I can't download console.rdp on VM Portal with Firefox
by Dominique D 20 Aug '21

20 Aug '21

I am testing the lastest version of ovirt-engine 4.4.7.7-1 before updating. when I log into the VM portal and want to download the Remote Destop file (console.rdp) from a Windows VM, the file I receive is console.vv instead of console.rdp. So I have to rename the file to console.rdp. This problem is only with firefox. Edge and google chrome don't have this problem. Do you know why ?

Faster local disk for VM
by Shantur Rathore 20 Aug '21

20 Aug '21

Hi Users, Does oVirt support node local disk cache or scratch / transient disk for faster disk access? The idea is similar to options we get on cloud where one can attach fast node local scratch disk/ssd to the VM which gets deleted when VM dies. Thanks in advance. Kind Regards, Shantur

Ovirt-4.4.7 Adding host to existing cluster will attempt to run ovirt-hosted-engine-setup
by Paul-Erik Törrönen 15 Aug '21

15 Aug '21

I have an existing oVirt-installation to which I want to add a new host (from the UI). However the adding fails because oVirt tries to then install the ovirt-hosted-engine-setup despite the fact that in the New host-dialog I left the Choose hosted engine deployment action as None. As a result the installation then aborts: 2021-08-15 13:17:37 EEST - TASK [ovirt-host-deploy-vdsm : Install ovirt-hosted-engine-setup package] ****** 2021-08-15 13:17:37 EEST - 2021-08-15 13:17:37 EEST - fatal: [new.host]: FAILED! => {"changed": false, "failures": ["No package ovirt-hosted-engine-setup available."], "msg": "Failed to install some of the specified packages", "rc": 1, "results": []} 2021-08-15 13:17:37 EEST - { "status" : "OK", "msg" : "", "data" : { "uuid" : "98a244fb-15da-4192-a8fc-b23a5e5b7594", "counter" : 55, "stdout" : "fatal: [new.host]: FAILED! => {\"changed\": false, \"failures\": [\"No package ovirt-hosted-engine-setup available.\"], \"msg\": \"Failed to install some of the specified packages\", \"rc\": 1, \"results\": []}", "start_line" : 47, "end_line" : 48, "runner_ident" : "fe710372-fdb1-11eb-81f0-ecf4bb63099f", "event" : "runner_on_failed", "pid" : 24931, "created" : "2021-08-15T10:17:35.963320", "parent_uuid" : "ecf4bb63-099f-2448-1b83-0000000001a7", "event_data" : { "playbook" : "ovirt-host-deploy.yml", "playbook_uuid" : "8f70f945-4008-4159-b469-7ff04c9c242b", "play" : "all", "play_uuid" : "ecf4bb63-099f-2448-1b83-000000000006", "play_pattern" : "all", "task" : "Install ovirt-hosted-engine-setup package", "task_uuid" : "ecf4bb63-099f-2448-1b83-0000000001a7", "task_action" : "yum", "task_args" : "", "task_path" : "/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml:6", "role" : "ovirt-host-deploy-vdsm", "host" : "new.host", "remote_addr" : "new.host", "res" : { "msg" : "Failed to install some of the specified packages", "failures" : [ "No package ovirt-hosted-engine-setup available." ], "results" : [ ], "rc" : 1, "invocation" : { "module_args" : { "name" : [ "ovirt-hosted-engine-setup" ], "state" : "present", "allow_downgrade" : false, "autoremove" : false, "bugfix" : false, "disable_gpg_check" : false, "disable_plugin" : [ ], "disablerepo" : [ ], "download_only" : false, "enable_plugin" : [ ], "enablerepo" : [ ], ...

about the clonetype of the vm disk when vm is cloned from template
by Tommy Sway 14 Aug '21

14 Aug '21

There are some options for clone disk for other platform like oVirt. --clonetype [thin|full] A thin clone uses copy-on-write (COW) reflinked clone meaning it is dependent on the base template, but enables rapid cloning. Full clone will make a full physical copy hence not be dependent on the base template. Thin clone uses less space and will not be as performant as full clone, especially under heavy write workloads. By default a thin clone is created, great for testing; should be avoided in production environments. I want to know which type is oVirt using when we clone vm from template ?

Hosted engine on HCI cluster is not running
by David White 14 Aug '21

14 Aug '21

Hello, It appears that my Manager / hosted-engine isn't working, and I'm unable to get it to start. I have a 3-node HCI cluster, but right now, Gluster is only running on 1 host (so no replication). I was hoping to upgrade / replace the storage on my 2nd host today, but aborted that maintenance when I found that I couldn't even get into the Manager. The storage is mounted, but here's what I see: > [root@cha2-storage dwhite]# hosted-engine --vm-statusThe hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable. > > [root@cha2-storage dwhite]# systemctl status ovirt-ha-agent● ovirt-ha-agent.service - oVirt Hosted Engine High Availability Monitoring Agent > Loaded: loaded (/usr/lib/systemd/system/ovirt-ha-agent.service; enabled; vendor preset: disabled) > Active: active (running) since Fri 2021-08-13 11:10:51 EDT; 2h 44min ago > Main PID: 3591872 (ovirt-ha-agent) > Tasks: 1 (limit: 409676) > Memory: 21.5M > CGroup: /system.slice/ovirt-ha-agent.service > └─3591872 /usr/libexec/platform-python /usr/share/ovirt-hosted-engine-ha/ovirt-ha-agent > > Aug 13 11:10:51 cha2-storage.mgt.barredowlweb.com systemd[1]: Started oVirt Hosted Engine High Availability Monitoring Agent. Any time I try to do anything like connect the engine storage, disconnect the engine storage, or connect to the console, it just sits there, and doesn't do anything, and I eventually have to ctl-c out of it. Maybe I have to be patient?

Automigration of VMs from other hypervisors
by KK CHN 11 Aug '21

11 Aug '21

Hi list, I am in the process of migrating 150+ VMs running on Rhevm4.1 to KVM based OpenStack installation ( Ussuri with KVm and glance as image storage.) What I am doing now, manually shutdown each VM through RHVM GUI and export to export domain and scp those image files of each VM to our OpenStack controller node and uploading to glance and creating each VM manually. query 1. Is there a better way to automate this migration by any utility or scripts ? Any one done this kind of automatic migration before what was your approach? Or whats the better approach instead of doing manual migration ? Or only manually I have to repeat the process for all 150+ Virtual machines? ( guest VMs are CentOS7 and Redhat Linux 7 with LVM data partitions attached) Kindly share your thoughts.. Query 2. other than this 150+ VMs Redhat Linux 7 and Centos VMs on Rhevm 4.1, I have to migrate 50+ VMs which hosted on hyperV. What the method / approach for exporting from HyperV and importing to OpenStack Ussuri version with glance with KVM hpervisor ? ( This is the ffirst time I am going to use hyperV, no much idea about export from hyperv and Import to KVM) Will the images exported form HyperV(vhdx image disks with single disk and multiple disk(max 3 disk) VMs) can be directly imported to KVM ? does KVM support this or need to modify vhdx disk images to any other format ? What is the best approach should be in case of HyperV hosted VMs( Windows 2012 guest machines and Linux guest machines ) to be imported to KVM based OpenStack(Ussuri version with glance as image storage ). Thanks in advance Kris

Ubuntu 20.04 cloud-init
by Pavel Šipoš 11 Aug '21

11 Aug '21

Hi. We are using oVirt version 4.3.10.4-1.el7 I am trying to use clod-init function in ovirt to set password and add ssh keys for VM on first boot. It is working perfectly on Centos7, Centos8, but not with Ubuntu 20.04.02 . On VM Cloud-init package and quemu-guest-agent are installed, services are running - I checked that and then used Run once to test further but no luck. It looks like its not even trying to set anything. I am open to suggestions how to debug this. I see no errors if I look into /var/log/cloud-init logs on VM. Did anyone else had similar problem? Can anyone confirm that cloud-init function in ovirt should work with ubuntu 20.04? Packages used: cloud-init 21.2-3-g899bfaa9-0ubuntu2~20.04.1 qemu-guest-agent 1:4.2-3ubuntu6.17 I made ovirt template myself using packer (qemu) that also uses cloud-init for bootstrapping. Thank you in advance! Pavel -- -- Pavel Sipos, Arnes <pavel.sipos(a)arnes.si> ARNES, p.p. 7, SI-1001 Ljubljana, Slovenia T: +386 1 479 88 00 W: www.arnes.si, aai.arnes.si
