshots through oVirt admin GUI without any errors/warnings and the VMs have been running fine and can restart them without problems. I thought this problem may be due to snapshot bug which is supposedly fixed in oVirt 4.4.6. I decided to start upgrading cluster to 4.4.6 and am now having a problem with VMs not being able to migrate. When I migrate any VM (doesn't seem to matter which host to and from) the process starts but stops at 0-1%. Eventually after 15-30 minutes or more the tasks are all completed by the VM is not migrated. I am unable to migrate any VMs and as such I cannot place any host in maintenance mode. I've attaching some VDSM logs from source and destination hosts, these were after initiating a migration of a single VM I'm seeing some errors in the logs regarding the migration stalling, but not able to determine why its stalling. 2021-05-27 17:10:22,167+0000 INFO (jsonrpc/4) [api.host] FINISH getAllVmIoTunePolicies return={'status': {'code': 0, 'message': 'Done'}, 'io_tune_policies_dict': {'f8f4e4a1-b565-4663-8962-c8804dbb86fb': {'policy': [], 'current_values': [{'name': 'vda', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme1n1/bce04425-1d25-4489-bdab-2834a1a57db8/images/38b27cce-c744-4a12-85a3-3af07d386da2/93c1e793-f8cb-42c9-86a6-0e9ce4a6023a', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}, '2b87204f-f695-474a-9f08-47b85fcac366': {'policy': [], 'current_values': [{'name': 'sda', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme0n1/a99cd663-f6d5-42d8-bd7a-ee0b5d068608/images/f2e0c9f3-ab0d-441a-85a6-07a42e78b5a8/848f353e-6787-4e20-ab7b-0541ebd852c6', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}, '26332421-54a3-4afc-90e7-551a7e314c80': {'policy': [], 'current_values': [{'name': 'vda', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme0n1/a99cd663-f6d5-42d8-bd7a-ee0b5d068608/images/b7a785f9-307b-42af-9bbe-23cac884fe97/ed1d027e-a36a-4e6b-9207-119915044e06', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}, '60edbd80-dad7-4bf8-8fd1-e138413cf9f6': {'policy': [], 'current_values': [{'name': 'sda', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme2n1/a7efa448-201b-4453-9bc9-900559b891ca/images/535fcb2e-ece9-4d50-86fe-bf6264d11ae1/6c01a036-8a14-46ba-a4b4-fe4f66a586a3', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}, {'name': 'sdb', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme2n1/a7efa448-201b-4453-9bc9-900559b891ca/images/1f467fb5-5ea7-42ba-bace-f175c86791b2/cbe8327f-9b7f-442f-a650-6888bb11a674', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}, {'name': 'sdd', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme2n1/a7efa448-201b-4453-9bc9-900559b891ca/images/c93956d5-c88d-41f9-8c38-9f5f62cc90dd/3920b46c-5fab-4b63-b47f-2fa5c6714c36', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}, 'beeefe06-78a0-4e14-a932-cc8d734d542d': {'policy': [], 'current_values': [{'name': 'sda', 'path': '/rhev/data-center/mnt/glusterSD/gluster0.grove.silverorange.com:_data__sdb/30fd0a2f-ab42-4a8a-8f0b-67242dc2d15d/images/310d8b3e-d578-418d-9802-dc0ebcea06d6/aa758c51-8478-4273-aeef-d4b374b8d6b4', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}, {'name': 'sdb', 'path': '/rhev/data-center/mnt/glusterSD/gluster0.grove.silverorange.com:_data__sdb/30fd0a2f-ab42-4a8a-8f0b-67242dc2d15d/images/4072fda1-ec82-45c9-b353-91fceb13bf08/891f5982-dead-48b4-8907-caa1e309fa82', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}, '7e5156de-649d-4904-9092-21a699242a37': {'policy': [], 'current_values': [{'name': 'vda', 'path': '/rhev/data-center/mnt/10.11.0.9:_vmstorage_nvme0n1/a99cd663-f6d5-42d8-bd7a-ee0b5d068608/images/ca0c1208-a7aa-4ef6-a450-4a40bd4455f3/a2335199-ddd4-429b-b55d-f4d527081fd3', 'ioTune': {'total_bytes_sec': 0, 'read_bytes_sec': 0, 'write_bytes_sec': 0, 'total_iops_sec': 0, 'write_iops_sec': 0, 'read_iops_sec': 0}}]}}} from=::1,35012 (api:54) 2021-05-27 17:10:31,118+0000 WARN (migmon/7e5156de) [virt.vm] (vmId='7e5156de-649d-4904-9092-21a699242a37') Migration stalling: remaining (32863MiB) > lowmark (32863MiB).

Ovirt 4.4.6.8-1 upload ova as template to multiple hosts
by Don Dupuis 27 May '21

27 May '21

I have a single ovirt manager and 2 ovirt hosts, each has a local storage domain. I am using the upload_ova_as_template.py and my template upload works on a single host but not both. If I use the gui method, there is the option of "clone" and putting in a new name for the template. This seems to work most of the time, but it has failed a couple of times also. I would like to add the same "clone" and "name" option to the upload_ova_as_temple.py. What is the best way to do this since I need to have unique UUIDs for the template disks? This is a unique setup in the fact that I can't use shared storage and this should be doable as I was able to do it in the ovirt gui. Thanks Don

what does dwh db contain?
by Nathanaël Blanchet 27 May '21

27 May '21

Hello, I need to understand which user removed a vm 2 months ago, but I can't recover such info into engine.log (that default rotate is 20). I gave a quick look to the dwh database: I'm able to find the removal date, but not the associated user. Is there a way to get this information? -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Re: CPU Compatibility Problem after Upgrading Centos 8 Stream Host

If it's the same problem that I ran into then it's the latest version of edk2-ovmf. I'm not sure why it was pushed into the repos without a fixed libvirt to go with it.

Live ("any") disk migration between storages KILLS a virtual machine with Windows (UEFI) !!!
by Patrick Lomakin 27 May '21

27 May '21

The weekend went horribly. I created a second storage domain in order to move all the virtual machines to a higher performance RAID array (From RAID6 to RAID10). My mistake was trying to move two Windows domain controllers from one storage domain to another. The problem is that when I "live" moved the virtual machine disk between storage domains, my Windows Server 2019 virtual machines worked fine until the next reboot. After a reboot, the machine just won't start and throws an error - Status: 0xc0000428 - The digital signature for this file couldn't be verified. Moving back to the "old" domain doesn't help. None of the procedures with VMs worked (Re-create boot area, turn on kernel flag - bcdedit.exe /set nointegritychecks on). I am ready to help and interested in developing Ovirt. I can also provide more information to developers if needed.

Re: CPU Compatibility Problem after Upgrading Centos 8 Stream Host
by k.gunasekhar＠non.keysight.com 27 May '21

I also end up with the same problem today. How did rollback yum i see many yum updates in the yum history. Here is what the error says. The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: model_IvyBridge, spec_ctrl. Please update the host CPU microcode or change the Cluster CPU Type.

Adding a 4th compute host to a HCI environment
by David White 27 May '21

27 May '21

Hello, Is there documentation anywhere for adding a 4th compute-only host to an existing HCI cluster? I did the following earlier today: - Installed RHEL 8.4 onto the new (4th) host - Setup an NFS share on the host - Attached the NFS share to oVirt as a new storage domain - I then turned the NFS share into a "backup domain" - Once that was done, I installed ovirt-release44.rpm, followed by some ovirt packages: - yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm - yum install cockpit-ovirt-dashboard vdsm-gluster ovirt-host - I then logged into the oVirt Manager Web UI, navigated to Hosts, and clicked on New - I successfully added the new host to the cluster Once this was all done, load average on all 3 of my original HCI nodes started to go through the roof. I've seen servers' load average go through the roof before when NFS shares are down, so I suspect that something happened to the NFS share when I went to add the host as a compute node. In an effort to get things stabilized, I wound up yanking the new host out of oVirt, as well as the NFS share, at which point things did stabilize again. My goal here: - Setup the host as a compute-only host (don't participate in the gluster cluster) - Setup the NFS share for backup purposes Writing this email and reviewing my bash history, I think one of the places I went wrong was I installed vdsm-gluster. I don't think I need that, do I? Is what I'm trying to do possible? Sent with ProtonMail Secure Email.

Guest CPU compatibility issues on upgraded host - RHEL 8
by David White 27 May '21

27 May '21

I have oVirt 4.4.6 running on my Engine VM. I also have oVirt 4.4.6 on one of my hosts. The other two hosts are still on oVirt 4.4.5. My issue seems slightly different than the issue(s) other people have described. I'm on RHEL 8 hosts. My Engine VM is running fine on the upgraded host, as is one of my Ubuntu guests. However, it seems like I'm not able to migrate *ANY* other guests over the new host. The oVirt UI just indicates that for whatever reason the upgraded host isn't available / compatible for a VM to be migrated to. I'm not sure how or why this 1 Ubuntu guest VM was able to get migrated, but it looks like its working just fine. I did try: yum downgrade edk2-ovmf Base on other people's comments. But I'm not sure how long to wait, or what else to try, to try to get my upgraded host operational again. Sent with ProtonMail Secure Email.
