Network Address Change
by Paul.LKW 28 Dec '22

28 Dec '22

Hi All: I just has a case, I need to change the oVirt host and engine IP address due to data center decommission I checked in the hosted-engine host there are some files I could change ; in ovirt-hosted-engine/hosted-engine.conf ca_subject="O=simple.com, CN=1.2.3.4" gateway=1.2.3.254 and of course I need to change the ovirtmgmt interface IP too, I think just change the above line could do the tick, but where could I change the other host IP in the cluster ? I think I have to be lost all the host as once changed the hosted-engine host IP as it is in diff. sub net. Does there any command line tools could do that or someone has such experience could share? Best Regards, Paul.LKW

looking for some ISV backup software which integrates the backup API
by Nathanaël Blanchet 08 Jun '22

08 Jun '22

Hello, We are about to change our backup provider, and I find it is a great chance to choose a full supported ovirt backup solution. I currently use this python script vm-backup-scheduler (https://github.com/wefixit-AT/oVirtBackup) but it is not the workflow officially suggested by the community (https://www.ovirt.org/develop/release-management/features/storage/backup-re…) I've been looking for a long time an ISV who supports such an API, but the only one I found is this one : Acronis Backup Advanced suggested here https://access.redhat.com/ecosystem/search/#/ecosystem/Red%20Hat%20Enterpri… I ran the trial version, but it doesn't seem to do better than the vm-backup-scheduler script, and it doesn't seem to use the backup API (attach a clone as a disk to an existing vm). Can you suggest me some other ISV solutions, if they ever exist... or share me your backup experience?

VM HostedEngine is down with error
by souvaliotimaria＠mail.com 26 May '22

26 May '22

Hello everyone, I have a replica 2 + arbiter installation and this morning the Hosted Engine gave the following error on the UI and resumed on a different node (node3) than the one it was originally running(node1). (The original node has more memory than the one it ended up, but it had a better memory usage percentage at the time). Also, the only way I discovered the migration had happened and there was an Error in Events, was because I logged in the web interface of ovirt for a routine inspection. Βesides that, everything was working properly and still is. The error that popped is the following: VM HostedEngine is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2020-09-01T06:49:20.749126Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2020-09-01T06:49:20.927274Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x7,drive=drive-ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,id=ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,bootindex=1,write-cache=on: Failed to get "write" lock Is another process using the image?. Which from what I could gather concerns the following snippet from the HostedEngine.xml and it's the virtio disk of the Hosted Engine: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads' iothread='1'/> <source file='/var/run/vdsm/storage/80f6e393-9718-4738-a14a-64cf43c3d8c2/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7'> <seclabel model='dac' relabel='no'/> </source> <target dev='vda' bus='virtio'/> <serial>d5de54b6-9f8e-4fba-819b-ebf6780757d2</serial> <alias name='ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> I've tried looking into the logs and the sar command but I couldn't find anything to relate with the above errors and determining the reason for it to happen. Is this a Gluster or a QEMU problem? The Hosted Engine was manually migrated five days before on node1. Is there a standard practice I could follow to determine what happened and secure my system? Thank you very much for your time, Maria Souvalioti

OVS switch type for hosted-engine
by Devin A. Bougie 06 May '22

06 May '22

Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated. Many thanks, Devin

USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

Install hosted-engine - Task Get local VM IP failed
by florentl 10 Mar '22

10 Mar '22

Hi all, I try to install hosted-engine on node : ovirt-node-ng-4.2.3-0.20180518. Every times I get stuck on : [ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed": true, "cmd": "virsh -r net-dhcp-leases default | grep -i 00:16:3e:6c:5a:91 | awk '{ print $5 }' | cut -f1 -d'/'", "delta": "0:00:00.108872", "end": "2018-06-01 11:17:34.421769", "rc": 0, "start": "2018-06-01 11:17:34.312897", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []} I tried with static IP Address and with DHCP but both failed. To be more specific, I installed three nodes, deployed glusterfs with the wizard. I'm in a nested virtualization environment for this lab (Vmware Esxi Hypervisor). My node IP is : 192.168.176.40 / and I want the hosted-engine vm has 192.168.176.43. Thanks, Florent

Host needs to be reinstalled after configuring power management
by Andrew DeMaria 02 Feb '22

02 Feb '22

Hi, I am running ovirt 4.3 and have found the following action item immediately after configuring power management for a host: Host needs to be reinstalled as important configuration changes were applied on it. The thing is - I've just freshly installed this host and it seems strange that I need to reinstall it. Is there a better way to install a host and configure power management without having to reinstall it after? Thanks, Andrew

Import an exported VM using Ansible
by paolo＠airaldi.it 25 Jan '22

25 Jan '22

Hello everybody! I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook. I'm able to: - Create a snapshot of the source VM - create a clone from the snapshot - remove the snapshot - attach an Export Domain - export the clone to the Export Domain - remove the clone - detach the Export domain from the source Datacenter and attach to the destination. Unfortunately I cannot find a module to: - import the VM from the Export Domain - delete the VM image from the Export Domain. Any hint on how to do that? Thanks in advance. Cheers. Paolo PS: if someone is interested I can share the playbook.

did 4.3.9 reset bug https://bugzilla.redhat.com/show_bug.cgi?id=1590266
by kelley bryan 10 Jan '22

I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log {2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information. Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431 or is it because the vm fails or dies or ???
