ovirt terraform - multiple nics creation problem
by marek 13 Jul '20

13 Jul '20

i have problem with creation VM with multiple nics part of terraform config resource "ovirt_vm" "vm" { .... initialization { authorized_ssh_key = "${var.vm_authorized_ssh_key}" host_name = "${var.vm_hostname}" timezone = "${var.vm_timezone}" user_name = "${var.vm_user_name}" custom_script = "${var.vm_custom_script}" dns_search = "${var.vm_dns_search}" dns_servers = "${var.vm_dns_servers}" nic_configuration { label = "eth0" boot_proto = "${var.vm_nic_boot_proto}" address = "${var.vm_nic_ip_address}" gateway = "${var.vm_nic_gateway}" netmask = "${var.vm_nic_netmask}" on_boot = "${var.vm_nic_on_boot}" } nic_configuration { label = "eth1" boot_proto = "${var.vm_nic2_boot_proto}" address = "${var.vm_nic2_ip_address}" gateway = "${var.vm_nic2_gateway}" netmask = "${var.vm_nic2_netmask}" on_boot = "${var.vm_nic2_on_boot}" } } } resource "ovirt_vnic" "eth0" { name = "eth0" vm_id = "${ovirt_vm.vm.id}" vnic_profile_id = "${data.ovirt_vnic_profiles.nic1.vnic_profiles.0.id}" } resource "ovirt_vnic" "eth1" { name = "eth1" vm_id = "${ovirt_vm.vm.id}" vnic_profile_id = "${data.ovirt_vnic_profiles.nic2.vnic_profiles.0.id}" } how terraform knows which nic_configuration {} from ovirt_vm belongs to which resource "ovirt_vnic"? my problem is that VM has paired nic_configuration(eth0) with resource "ovirt_vnic" "eth1" and vice versa any hints? https://github.com/oVirt/terraform-provider-ovirt/blob/master/ovirt/resourc… my experience with Go is not enough to understand how is "pairing" done Marek

Revert to 4.3
by jb 13 Jul '20

13 Jul '20

Hello everybody, at to moment I run ovirt engine in a VM on a different server (no hosted engine) and I have two hosts. One is only a backup and is not running. I would like to install a new ovirt engine 4.4 VM and use the backup host. And if this is running fine in some month I would migrate the second host to 4.4. The Problem is only that I have to upgrade the data center compatibly mode to 4.4 and with that I'm a bit afraid. Is it possible, to downgrade the compatibility mode, when something unsuspected is happen? The original 4.3 engine VM I would like to have untouched, that I can go back if is necessary. Regards Jonathan

Not able to asign IB network to IB Bond
by Andrey Rusakov 12 Jul '20

12 Jul '20

Hi all, We are using oBirt since 4.2. Config is 1Gb or 10G for VM ext network and 40Gb IB for Starage and VM Migration. We are testing 4.4 and 4.4.0 at the moment. 2 problems - Major problem is that i can't assign IB netwrok to IB bond i got - "Error while executing action HostSetupNetworks: Unexpected exception" VDSM.log 2020-07-11 15:33:39,147+0300 INFO (jsonrpc/1) [api.network] START setupNetworks(networks={'IB': {'netmask': '255.255.255.0', 'bonding': 'bond1', 'ipv6autoconf': False, 'bridged': 'false', 'ipaddr': '172.17.21.101', 'dhcpv6': False, 'mtu': 65520, 'switch': 'legacy'}}, bondings={}, options={'connectivityTimeout': 120, 'commitOnSuccess': True, 'connectivityCheck': 'true'}) from=::ffff:172.16.21.201,33614, flow_id=fe589281-3171-41b4-b7aa-e28a4bbebe55 (api:48) 2020-07-11 15:33:40,088+0300 INFO (jsonrpc/1) [api.network] FINISH setupNetworks error=MAC address cannot be specified in bond interface along with specified bond options from=::ffff:172.16.21.201,33614, flow_id=fe589281-3171-41b4-b7aa-e28a4bbebe55 (api:52) 2020-07-11 15:33:40,088+0300 ERROR (jsonrpc/1) [jsonrpc.JsonRpcServer] Internal server error (__init__:350) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/yajsonrpc/__init__.py", line 345, in _handle_request res = method(**params) File "/usr/lib/python3.6/site-packages/vdsm/rpc/Bridge.py", line 198, in _dynamicMethod result = fn(*methodArgs) File "<decorator-gen-480>", line 2, in setupNetworks File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 1548, in setupNetworks supervdsm.getProxy().setupNetworks(networks, bondings, options) File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 56, in __call__ return callMethod() File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 54, in <lambda> **kwargs) File "<string>", line 2, in setupNetworks File "/usr/lib64/python3.6/multiprocessing/managers.py", line 772, in _callmethod raise convert_to_error(kind, result) libnmstate.error.NmstateValueError: MAC address cannot be specified in bond interface along with specified bond options 2nd problem - IB bond not working after reboot - theres is no bond1 insterface at all (my solution is to restart network) This is not very important as VDSM will change config after Adding bond to oVirt. P.S. I Got 100% same config with same cards and samу bond config on 4.3 - everething is wotking fine.

Metrics in Kibana not working
by Guillaume Pavese 12 Jul '20

12 Jul '20

Trying to use the provided visualizations/Dashboards for ovirt metrics in Kibana. Using ovirt 4.3.7, with ovirt-engine-metrics 1.3.7-1 and latest rsylog-8.24.0-52 and collectd-5.10.0-2 I am receiving data in indexes and some fields are present. A few graph work, but most don't and I am getting a lot of errors like theses : Error in visualisation[esaggs] > "field" is a required parameter - On my hosts I can see the following collectd errors: systemd[1]: Starting Collectd statistics daemon... collectd[21629]: plugin_load: plugin "disk" successfully loaded. ... collectd[21629]: plugin_load: plugin "network" successfully loaded. collectd[21629]: Systemd detected, trying to signal readiness. systemd[1]: Started Collectd statistics daemon. collectd[21629]: virt plugin: reader virt-0 initialized collectd[21629]: Initialization complete, entering read-loop. collectd[21629]: write_syslog plugin: send failed with status -1 (Connection reset by peer) collectd[21629]: write_syslog plugin: error with ws_send_message - And the following rsyslog ones : systemd[1]: Starting System Logging Service... rsyslogd[210059]: [origin software="rsyslogd" swVersion="8.24.0-52.el7_8.2" x-pid="210059" x-info="http://www.rsyslog.com"] start systemd[1]: Started System Logging Service. rsyslogd[210059]: command 'SystemLogSocketName' is currently not permitted - did you already set it via a RainerScript command (v6+ config)?

Please reopen if you can provide needed info." Is my understanding correct that only RedHat employees can reopen closed bugs? I have encountered quite a lot of situations where I'm facing an issue covered by such a closed bug with a "please reopen if you can provide info" msg, but frustratingly not being able to do so...

Is there a way to access VM data that is stored using iscsi block storage outside of the ovirt platform ?
by Kevin Doyle 10 Jul '20

10 Jul '20

We have had problems trying to get our broken hosted engine to work. The datastore for all the VM's was stored in an iscsi storage that was deactivated before the platform went down, I am now looking for a way to access this data and start the VM's outside of a running hosted-engine Can I build an new ovirt standalone engine on a new bare metal remote server and connect to the hosts and start up the domain ? I would be interested in your thoughts. The problem with rebuilding the hosted-engine is that it cannot reuse the lun dedicated for the hosted-engine. I have tried to rebuild using NFS but it complains about not seeing the master domain thanks Kevin

Weird problem starting VMs in oVirt-4.4
by Joop 10 Jul '20

10 Jul '20

Hi All, Just had a rather new experience in that starting a VM worked but the kernel entered grub2 rescue console due to the fact that something was wrong with its virtio-scsi disk. The message is Booting from Hard Disk .... error: ../../grub-core/kern/dl.c:266:invalid arch-independent ELF maginc. entering rescue mode... Doing a CTRL-ALT-Del through the spice console let the VM boot correctly. Shutting it down and repeating the procedure I get a disk problem everytime. Weird thing is if I activate the BootMenu and then straight away start the VM all is OK. I don't see any ERROR messages in either vdsm.log, engine.log If I would have to guess it looks like the disk image isn't connected yet when the VM boots but thats weird isn't it? Regards, Joop

Problem with backuping ovirt 4.4 with SDK
by Łukasz Kołaciński 09 Jul '20

09 Jul '20

Hello, I am trying to do full backup on ovirt 4.4 using sdk. I used steps from this youtube video: https://www.youtube.com/watch?v=E2VWUVcycj4 and I got error after running backup_vm.py. I see that sdk has imported disks and created backup entity and then I got sdk.NotFoundError exception.

oVirt 4.3 -> 4.4 Upgrade Path Questions
by Andrei Verovski 08 Jul '20

08 Jul '20

Hi ! I have 2-node oVirt 4.3 installation, with engine running as KVM guest on SuSE file server (not hosted engine). Nodes are manually installed on CentOS 7.x (further referred as old node #1 and #2). I’m going to add 1 additional node, and migrate system to CentOS 8.2 / oVirt 4.4. Is this correct roadmap, or something can be done in a better way? Here is my plan. 1) Upgrade oVirt Hosted Engine running under KVM / SuSE file server to CentOS 8.2 / oVirt 4.4. Or its better to install from scratch new CentOS 8.2/oVirt 4.4 and migrate database? 2) Install CentOS 8.2 and oVirt node 4.4 on new server (let’s name it node #3). 3) Migrate virtual machines from old node #1 to the new (#3). 4) Upgrade CentOS on old node #1 to v8.2, and oVirt from web interface. Will that work, or upgrade CentOS 7 -> 8 will render this process unmanageable due to removal of many components? 5) Migrate back virtual machines from node #3 to newly upgraded node #1. 6) Repeat step 4 and 5 for old node #2. I have set of custom shell and python scripts running on engine and nodes, so manual installation was a way to go. Thanks in advance for any suggestion(s) with best regards Andrei

[ANN] oVirt 4.4.1 is now generally available
by Lev Veyde 08 Jul '20

08 Jul '20

oVirt 4.4.1 is now generally available The oVirt project is excited to announce the general availability of oVirt 4.4.1 , as of July 8th, 2020. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. What’s new in oVirt 4.4.1 Release? This update is the first in a series of stabilization updates to the 4.4 series. This release introduces a new monitoring solution that provides a user interface to oVirt DWH collected data using Grafana. This allows admins to track inventory, monitor performance and capacity trends, and easily identify and troubleshoot resources issues. Grafana is installed and configured during engine-setup and includes pre-built dashboards that are based on the data collected by the ovirt_engine_history PostgreSQL Data Warehouse database (BZ#1777877 <https://bugzilla.redhat.com/show_bug.cgi?id=1777877>). In oVirt 4.4.1 the maximum memory size for 64-bit x86_64 and ppc64/ppc64le VMs is now 6TB. For x86_64 this limit is applied also to VMs in 4.2 and 4.3 Cluster Levels. You can now use CentOS Stream as an alternative to CentOS Linux on non-production systems. This release is available now on x86_64 architecture for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) - oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) oVirt Node and Appliance have been updated, including: - oVirt 4.4.1: http://www.ovirt.org/release/4.4.1/ - CentOS Linux 8.2.2004: https://lists.centos.org/pipermail/centos-announce/2020-June/035756.html - CentOS Virt SIG updates including Advanced Virtualization 8.2 (qemu-kvm 4.2 <https://www.qemu.org/2019/12/13/qemu-4-2-0/>, libvirt 6.0.0 <https://libvirt.org/news.html#v6-0-0-2020-01-15>) - Wildfly 19.1.0: https://wildfly.org/news/2020/05/04/WildFly-1910-Released/ - Ansible 2.9.10: https://github.com/ansible/ansible/blob/stable-2.9/changelogs/CHANGELOG-v2.… - Glusterfs 7.6: https://docs.gluster.org/en/latest/release-notes/7.6/ See the release notes [1] for installation instructions and a list of new features and bugs fixed.

rhv 4.3.9 - snapshots fail
by Markus Schaufler 08 Jul '20

08 Jul '20

Hi, I think we ran into this bug https://bugzilla.redhat.com/show_bug.cgi?id=1802277 and https://access.redhat.com/solutions/5174961 as we have exactly that problems and log-entries. As there are now several VMs that cannot create (or delete) snapshots accordingly we cannot do backups on that VMs. Are there any suggestions or workarounds in order that we can still backup them up? Thanks very much, Markus

Hosted engine can't start after changing cluster settings
by Patrick Lomakin 08 Jul '20

08 Jul '20

I changed the BIOS Type settings in the cluster settings section to UEFI BIOS, and hosted-engine does not start after rebooting. Although, before I made the changes, I looked in the engine at the /boot partition, which has the /efi directory. Is there any way to change the engine settings manually, and how can I connect to it (or to its partitions) to perform actions? I can't imagine how you can reinstall the engine without unplugging storage to import all virtual machines later. Losing data in virtual machines is a disaster for me.

Ovirt 4.3.10 Glusterfs SSD slow performance over 10GE
by jury cat 07 Jul '20

07 Jul '20

Hello all, I am using Ovirt 4.3.10 on Centos 7.8 with glusterfs 6.9 . My Gluster setup is of 3 hosts in replica 3 (2 hosts + 1 arbiter). All the 3 hosts are Dell R720 with Perc Raid Controller H710 mini(that has maximim throughtout 6Gbs) and with 2×1TB samsumg SSD in RAID 0. The volume is partitioned using LVM thin provision and formated XFS. The hosts have separate 10GE network cards for storage traffic. The Gluster Network is connected to this 10GE network cards and is mounted using Fuse Glusterfs(NFS is disabled).Also Migration Network is activated on the same storage network. The problem is that the 10GE network is not used at full potential by the Gluster. If i do live Migration of Vms i can see speeds of 7GB/s ~ 9GB/s. The same network tests using iperf3 reported 9.9GB/s , these exluding the network setup as a bottleneck(i will not paste all the iperf3 tests here for now). I did not enable all the Volume options from "Optimize for Virt Store", because of the bug that cant set volume cluster.granural-heal to enable(this was fixed in vdsm-4 40, but that is working only on Centos 8 with ovirt 4.4 ) . i whould be happy to know what are all these "Optimize for Virt Store" options, so i can set them manually. The speed on the disk inside the host using dd is b etween 1GB/s to 700Mbs. [root@host1 ~]# dd if=/dev/zero of=test bs=100M count=40 cou nt=80 status=progress 8074035200 bytes (8.1 GB) copied, 11.059372 s, 730 MB/s 80+0 records in 80+0 records out 8388608000 bytes (8.4 GB) copied, 11.9928 s, 699 MB/s The dd write test on the gluster volme inside the host is poor only ~ 120MB/s . During the dd test, if i look at Networks->Gluster network ->Hosts at Tx and Rx the network speed barerly reaches over 1Gbs (~1073 Mbs) out of maximum of 10000 Mbs. dd if=/dev/zero of=/rhev/data-center/mnt/glu sterSD/gluster1.domain.local\:_data/test bs=100M count=80 status=progress 8283750400 bytes (8.3 GB) copied, 71.297942 s, 116 MB/s 80+0 records in 80+0 records out 8388608000 bytes (8.4 GB) copied, 71.9545 s, 117 MB/s I have attached my Gluster volume settings and mount options. Thanks, Emy

Running Self Hosted-Engine on the same iSCSI target as other Storage Domains
by Erez Zarum 07 Jul '20

07 Jul '20

We are using Dell SC (Storage) with iSCSI with oVirt, it is impossible to create a new Target Portal with a specific LUN so it's impossible to isolate the SE LUN from other LUNs that are in use by other Storage Domains. According to the documentations this is not a best practice, while searching i ran into that specific issue but it seems to be solved. Is it still by best practice when using oVirt 4.4 to use a whole different target for the SE? If it is not possible giving the current envrionment restrictions is the only option for us is to attach a few disks to each servers and create a small gluster cluster (volume) just for the SE?

oVirt 4.4.0, slave interfaces are down after a reboot
by Erez Zarum 07 Jul '20

07 Jul '20

Fresh installation of oVirt 4.4.0 (using the ISO), after restarting an host, the host comes up but the slave interfaces of a bond remains in down state. The only way to bring it up is to login via IPMI and restart the "NetworkManager" service. Weird thing, after this, the host says that it's network is out of sync, this happens on a network that is marked as "migration network", what is out of sync is the gateway. I have restart the host again (this happens on all hosts) and i can see that after a restart the NetworkManager state (nmcli c show bond0.421 as example) does not list the routes, after syncing the routes are there.

iSCSI array "Storage domain does not exist" error after array reboot
by Kevin Doyle 07 Jul '20

07 Jul '20

I am running a hosted engine using iscsi. I had to reboot the array, I took down all the VM's and put the VM data storage into maintenance mode. I also put the hosted engine "hosted-engine --set-maintenance --mode =global" and shut down the engine "hosted-engine --vm-shutdown" I also stopped the broker and agent systemctl stop ovirt-ha-broker' ; 'systemctl stop ovirt-ha-agent' The array was rebooted. I started the broker and agent systemctl start ovirt-ha-broker' ; 'systemctl start ovirt-ha-agent' However I now see errors in the vdsm log INFO (jsonrpc/4) [storage.TaskManager.Task] (Task='76547cc5-e4f0-454c-ac46-c341e7f6d54c') aborting: Task is aborted: "Storage domain does not exist: (u'5626eba7-ebd8-4578-baf0-ca4f4af5889b',)" - code 358 (task:1181) 2020-07-07 14:01:25,098+0100 ERROR (jsonrpc/4) [storage.Dispatcher] FINISH prepareImage error=Storage domain does not exist: (u'5626eba7-ebd8-4578-baf0-ca4f4af5889b',) (dispatcher:83) 2020-07-07 14:01:25,098+0100 INFO (jsonrpc/4) [jsonrpc.JsonRpcServer] RPC call Image.prepare failed (error 358) in 0.07 seconds (__init__:312) INFO (vmrecovery) [vdsm.api] START getConnectedStoragePoolsList(options=None) from=internal, task_id=93d7e2d6-17ee-4370-b8c4-fb32a3887021 (api:48) 2020-07-07 14:01:25,592+0100 INFO (vmrecovery) [vdsm.api] FINISH getConnectedStoragePoolsList return={'poollist': []} from=internal, task_id=93d7e2d6-17ee-4370-b8c4-fb32a3887021 (api:54) 2020-07-07 14:01:25,592+0100 INFO (vmrecovery) [vds] recovery: waiting for storage pool to go up (clientIF:709) I have 6 hosts.

How to use sysprep to create Windows templates
by wodel youchi 07 Jul '20

07 Jul '20

Hi, I need to create some Windows Templates for my client, and I am not quite familiar with the Windows sysprep installations. I read the "Sealing a Windows Virtual Machine for Deployment as a Template" on the Virtual Machine Management Guide. What I don't understand is the process of sealing a Windows VM. When should I use the /usr/share/ovirt-engine/conf/sysprep/sysprep.* files? at the creation of the VM that will be a template at the end? or at the creation of new VMs based on the template? When should I use the /etc/ovirt-engine/osinfo.conf.d/xx.files.properties? at the creation of the VM that will be a template at the end? or at the creation of new VMs based on the template? What is the difference between : "Use Cloud-Init/Sysprep" in the VM edit window and the RUN Once window? For me it is not clear, could someone help me to understand. Regards.

Hi Erez, would you like to use the backup tool to backup your self Hosted Engine from iSCSI, then restore to the Gluster of NFS storage? In this way, you can migration as you want. If you are looking forward to a backup tool, maybe you can try Vinchin Backup & Recovery, which provides the solution. Hope you can solve your question soon. Thanks

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,
