[VDSM] Started getting virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired
by Edward Haas 11 Jan '24

11 Jan '24

Hi, I have a VM which acts as an oVirt host with VDSM installed. I use it for testing without connecting it to Engine. Recently VDSM fails to come up and I see this error: Sep 26 17:58:18 localhost libvirtd: 2018-09-26 14:58:18.978+0000: 12176: error : virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired Any hint on how to generate or fetch a new certificate without the help of Engine? Thanks, Edy.

03 May '20

oVirt 4.4.0 Beta release refresh is now available for testing The oVirt Project is excited to announce the availability of the beta release of oVirt 4.4.0 refresh (beta 4) for testing, as of April 17th, 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 on top of oVirt 4.3. Important notes before you try it Please note this is a Beta release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production. In particular, please note that upgrades from 4.3 and future upgrades from this beta to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Beta require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Known Issues - ovirt-imageio development is still in progress. In this beta you can’t upload images to data domains using the engine web application. You can still copy iso images into the deprecated ISO domain for installing VMs or upload and download to/from data domains is fully functional via the REST API and SDK. For uploading and downloading via the SDK, please see: - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_d… - https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… Both scripts are standalone command line tool, try --help for more info. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Beta? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support only for file based storage. iSCSI/FC storage do not support 4k disks yet. - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

PoC - using pre-built VM images in OST
by Marcin Sobczyk 29 Apr '20

29 Apr '20

Hi, recently I've been working on a PoC for OST that replaces the usage of lago templates with pre-built, layered VM images packed in RPMs [2][7]. What's the motivation? There are two big pains around OST - first one is that it's slow and the second one is it uses lago, which is unmaintained. How is OST working currently? Lago launches VMs based on templates. It actually has its own mechanism for VM templating - you can find the ones that we currently use here [1]. How these templates are created? There is a multiple-page doc somewhere that describes the process, but few are familiar with it. These templates are nothing special really - just a xzipped qcow with some metadata attached. The proposition here is to replace those templates with RPMs with qcows inside. The RPMs themselves would be built by a CI pipeline. An example of a pipeline like this can be found here [2]. Why RPMs? It ticks all the boxes really. RPMs provide: - tried and well known mechanisms for packaging, versioning, and distribution instead of lago's custom ones - dependencies which permit to layer the VM images in a controllable way - we already install RPMs when running OST, so using the new ones is a matter of adding some dependencies How the image building pipeline works? [3] - we download a dvd iso for installation of the distro - we use 'virt-install' with the dvd iso + kickstart file to build a 'base' layer qcow image - we create another qcow image that has the 'base' image as the backing one. In this image we use 'virt-customize' to run 'dnf upgrade'. This is our 'upgrade' layer. - we create two more qcow images that have the 'upgrade' image as the backing one. On one of them we install the 'ovirt-host' package and on the other the 'ovirt-engine'. These are our 'host-installed' and 'engine-installed' layers. - we create 4 RPMs for these qcows: * ost-images-base * ost-images-upgrade * ost-images-host-installed * ost-images-engine-installed - we publish the RPMs to templates.ovirt.org/yum/ DNF repository (not implemented yet) Each of those RPMs holds their respective qcow image. They also have proper dependencies set up - since 'upgrade' layer requires 'base' layer to be functional, it has an RPM requirement to that package. Same thing happens for '*-installed' packages which depend on 'upgrade' package. Since this is only a PoC there's still a lot of room for improvement around the pipeline. The 'base' RPM would be actually built very rarely, since it's a bare distro, and the 'upgrade' and '*-installed' RPMs would be built nightly. This would allow us to simply type 'dnf upgrade' on any machine and have a fresh set of VMs ready to be used with OST. Advantages: - we have CI for building OST images instead of current, obscure template creating process - we get rid of lots of unnecessary preparations that are done during each OST run by moving stuff from 'deploy scripts' [4] to image-building pipeline - this should speed up the runs a lot - if the nightly pipeline for building images is not successful, the RPMs won't be published - OST will use the older ones. This makes a nice "early error detection" mechanism and can partially mitigate situations where everything is blocked because of some, i.e. dependency issues. - it's another step for removing responsibilities from lago - the pre-built VM images can be used for much more than OST - functional testing of vdsm/engine on a VM? We have an image for that - we can build images for multiple distros, both u/s and d/s, easily Caveats: - we have to download the RPMs before running OST and that takes time, since they're big. This can be handled by having them cached on the CI slaves though. - current limitations of CI and lago force us to make a copy of the images after installation so they can be seen both by the processes in the chroot and libvirt, which is running outside of chroot. Right now they're placed in '/dev/shm' (which would actually make some sense if they could be shared among all OST runs on the slave, but that's another story). There are some possible workarounds around that problem too (like running pipelines on bare metal machines with libvirt running inside chroot) - multiple qcow layers can slow down the runs because there's a lot of jumping around. This can be handled by i.e. introducing a meta package that squashes all the layers into one. - we need a way to run OST with custom-built artifacts. There are multiple ways we can approach it: * use 'upgrade' layer and not '*-installed' one * first build your artifacts, then build VM image RPMs that have your artifacts installed and pass those RPMs to OST run * add 'ci build vms' that will do both ^^^ steps for you Even here we can still benefit from using pre-built images - we can create a 'deps-installed' layer that sits between 'upgrade' and '*-installed' and contains all vdsm's/engine's dependencies. Some numbers So let's take a look at two OST runs - first one that uses the old way of working [5] and one that uses the new pre-built VM images [6]. The hacky change that allows us to use the pre-built images is here [7]. Here are some running times: - chroot init: 00:34 for the old way vs 14:03 for pre-built images This happens because the slave didn't have the new RPMs and chroot cached, so it took a lot of time to download them - the RPMs are ~2GB currently. When they will be available in cache it will get much closer to the old-way timing. - deployment times: * engine 08:09 for the old way vs 03:31 for pre-built images * host-1 05:05 for the old way vs 02:00 for pre-built images Here we can clearly see the benefits. This is without any special fine tuning really - even when using pre-built images there's still some deployment done, which can be moved to image-creating pipeline. Further improvements We could probably get rid of all the funny custom repository stuff that we're doing right now because we can put everything that's necessary to pre-built VM images. We can ship the images with ssh key injected - currently lago injects an ssh key for root user in each run, which requires selinux relabeling, which takes a lot of time. We can try creating 'ovirt-deployed' images, where the whole ovirt solution would be already deployed for some tests. WDYT?

ovirt-imageio image upload feedback on engine 4.4.0-31
by Guilherme De Oliveira Santos 28 Apr '20

28 Apr '20

Hi people, I recently had to upload an image on a 4.4.0-31 engine and Nir told me to share here the feedback. I installed ovirt-imageio-common-2.0.5-0.el8ev.x86_64 and created the following script to upload it using sdk: #!/usr/bin/bash python3 /root/ovirt-engine-sdk/sdk/examples/upload_disk.py \ --engine-url "https://`hostname`/" \ --username admin@internal \ --password-file pssword \ --cafile /tmp/ca.pem \ --disk-format qcow2 \ --disk-sparse \ --sd-name nfs_0 \ /tmp/rhel-guest-image-7.6-210.x86_64.qcow2 The image got uploaded pretty quickly and I didn't have any trouble... Cheers, Gui

Uploading iso / ovirt-imageio
by Artur Socha 27 Apr '20

27 Apr '20

Hi, After a long break I am trying setup my engine so that I could upload images (ISO) there and use them when spinning new VMs. First I tried recent master (FC31) and then latest 4.4 beta from RPMs (Centos8). I have ovirt-imageio daemon running on the same host engine is running. (with the simplest possible configuration - TLS disabled) Unfortunately when I hit 'test connection' in admin ui/storage/domain I keep seeing error message complaining about ovirt-imageio-proxy setup. I know that recently there has been quite a lot of changes related to the next version of imageio. Is there something else besides ovirt-imageio daemon that I should have installed/configured? Perhaps there is some documentation I could use? thanks! -- Artur Socha Senior Software Engineer, RHV Red Hat

Backup is not supported by the host, Ovirt 4.4 Beta
by francesco＠shellrent.com 26 Apr '20

26 Apr '20

Hi all, I'm trying to experiment with incremental backup using the example script provided on sdk git page (https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_v…) I installed a fresh engine on a CentOS 8 VM and installed a fresh node on CentOS 8 as well, connected to the engine without any problems. All libvirt packages version 5.6 and ovirt-imageio-common version 2.0.3 . Passing all the needed args to the script (I hardcoded connections var like user and password) it throws the following error: ``` [root@centos8 ~]# python3 backup_vm.py full --engine-url https://ovirt-engine-fqdn.com --username admin@internal --password-file ./passwd --backup-dir /home 11d70eb0-4d7c-4308-82a6-470e21d80ecd [ 0.0 ] Starting full backup for vm 11d70eb0-4d7c-4308-82a6-470e21d80ecd Traceback (most recent call last): File "backup_vm.py", line 397, in <module> main() File "backup_vm.py", line 141, in main args.command(args) File "backup_vm.py", line 154, in cmd_full backup = start_backup(connection, args) File "backup_vm.py", line 247, in start_backup disks=disks File "/usr/lib64/python3.6/site-packages/ovirtsdk4/services.py", line 33583, in add return self._internal_add(backup, headers, query, wait) File "/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py", line 232, in _internal_add return future.wait() if wait else future File "/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py", line 55, in wait return self._code(response) File "/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py", line 229, in callback self._check_fault(response) File "/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py", line 132, in _check_fault self._raise_error(response, body) File "/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py", line 118, in _raise_error raise error ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Cannot backup VM. Backup is not supported by the host (centos8).]". HTTP response code is 409. ``` The VM is created from centOS 7 template imported from ovirt-image-repository, and the options "Enable Incremental Backup" on the disk is ticked. I'm definitely missing something... But what? On the top of the script, I read "Using this example requires a special libvirt version supporting incremental backup.". Which version of libvirt? I guessed the 5.6 (or at least not the 4.5 shipped in CentOS 7). Thank you for your time and help, Francesco

Changing vdsm version installed on host
by Vojtech Juranek 21 Apr '20

21 Apr '20

Hi, can anybody give me a hint which component is responsible for installing host when I add a host in engine UI? Or how to change vdsm version installed this way on the host? It installs vdsm-4.40.2: [root@localhost ~]# rpm -q ovirt-release44-pre ovirt-release44-pre-4.4.0-0.11.beta4.el8.noarch [root@localhost ~]# rpm -q vdsm vdsm-4.40.2-1.el8.x86_64 We need newer version of vdsm (at least 4.40.11) to work properly with imageio 2.0. vdsm 4.40.13 can be pushed by running dnf update, but it's not very user friendly (moreover imageio service needs to be restarted after update and it's not obvious for the user t do so), so I'd like to change it to install 4.40.13 automatically when installing all other ovirt stuff. Thanks Vojta
