ovirt-system-tests hosted-engine suites and CentOS Stream - current status
by Yedidyah Bar David 18 Mar '21

18 Mar '21

Hi all, Right now, ovirt appliance is built nightly, and publishes (to ovirt-master-snapshot) two packages: ovirt-engine-appliance (the "regular" one, based on CentOS Linux) and ovirt-engine-appliance-centos-stream (based on CentOS Stream). This can already be used by anyone that wants to try this manually. For trying in CI: 1. A pending patch to ost-images [1] can be merged once it passes the manual build I ran (link in a gerrit comment there). Should take a few more hours. This patch changes the existing image that was generated, called ost-images-el8stream-he-installed, to include a stream appliance (from current repos). 2. A patch for OST [2] can be used, as needed, for manual runs. I updated it now to expect the output of [1] once it's merged, so should probably be rebased and/or 'ci test/ci build' once [1] is merged (and image is published). TODO: 1. Decide how we want to continue, going forward. If we aim at complete move to Stream in 4.4.6, perhaps now is the time to start... An alternative is to somehow support both in parallel - will be more complex, obviously. 2. Handle ovirt-node Best regards, [1] https://gerrit.ovirt.org/c/ost-images/+/113633 [2] https://gerrit.ovirt.org/c/ovirt-system-tests/+/112977 -- Didi

Migrate VMs between DCs
by Daniel Gurgel 18 Mar '21

18 Mar '21

How to migrate virtual servers between different data centers that do not share the same SAN? There are limitations, including connection technology, depending on the Storage Model used. For example, Dell PowerStore uses only 1 iSCSI network and Dell EMC Compellent, 2 separate iSCSI networks. This connection is not possible, even for security and redundancy reasons. Exports Domains are marked as discontinued in 4.4.x. Are there plans for 4.4.x or 4.5.x Live Migrate Storage to be implemented?

docs: pointers to more in-depth internals?
by Greg King 16 Mar '21

16 Mar '21

I am new to vdsm and trying to understand the architecture/internals much better The ovirt documentation for architecture I have found so far seems to be relatively high level My effort to understand the architecture by walking through the vdsm code using pdb/rpdb is slow and probably not all that efficient Does anyone have pointers to documentation that might explain the vdsm modules, classes and internals a little more in depth? I'd also like to understand where I might be able to add rpdb.set_trace() so I can step through functions being called in libvirt.py [oracle-email-sig-198324-355094] Gregory King | Software Development Manager | +1.303.272.2427 Oracle Virtualization Sustaining Engineering 500 Eldorado Boulevard Build 5 | Broomfield Colorado 80021 Mobile: +1.303.968.8169 | Fax: +1.303.272.2427

Engine upgrade fails with virtio_scsi_multi_queues_enabled does not exist
by Vojtech Juranek 16 Mar '21

16 Mar '21

Hi, when I try to upgrade my engine with built artifacts (e.g. [1]), it fails with: psql:/usr/share/ovirt-engine/dbscripts/create_views.sql:1000: ERROR: column vm_templates.virtio_scsi_multi_queues_enabled does not exist LINE 86: vm_templates.virtio_scsi_multi_queues_enabled AS virtio_... ^ FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/create_views.sql Same issue happens when I tried to update my dev engine with local build. However, OST is passing [2]. Any idea what's wrong? I don't see anything wrong in [3], which is probably the culprit, but I haven't much experience with engine/db though. Or maybe some issue on my side?

Where to place useful Ansible recipe?
by Vojtech Juranek 11 Mar '21

11 Mar '21

Hi, the result of working on BZ #1310330 [1] is Ansible recipe, which removes multipath devices for unzoned LUN from the hosts. The recipe is attached to the BZ, but it would be good to put it somewhere in into the code base. IIUC Ansible recipes contained in engine project are used internally by the engine, but this is not the right place (can be in the future if we implement some UI in the engine which will trigger this recipe). Is ovirt-engine/contrib [2] the right place or is there a better place? Thanks Vojta [1] http://bugzilla.redhat.com/1310330 [2] https://github.com/oVirt/ovirt-engine/tree/master/contrib
