The most up to date information is here: https://www.ovirt.org/develop/release-management/features/storage/increment… However the extents API is also outdated in the feature page. We are working on updating it. So here is example: First you must start backup with from_checkpoint_id argument: backup = backups_service.add( types.Backup( disks=disks, from_checkpoint_id="checkpoint-id", ) ) > "checkpoint-id" is the checkpoint created in the last backup. This starts a backup in in incremental mode. Dirty extents are available only in this mode. Then you start a transfer for download, using the backup id: transfer = imagetransfer.create_transfer( connection, disk, types.ImageTransferDirection.DOWNLOAD, backup=types.Backup(id=backup_uuid)) The transfer.transfer_url is the URL to download from, for example: https://host:54322/images/53787351-3f72-44a1-8a26-1323524fac4a Connect to host:54322 and send this request: GET /images/53787351-3f72-44a1-8a26-1323524fac4a/extents?context=dirty And parse the return json list, containing objects like: [ {"start": 0, "length": 65536, "dirty": true}, {"start": 65536, "length": 1048576, "dirty": false}, ... ] For example code of using the imageio API, see imageio http backend: https://github.com/oVirt/ovirt-imageio/blob/d5aa0e1fe659f1bf1247516f83c71e0… https://github.com/oVirt/ovirt-imageio/blob/d5aa0e1fe659f1bf1247516f83c71e0… We are adding a ImageioClient API that makes it easier to consume without writing any HTTP code: https://gerrit.ovirt.org/c/110068 With this you can use: with ImageioClient(transfer.transfer_url, cafile=args.cafile) as client: for extent in client.extent("dirty"): if extent.dirty: print("##dirty start={} length={}".format(extent.start, extent.length)) client.write_to(sys.stdout.buffer, extent.start, extent.length) print() This will stream the dirty extents to stdout. Not very useful as is, but illustrates how you can consume the data. Here is an example writing extents to a sparse stream format: https://gerrit.ovirt.org/c/110069 For complete backup example code see: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup_v… Note the new imagetransfer helper module: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/helpers/… Nir e-mail: l.kolacinski(a)storware.eu > <m.helbert(a)storware.eu> > > > > > *[image: STORWARE]* <http://www.storware.eu/> > > > > *ul.

Lots of problems with deploying the hosted-engine (ovirt 4.4 | CentOS 8.2.2004)
by jonas 13 Jul '20

13 Jul '20

Hi! I have banged my head against deploying the ovirt 4.4 self-hosted engine on Centos 8.2 for last couple of days. First I was astonished that resources.ovirt.org has no IPv6 connectivity, which made my initial plan for a mostly IPv6-only deployment impossible. CentOS was installed from scratch using the ks.cgf Kickstart file below, which also adds the ovirt 4.4 repo and installs cockpit-ovirt-dashboard & ovirt-engine-appliance. When deploying the hosted-engine from cockpit while logged in as a non-root (although privileged) user, the "(3) Prepare VM" step instantly fails with a nondescript error message and without generating any logs. By using the browser dev tools it was determined that this was because the ansible vars file could not be created as the non-root user did not have write permissions in '/var/lib/ovirt-hosted-engine-setup/cockpit/' . Shouldn't cockpit be capable of using sudo when appropriate, or at least give a more descriptive error message? After login into cockpit as root, or when using the command line ovirt-hosted-engine-setup tool, the deployment fails with "Failed to download metadata for repo 'AppStream'". This seems to be because a) the dnsmasq running on the host does not forward dns queries, even though the host itself can resolve dns queries just fine, and b) there also does not seem to be any functioning routing setup to reach anything outside the host. Regarding a) it is strange that dnsmasq is running with a config file '/var/lib/libvirt/dnsmasq/default.conf' containing the 'no-resolv' option. Could the operation of systemd-resolved be interfering with dnsmasq (see ss -tulpen output)? I tried to manually stop systemd-resolved, but got the same behaviour as before. I hope someone could give me a hint how I could get past this problem, as so far my ovirt experience has been a little bit sub-par. :D Also when running ovirt-hosted-engine-cleanup, the extracted engine VMs in /var/tmp/localvm* are not removed, leading to a "disk-memory-leak" with subsequent runs.

Revert to 4.3
by jb 13 Jul '20

13 Jul '20

Hello everybody, at to moment I run ovirt engine in a VM on a different server (no hosted engine) and I have two hosts. One is only a backup and is not running. I would like to install a new ovirt engine 4.4 VM and use the backup host. And if this is running fine in some month I would migrate the second host to 4.4. The Problem is only that I have to upgrade the data center compatibly mode to 4.4 and with that I'm a bit afraid. Is it possible, to downgrade the compatibility mode, when something unsuspected is happen? The original 4.3 engine VM I would like to have untouched, that I can go back if is necessary. Regards Jonathan

Not able to asign IB network to IB Bond

[v8.24.0-52.el7_8.2 try http://www.rsyslog.com/e/2222 ] I think that this is this bug : https://bugzilla.redhat.com/show_bug.cgi?id=1732918 However it's CLOSED INSUFFICIENT_DATA with last message being "Closing with insufficient data. Please reopen if you can provide needed info." Is my understanding correct that only RedHat employees can reopen closed bugs? I have encountered quite a lot of situations where I'm facing an issue covered by such a closed bug with a "please reopen if you can provide info" msg, but frustratingly not being able to do so...

Is there a way to access VM data that is stored using iscsi block storage outside of the ovirt platform ?
by Kevin Doyle 10 Jul '20

We have had problems trying to get our broken hosted engine to work. The datastore for all the VM's was stored in an iscsi storage that was deactivated before the platform went down, I am now looking for a way to access this data and start the VM's outside of a running hosted-engine Can I build an new ovirt standalone engine on a new bare metal remote server and connect to the hosts and start up the domain ? I would be interested in your thoughts. The problem with rebuilding the hosted-engine is that it cannot reuse the lun dedicated for the hosted-engine. I have tried to rebuild using NFS but it complains about not seeing the master domain thanks Kevin
