Host reboots when network switch goes down
by cen 29 Sep '21

29 Sep '21

Hi, we are experiencing a weird issue with our Ovirt setup. We have two physical hosts (DC1 and DC2) and mounted Lenovo NAS storage for all VM data. They are connected via a managed network switch. What happens is that if switch goes down for whatever reason (firmware update etc), physical host reboots. Not sure if this is an action performed by Ovirt but I suspect it is because connection to mounted storage is lost and it performs some kind of an emergency action. I would need to get some direction pointers to find out a) who triggers the reboot and why c) a way to prevent reboots by increasing storage? timeouts Switch reboot takes 2-3 minutes. These are the host /var/log/messages just before reboot occurs: Sep 28 16:20:00 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:00 7690984 [10993]: s11 check_our_lease warning 72 last_success 7690912 Sep 28 16:20:00 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:00 7690984 [10993]: s3 check_our_lease warning 76 last_success 7690908 Sep 28 16:20:00 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:00 7690984 [10993]: s1 check_our_lease warning 68 last_success 7690916 Sep 28 16:20:00 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:00 7690984 [27983]: s11 delta_renew read timeout 10 sec offset 0 /var/run/vdsm/storage/15514c65-5d45-4ba7-bcd4-cc772351c940/fce598a8-11c3-44f9-8aaf-8712c96e00ce/65413499-6970-4a4c-af04-609ef78891a2 Sep 28 16:20:00 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:00 7690984 [27983]: s11 renewal error -202 delta_length 20 last_success 7690912 Sep 28 16:20:00 ovirtnode02 wdmd[11102]: test warning now 7690984 ping 7690970 close 7690980 renewal 7690912 expire 7690992 client 10993 sanlock_hosted-engine:2 Sep 28 16:20:00 ovirtnode02 wdmd[11102]: test warning now 7690984 ping 7690970 close 7690980 renewal 7690908 expire 7690988 client 10993 sanlock_3cb12f04-5d68-4d79-8663-f33c0655baa6:2 Sep 28 16:20:01 ovirtnode02 systemd: Created slice User Slice of root.

Ovirt 4.3 Upload of Image fails
by Mark Morgan 29 Sep '21

29 Sep '21

Hi, I am trying to upload an image to a Ovirt 4.3 Instance but it keeps failing. After a few seconds it says paused by system. The test connection is successful in the upload image window so we have installed the certificate properly. Due to an older thread(https://www.mail-archive.com/users@ovirt.org/msg50954.html) I also checked if it has something to do with wifi. But I am not even using a wifi connection. Here is a small part of the log, where you can see the transfer failing. 2021-09-29 11:44:43,011+02 INFO [org.ovirt.engine.core.bll.storage.disk.image.TransferImageStatusCommand] (default task-96804) [d370a18b-bb12-4992-9fc8-7ce6607358f8] Running command: TransferImageStatusCommand internal: false.

Failed to update OVF disks / Failed to update VMs/Templates OVF data for Storage Domain
by nicolas＠devels.es 29 Sep '21

29 Sep '21

Hi, We upgraded from oVirt 4.3.8 to 4.4.8 and sometimes we're finding events like these in the event log (3-4 times/day): Failed to update OVF disks 77818843-f72e-4d40-9354-4e1231da341f, OVF data isn't updated on those OVF stores (Data Center KVMRojo, Storage Domain pv04-003). Failed to update VMs/Templates OVF data for Storage Domain pv02-002 in Data Center KVMRojo. I found [1], however, it seems not to solve the issue. I restarted all the hosts and we're still getting the messages. We couldn't upgrade hosts to 4.4 yet, FWIW. Maybe it's caused by this? If someone could shed some light about this, I'd be grateful. Thanks. [1]: https://access.redhat.com/solutions/3353011

Managed Block Storage and Templates
by Shantur Rathore 28 Sep '21

28 Sep '21

Hi all, Anyone tried using Templates with Managed Block Storage? I created a VM on MBS and then took a snapshot. This worked but as soon as I created a Template from snapshot, the template got created but there is no disk attached to the template. Anyone seeing something similar? Thanks

Managed Block Storage issues
by Shantur Rathore 28 Sep '21

28 Sep '21

Hi all, I am trying to set up Managed block storage and have the following issues. My setup: Latest oVirt Node NG : 4.4.8 Latest oVirt Engine : 4.4.8 1. Unable to copy to iSCSI based block storage I created a MBS with Synology UC3200 as a backend ( supported by Cinderlib ). It was created fine but when I try to copy disks to it, it fails. Upon looking at the logs from SPM, I found "qemu-img" failed with an error that it cannot open "/dev/mapper/xxxxxxxxxx" : Permission Error. Had a look through the code and digging out more, I saw that a. Sometimes /dev/mapper/xxxx symlink isn't created ( log attached ) b. The ownership to /dev/mapper/xxxxxx and /dev/dm-xx for the new device always stays at root:root I added a udev rule ACTION=="add|change", ENV{DM_UUID}=="mpath-*", GROUP="qemu", OWNER="vdsm", MODE="0660" and the disk copied correctly when /dev/mapper/xxxxx got created. 2. Copy progress finishes in UI very early than the actual qemu-img process. The UI shows the Copy process is completed successfully but it's actually still copying the image. This happens both for ceph and iscsi based mbs. Is there any known workaround to get iSCSI MBS working? Kind regards, Shantur

I have 4 servers of identical hardware. The documentation says "you need 3", not "you need 3 or more"; is it possible to run hyperconverged with 4 servers. Currently all the 4 nodes server has been crashed n after the 4th node try joining the hyperconverged 3nodes cluster. Kindly advise. FYI currently i'm trying to reinstall back all the OS back due mentioned incident happen. /BR Faizal

Hi Diggy, If you have updated to oVirt 4.4.8 prior to 4.4.8.6 async release, it means your system got impacted. To fix it, you need to set some value to HEVM timezone and then try again (at least how I understand it). Regards, Marina.

about the Live Storage Migration
by Tommy Sway 27 Sep '21

27 Sep '21

From the document: Overview of Live Storage Migration Virtual disks can be migrated from one storage domain to another while the virtual machine to which they are attached is running. This is referred to as live storage migration. When a disk attached to a running virtual machine is migrated, a snapshot of that disk's image chain is created in the source storage domain, and the entire image chain is replicated in the destination storage domain. As such, ensure that you have sufficient storage space in both the source storage domain and the destination storage domain to host both the disk image chain and the snapshot. A new snapshot is created on each live storage migration attempt, even when the migration fails. Consider the following when using live storage migration: You can live migrate multiple disks at one time. Multiple disks for the same virtual machine can reside across more than one storage domain, but the image chain for each disk must reside on a single storage domain. You can live migrate disks between any two storage domains in the same data center. You cannot live migrate direct LUN hard disk images or disks marked as shareable. But where do users perform online storage migrations? There seems to be no interface.

Re: About the vm memory limit
by Tommy Sway 27 Sep '21

In fact, I am very interested in the part you mentioned, because my environment is running relational database, which usually requires a large amount of memory, and some systems clearly need to configure HUGEPAGE memory (such as Oracle). Could you elaborate on some technical details about the management of huge page memory? And the difference between 4.3 and 4.4 in this respect? Thank you very much!

If you have 256G per CPU, it's best to stay into that range. Also, consider disabling transparent huge pages on the host & VM. Since 4.4 Regular Huge Pages (do not confuse them with THP) can be used on the Hypervisors, while on 4.3 there were some issues but I can't provode any details.

For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed. I want to know what is the best use of memory for a virtual machine, since the virtual machine is just a QEMU emulation process on a physical machine, and I worry that it is not using as much memory as a physical machine.
