oVirt and CentOS Stream
by Sandro Bonazzola 26 Sep '19

26 Sep '19

Progress cannot be made without change. As technologists, we recognize this every day. Most of the time, these changes are iterative: progressive additions of features to projects like oVirt. Sometimes those changes are small, and sometimes not. And that’s, of course, just talking about our project. But one of the biggest strengths of our community’s software is that we are not alone, and because of that, changes to other projects have ripple effects that can affect our own, even in positive ways. This week, our collaborators in the CentOS Project have announced a change <https://lists.centos.org/pipermail/centos-announce/2019-September/023449.ht…> in the way their software is released moving forward. Beyond this week release of CentOS Linux 8, the CentOS team has announced CentOS Stream, a rolling release distribution that will be the "midstream" between Fedora and Red Hat Enterprise Linux. To be clear, Fedora will remain as the first upstream of RHEL. But when RHEL branches off, CentOS will be upstream for ongoing work on those RHEL versions. This change gives public visibility into ongoing work on released RHEL, and a place for developers and community projects like ours to collaborate at that level. CentOS has been heading in the direction of Stream for quite some time. CentOS SIGs — the special interest groups for virtualization, storage, config management, and so on — have given our project a way to provide input into the CentOS platform. Now, though, we can actually provide direct improvements or fixes to CentOS Stream platform that will be beneficial to our project. Long-term, those project-specific changes can find their way into the next release of RHEL, providing smoother transitions for those users of our downstream projects. We expect the positive effects to extend beyond our own project’s ecosystem. Through CentOS Stream, developers will have early access to new features and content that are being built into the upcoming RHEL version. This will help to allow next-generation applications to have compatibility with future versions of RHEL. The benefits of these changes are clear for ecosystem developers working on projects such as ours, writing hardware drivers, or extending protocols for RHEL. As we push the innovations that start in Fedora through the new CentOS Stream, the community will have a clear vision of the future of Red Hat Enterprise Linux. For users of oVirt, we expect CentOS Stream to be the preferred upstream platform on which oVirt should be run, especially with the capability for our users to now contribute changes to our software and the community-built platform on which oVirt runs. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.

Re: Change hostname of physical hosts under an oVirt and Gluster combination
by Strahil 26 Sep '19

26 Sep '19

Unassigned in 99% of the cases means engine cannot communicate with vdsm.service on the host. Check that vdsm.service & glusterd.service are running. Check gluster volume status for each volume. If they are OK - from UI just select activate.

Is it really down ? Have you tried to migrate it to another host. I found out yesterday that one of my VMs was constantly reporting errors (relayed to snapshot delete) and the errors stopped when the system got migrated to another host.

Change hostname of physical hosts under an oVirt and Gluster combination
by TomK 26 Sep '19

26 Sep '19

Hey All, Would like to change the hostname of hosts within a gluster volume that's been added to oVirt. I also need to readd the bricks to the gluster volume under the new hostname. What's the recommended approach to do so when all this is added to oVirt? -- Thx, TK.

Managed Block Storage: ceph detach_volume failing after migration
by Dan Poltawski 25 Sep '19

25 Sep '19

On ovirt 4.3.5 we are seeing various problems related to the rbd device staying mapped after a guest has been live migrated. This causes problems migrating the guest back, as well as rebooting the guest when it starts back up on the original host. The error returned is ‘nrbd: unmap failed: (16) Device or resource busy’. I’ve pasted the full vdsm log below. As far as I can tell this isn’t happening 100% of the time, and seems to be more prevalent on busy guests. (Not sure if I should create a bug for this, so thought I’d start here first) Thanks, Dan Sep 24 19:26:18 mario vdsm[5485]: ERROR FINISH detach_volume error=Managed Volume Helper failed.: ('Error

Urgent help needed / Snapshot deletion failure
by smirta＠gmx.net 25 Sep '19

25 Sep '19

Dear all we are desperate We have tried to delete a Snapshot and it hangs at merging the snapshots. We've found out that this is a known bug because the merge process is being called with wrong parameters according to the bug report https://bugzilla.redhat.com/show_bug.cgi?id=1601212. The Snapshot's Disks are in illegal state and the VM is locked. Since it is a very important VM for our non-profit organization, we need to have this machine back online as soon as possible. Is there a way to fix this without updating to qemu-kvm-ev-2.12.0? At least back to the state before the deletion would be fantastic.

How to delete obsolete Data Centers with no hosts, but with domains inside
by Claudio Soprano 25 Sep '19

25 Sep '19

Hi to all, We are using ovirt to manage 6 Data Centers, 3 of them are old Data Centers with no hosts inside, but with domains, storage and VMs not running. We left them because we wanted to have some backups in case of failure of the new Data Centers created. Time pass and now we would like to remove these Data Centers, but we got no way for now to remove them. If we try to remove the Storage Domains (using remove o destroy) we get "Error while executing action: Cannot destroy the master Storage Domain from the Data Center without another active Storage Domain to take its place. -Either activate another Storage Domain in the Data Center, or remove the Data Center. -If you have problems with the master Data Domain, consider following the recovery process described in the documentation, or contact your system administrator." if we try to remove the Data Center directly we get "Error while executing action: Cannot remove Data Center. There is no active Host in the Data Center." How can we solve the problem ? It can be done via ovirt-shell or using some script or via ovirt management interface ? Thanks in advance Claudio

Add External Provider - OpenStack Glance - Test Failed - "Failed to communicate with the External Provider"
by Pravin Mohandass 25 Sep '19

25 Sep '19

We have installed Ovirt Manager 4.3 with couple of KVM compute host added into cluster. When we add OpenStack Glance as an External Provider, failing with following error message - "Failed to communicate with the External Provider" We are able to add the external provider for Openstack Neutron and Openstack Cinder and import the storage and network in to ovirt manager and use it for vm. We are getting following error message on engine.log file "Failed with error PROVIDER_FAILURE and code 5050". But we are able to fetch the images using postman tool. Requesting you to provide some insights on adding the Glance provider.

Messed up 4.2.3.1 installation - SSL handshake ERROR
by souvaliotimaria＠mail.com 25 Sep '19

25 Sep '19

Hello, everyone! So, I have an experimental installation of ovirt 4.2.3.1 with 3 nodes and glustered. Recently I deployed a new installation with ovirt 4.3.5.2, 3nodes and glustered storage here as well. The thing is, in my enthousiasm I thought "hey! what if I can import the experimental nodes as hosts in the new installation in a new cluster and see what happens? Will the 4.3.5.2 engine see them? Probably yeah. But will it see the VMs I have there?" And so I imported the experimental nodes. Without detaching them from their hosted engine. I could see the only VM that was active at the moment and not one of the suspended ones and of course I could not see the 4.2.3.1 HE VM. I have removed the hosts from the new installation and I have tried reconnecting the old engine and its nodes. Passwordless ssh works just fine, but the problem persists. hosted-engine --vm-status reports stale-data on node 2 and node 3 The thing is I know I messed the experimental installation (and I blame only my curiosity), SSL handshake is no longer feasable and I can't remove the hosts from the initial Cluster to Import them again. Basically everything is either in the process of activating without ever being able to do so or down or Non responsive. I would like to find a way around this, as I have seen in other posts in the ovirt forum that the SSL handshake error appears in some other cases and I would like to have a know-how if an occasion like this occurs in the future in production. Is it possible to re-deploy the engine on the nodes and not lose the glustered space or the existing VMs? Can the HE be destroyed and then deployed from scratch? What about the glustered space and the VMs' space? Will the VMs just take up space without being able to neither bring them up nor destroy them? I know I'm asking a lot and it was my fault to begin with but I am really curious if we can see this through. Thanks in advance

oVirt node - post-upgrade tasks
by dan.munteanu＠mdc-berlin.de 25 Sep '19

25 Sep '19

Dear oVirt community, recently I've started to use oVirt as a replacement for KVM + VirtManager and I've decided to use the oVirt Node installed on Dell EMC servers with self-hosted engine. So far, everything works fine, except that, each time I'm updating the nodes, I must reinstall Dell OMSA needed by the monitoring system (via SNMP). Is there any way to automatize the OMSA installation as a post-upgrade task/hook? Thank you Dan

24 Sep '19

Dear oVirt, I have executed some tests regarding IO disk speed on the VMs, running on shared storage and local storage in oVirt.

Internal Memory filter not satisfied question

Dear oVirt, I need help clarifying how internal memory filter is used, at which values it looks at.

Unexpected SSO error with first task
by Vrgotic, Marko 24 Sep '19

24 Sep '19

Dear oVirt, In our software tests, we deploy oVirt VMs using ansible and teardown also using ansible. We noticed that each time we run nightly tests, using Jenkins user in ovirt, in one of the Jobs, first task, creating VM, fails with following error, TASK [Login to oVirt] ********************************************************** An exception occurred during task execution. To see the full traceback, use -vvv. The error was: AuthError: Error during SSO authentication invalid_grant : The provided authorization grant for the username and password has expired. fatal: [PVyrZMy0-csm-2.avinity.tv<http://pvyrzmy0-csm-2.avinity.tv/> -> localhost]: FAILED! => {"changed": false, "msg": "Error during SSO authentication invalid_grant : The provided authorization grant for the username and password has expired."} Immediately after, Token seem to be renewed and all other VMs are created without issue. The play looks like following: --- # file: provision-ovirt.yml - name: Create VM in OVirt hosts: ovirt-vms gather_facts: false vars: - state: running pre_tasks: - name: Login to oVirt delegate_to: localhost ovirt_auth: url: "{{ ovirt_engine_url }}" username: "{{ ovirt_engine_user }}" password: "{{ ovirt_engine_password }}" ca_file: "{{ ovirt_engine_cafile | default(omit) }}" insecure: "{{ ovirt_engine_insecure | default(true) }}" run_once: true tasks: - name: "Get agent keys" delegate_to: localhost command: ssh-add -L register: ssh_agent_pubkeys run_once: true changed_when: False - name: Create new VMs from template delegate_to: localhost ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ inventory_hostname_short }}" nics: - name: nic1 profile_name: tenant1 interface: virtio cloud_init_nics: - nic_name: eth0 nic_boot_protocol: dhcp nic_on_boot: true cloud_init: host_name: "{{ inventory_hostname_short }}" authorized_ssh_keys: "{{ ssh_agent_pubkeys.stdout }}" state: "{{ state }}" cluster: "{{ovirt_cluster}}" template: "{{ images_to_template[os_image] }}" instance_type: "{{ os_flavor_to_ovirt_instance_type[os_flavor] }}" - name: "Wait until the ansible user can log into the host (cloud-init needs to have finished)" command: ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no {{ansible_user}}@{{inventory_hostname}} exit register: ssh_output delegate_to: localhost until: ssh_output.rc == 0 retries: 30 delay: 5 changed_when: False post_tasks: - name: Logout from oVirt delegate_to: localhost run_once: true ovirt_auth: state: absent ovirt_auth: "{{ ovirt_auth }}" tags: - always How does token relates to user session in oVirt? We would expect that once we logout, token should be expired and upon new login just get renewed/new token to proceed. Is it a bug? Is it in the play that we are doing something incorrectly?

Reboot a guest via ansible in oVirt
by Gianluca Cecchi 24 Sep '19

24 Sep '19

Hello, I see that there is this Ansible module for vSphere that contains also the state "restarted": https://docs.ansible.com/ansible/latest/modules/vmware_guest_powerstate_mod… For oVirt I see the ovirt_vm module where state can be one of: [ absent, next_run, present, registered, running, stopped, suspended, exported ] Can we think to add a restart / restarted one to it too? BTW: I see discrepancy between this page: https://www.ovirt.org/develop/release-management/features/infra/ansible_mod… where many module names and links to github source are plural (eg ovirt_disks) and actual ansible docs and github sources that are singular (eg. ovirt_disk) Thanks, Gianluca

ovirtmgmt STP disabled - any reason behind that
by Strahil Nikolov 23 Sep '19

23 Sep '19

Hi All, I recently got an issue and due to lack of debug time , I'm still not sure if it was a loop on the network.Can someone clarify why the ovirtmgmt bridge has STP disabled ? Any reason behind that ? Also, what is the proper way to enable STP on those bridges ? For now , I have set highest priority of the STP on my router and I don't expect the issue to reoccur (if it really was a loop), but I want to avoid future issues like that.

23 Sep '19

Recently both oVirt node and Hypervisor have moved to gluster v6 (although I have moved a little bit earlier). For me v6 of Gluster is quite stable and if you dig up really nice , you will be able to even setup 'gtop' which gives great info. Ovirt is quite well integrated with gluster - doing health checks ,provide monitoring, allow creating additional gluster volumes and many more. Still, if you have FC available - it should be way easier to setup and tune. Docs are one of the weak stuff , but you can always check RHV (4.0+) and Oracle docs - as oVirt is upstream of RedHat's and Oracle's Virtualization.

Hey All, Seeing GlusterFS up to version 7, do any of the oVirt versions support anything higher then 3.X? Or is Gluster not the preferred distributed file system choice for oVirt? -- Thx, TK.

On the opposite - ovirt supports up to v6 of gluster and in cockpit, you can setup your hyperconverged setup (on gluster) abd your hosted engine ontop.

Linked Clones?
by marzoccafabio＠gmail.com 22 Sep '19

22 Sep '19

Hi, I am approaching and studying oVirt in order to propose the solution to a customer as a replacement for a commercial solution they have now. They only need Desktop virtualization. Sorry for the silly question, but I can't find a way to deploy a VM (template) to users as a "linked-clone", meaning that the users' image still refers to the original image but modification are written (and afterwards read) from a new location. This technique is called Copy-on-write. Can this be achieved with oVirt? Fabio

CentOS 7.7 has been released: note it's not supported for oVirt 4.2
by Sandro Bonazzola 19 Sep '19

19 Sep '19

CentOS 7.7 has been released this week. Please note that CentOS 7.7 is not supported for oVirt 4.2 and older releases. If you want to upgrade to CentOS 7.7 please upgrade to oVirt 4.3 too. If you don't plan to upgrade to oVirt 4.3 please be sure your yum repo files points to http://mirror.centos.org/centos/7.6.1810/ instead of http://mirror.centos.org/centos/7/. The http://mirror.centos.org/centos/7/ URL is now pointing to http://mirror.centos.org/centos/7.7.1908/ so yum upgrade will bring you 7.7 content which may break your 4.2 installation.

At least KVM can do that. If I understood correctly, you want a base disk for multiple VMs and the delta should be stored in separate disk, right? I am using VDO (with gluster) under my storage, so any duplicate data is deduplicated (and if yiu enable compression - compressed) by VDO. Have you thought about VDO - it works with almost any block storage ?Of course both technology will reduce the I/O performance compared to raw storage. Also, let's see if actually oVirt has such option...

how to add devices to a qemu config.xml of a virtual machine
by pascal＠butterflyit.com 19 Sep '19

Hi, I would like to be able to share a local folder with my remote desktop hosted by ovirt. Looking everywhere it seems that what is needed is to have spice-webdavd installed on the guest and have qemu set with this channel org.spice-space.webdav.0 I don't see in the web admin interface any ways to add those channels, but found on the web an addon which could maybe work vdsm-hook-qemucmdline but can't find a package compiled for the latest version and how to install it Also I noticed in the latest version of ovirt 4.3.5 there are 2 flags: Enable SPICE file transfer Enable SPICE clipboard copy and paste But that doesn't seem to change anything Any help appreciated

no hosted engine deploy while adding new host (oVirt 4.3.5)
by lars.stolpe＠bvg.de 18 Sep '19

18 Sep '19

I tryed to add a new host to my oVirt environment. I remember a checkbox whether the engine HA wil depoyed or not in oVirt 4.1. Now the environmentist oVirt 4.3.5. In the add host dialog windows I cant find that option anymore. In edit window after host installation ther ist also no hosted engine tab. hosted-engine --deploy don't ask, if it is an additional host (like it used to in 4.1), so it will install a new engine instead of depoying the existing engine. Is there a new way of depoying the engine HA to additional hosts?

I created a new ISO domain type via storage and pointed to an NFS share on the new storage, however it does not behave as I anticipated (I cannot see ISO's when creating new VM's) > > I suspect I missed a step - how are new ISO domains added to a cluster? > > Mark > > *** > Mark Steele > CIO / VP Technical Operations | TelVue Corporation > TelVue - We Share Your Vision > 16000 Horizon Way, Suite 100 | Mt.

ovirt-imagio-proxy upload speed slow

I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server. A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts. I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help. [root@blah-lab-engine ~]# engine-config -a |grep Upload UploadImageChunkSizeKB: 10240000 version: general [root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image ovirt-imageio-proxy-1.4.6-1.el7.noarch ovirt-imageio-common-1.4.6-1.el7.x86_64 ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch I have seen bugs reported to redhat about this but I am running above the affected releases. engine software is 4.2.8.2-1.el7 Any idea what we can tweak to open up this bottleneck?
