Re: Problems with setting up ovirt 4.4 for incremental backups

Hi Lukasz, Thank you for testing the new Incrementa backup feature. For those kinds of questions, it is better to send the mail to +users <users(a)ovirt.org> list so other people can learn/answer the question. Please see my comments inline.

There is a backups service that you can find under - GET path-to-engine/ovirt-engine/api/vms/vm-uuid/backups To get a single backup you can use GET path-to-engine/ovirt-engine/api/vms/vm-uuid/backups/backup-uuid We are now working on exposing also the checkpoints service to allow removal of checkpoints, but this isn't ready yet. > 4.

oVirt-node 4.4.0 - Hosted engine deployment fails when host is unable to download updates
by Marco Fais 04 Jul '20

04 Jul '20

Hi, fresh installation of oVirt-node 4.4.0 on a cluster -- the hosted-engine --deploy command fails if DNF is unable to download updates. This cluster is not connected to the public network at the moment. If I use a proxy (setting the relevant env. variables) it fails at a later stage (I think the engine VM is trying to download updates as well, but encounters the same issue and doesn't seem to use the proxy). With oVirt-node 4.3.x I didn't have this issue -- any suggestions? [~]# hosted-engine --deploy [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup During customization use CTRL-D to abort. Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine. The locally running engine will be used to configure a new storage domain and create a VM there. At the end the disk of the local VM will be moved to the shared storage. Are you sure you want to continue? (Yes, No)[Yes]: Configuration files: Log file: /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20200604214638-vae2wf.log Version: otopi-1.9.1 (otopi-1.9.1-1.el8) [ INFO ] DNF Downloading 1 files, 0.00KB [ INFO ] DNF Downloaded Extra Packages for Enterprise Linux 8 - x86_64 [ * ERROR ] DNF Failed to download metadata for repo 'ovirt-4.4-epel'[ ERROR ] DNF Failed to download metadata for repo 'ovirt-4.4-epel'[ ERROR ] Failed to execute stage 'Environment setup': Failed to download metadata for repo 'ovirt-4.4-epel'* [ INFO ] Stage: Clean up [...] Thanks, Marco

New fenceType in oVirt code for IBM OpenBMC
by Vinícius Ferrão 04 Jul '20

04 Jul '20

Hello, After some days scratching my head I found that oVirt is probably missing fenceTypes for IBM’s implementation of OpenBMC in the Power Management section. The host machine is an OpenPOWER AC922 (ppc64le). The BMC basically is an “ipmilan” device but the ciphers must be defined as 3 or 17 by default: [root@h01 ~]# ipmitool -I lanplus -H 10.20.10.2 root -P 0penBmc -L operator -C 3 channel getciphers ipmi ID IANA Auth Alg Integrity Alg Confidentiality Alg 3 N/A hmac_sha1 hmac_sha1_96 aes_cbc_128 17 N/A hmac_sha256 sha256_128 aes_cbc_128 The default ipmilan connector forces the option cipher=1 which breaks the communication. So I was reading the code and found this “fenceType” class, but I wasn't able to found where to define those classes. So I can create another one called something like openbmc to set cipher=17 by default. Another question is how bad the output is, it only returns a JSON-RPC generic error. But I don’t know how to suggest a fix for this. Thanks,

Re: broker.log not rotating
by Darrell Budic 03 Jul '20

They’re just log files, so generally safe to delete. You may want to take a look at the huge one though, see what’s up. I had a similar problem that turned out to be a broken HA agent install, cleaned and reinstalled and it went back to the same volume of logs as the others. Now I need to check if they added logrotate.d config files for it to clean those up, hum. -Darrell > On Jul 2, 2020, at 12:00 AM, Anton Louw via Users <users(a)ovirt.org> wrote: > > > > Hi All, > > I had a space alert on one of my nodes this morning, and when I looked around, I saw that var/log/ovirt-hosted-engine-ha/broker.log was sitting at around 30GB.

I would recommend you to try to logrotate it. I had similar issue with corrupted logrotate state file which led to vdsm growing to 20GB You can also use 'truncate -s 0 your.log' to wipe without removing it.

broker.log not rotating
by Anton Louw 02 Jul '20

02 Jul '20

Hi All, I had a space alert on one of my nodes this morning, and when I looked around, I saw that var/log/ovirt-hosted-engine-ha/broker.log was sitting at around 30GB. Does anybody know if it is safe to delete the log file? Or is there another process that I should follow? I had a look at my other nodes, and the broker.log file does not exceed 4GB. Thank you Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

VMs shutdown mysteriously
by Bobby 01 Jul '20

01 Jul '20

Hello, All 4 VMs on one of my oVirt cluster node shutdown for an unknown reason almost simultaneously. Please help me to find the root cause. Thanks. Please note the host seems doing fine and never crash or hangs and I can migrate VMs back to it later. Here is the exact timeline of all the related events combined from the host and the VM(s): On oVirt host: /var/log/vdsm/vdsm.log: 2020-06-25 15:25:16,944-0500 WARN (qgapoller/3) [virt.periodic.VmDispatcher] could not run <function <lambda> at 0x7f4ed2f9f5f0> on ['e0257b06-28fd-4d41-83a9-adf1904d3622'] (periodic:289) 2020-06-25 15:25:19,203-0500 WARN (libvirt/events) [root] File: /var/lib/libvirt/qemu/channels/e0257b06-28fd-4d41-83a9-adf1904d3622.ovirt-guest-agent.0 already removed (fileutils:54) 2020-06-25 15:25:19,203-0500 WARN (libvirt/events) [root] File: /var/lib/libvirt/qemu/channels/e0257b06-28fd-4d41-83a9-adf1904d3622.org.qemu.guest_agent.0 already removed (fileutils:54) [root@athos log]# journalctl -u NetworkManager --since=today -- Logs begin at Wed 2020-05-20 22:07:33 CDT, end at Thu 2020-06-25 16:36:05 CDT. -- Jun 25 15:25:18 athos NetworkManager[1600]: <info> [1593116718.1136] device (vnet0): state change: disconnected -> unmanaged (reason 'unmanaged', sys-iface-state: 'removed') Jun 25 15:25:18 athos NetworkManager[1600]: <info> [1593116718.1146] device (vnet0): released from master device SRV-VL /var/log/messages: Jun 25 15:25:18 athos kernel: SRV-VL: port 2(vnet0) entered disabled state Jun 25 15:25:18 athos NetworkManager[1600]: <info> [1593116718.1136] device (vnet0): state change: disconnected -> unmanaged (reason 'unmanaged', sys-iface-state: 'removed') Jun 25 15:25:18 athos NetworkManager[1600]: <info> [1593116718.1146] device (vnet0): released from master device SRV-VL Jun 25 15:25:18 athos libvirtd: 2020-06-25 20:25:18.122+0000: 2713: error : qemuMonitorIO:718 : internal error: End of file from qemu monitor /var/log/libvirt/qemu/aries.log: 2020-06-25T20:25:28.353975Z qemu-kvm: terminating on signal 15 from pid 2713 (/usr/sbin/libvirtd) 2020-06-25 20:25:28.584+0000: shutting down, reason=shutdown ============================================================================================= On the first VM effected (same thing on others): /var/log/ovirt-guest-agent/ovirt-guest-agent.log: MainThread::INFO::2020-06-25 15:25:20,270::ovirt-guest-agent::104::root::Stopping oVirt guest agent CredServer::INFO::2020-06-25 15:25:20,626::CredServer::262::root::CredServer has stopped.

Hi Anton, to diagnose the issue we would need to have logs from both engine and affected host.
