Error: Adding new Host to ovirt-engine

Hi,
Can't add new host to ovirt engine, because the following error:

Error Java SDK Issue??
by Geschwentner, Patrick
Dear Ladies and Gentlemen!
I am currently working with the java-sdk and I encountered a problem.
If I would like to retrieve the disk details, I get the following error:
Disk currDisk = ovirtConnection.followLink(diskAttachment.disk());
The Error is occurring in this line:
[cid:image001.png@01D44537.AF127FD0]
The getResponst looks quiet ok. (I inspected: [cid:image002.png@01D44537.AF127FD0] and it looks ok).
Error:
wrong number of arguments
The code is quiet similar to what you published on github (https://github.com/oVirt/ovirt-engine-sdk-java/blob/master/sdk/src/test/j... ).
Can you confirm the defect?
Best regards
Patrick

I agree. It would be nice if we can do:
$ mkdir -p backups/vm-id
$ download_disk_snapshots.py --backup-dir backups/vm-id ...
$ upload_disk_snapshots.py --backup-dir backups/vm-id ...
download_disk_snapshots.py will download vm ovf and all disks.
upload_disk_snaphsots.py
would take the output of download_disk_snapshots.py and create a new vm.
> I suppose that the best thing is to discard the gerrit, and to propose first what you want with 'download_disk_snapshot.py' and 'upload_disk_snapshot.py' and then act accordingly (several patch). Do you agree?
This is a bigger change that can take more time. I think we better fix
the issues in the current
scripts - the first one is the missing attach disk that you fix in your patch.
Since you posted this fix with a lot of other unrelated fixes (some
wrong or unneeded),
we cannot merge it. This is another reason to post minimal patches
that do one fix.

I make these changes to help a little since you would help me by solving the bug. I don't code in Python, I code in Java, using Java-sdk and the bug is a major limitation in my software, so I want resolve this bug (1 year old). =( I hope you understand. :)
Sure, I understand.
If you don't time to work on this, some other developer can take over
this patch.
The bug should be fixed by:
https://gerrit.ovirt.org/c/108991/
It would be nice if you can test this. I started a build here:
https://jenkins.ovirt.org/job/ovirt-engine_standard-check-patch/5867/
When the build is ready, you will be able to install engine from this
build by adidng
a yum repo with the baseurl:
https://jenkins.ovirt.org/job/ovirt-engine_standard-check-patch/5867/arti...
Note that this requires CentOS 8.1. If you want to test on CentOS 7,
you need to wait until
the fix will be backported to 4.3, or since you like Java, maybe port
it yourself?
Note also that we have a much more advanced backup and restore options:
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup...
Here is example run I did yesterday:
I started with full backup of a running vm:

[ 4.1 ] Incremental backup completed successfully
This backup is tiny since the only thing changed was new directory created
on the vm, and some system logs modified since the full backup.
Then I rebased the incremental backup on top of the full backup:
cd home/nsoffer/tmp/backups/test-nfs
qemu-img rebase -u -b
566e6aa6-575b-4f83-88c9-e5e5b54d9649.202005132336.full.qcow2 -F qcow2
566e6aa6-575b-4f83-88c9-e5e5b54d9649.202005132347.incremental.qcow2
This images are now a valid qcow2 chain that can be uploaded using
upload_disk.py:
$ python3 upload_disk.py --engine-url https://engine3/ --username
admin@internal --password /home/nsoffer/.config/ovirt/engine3/password

The result is a single qcow2 disk on the domain iscs2-1.
I created a new vm from this disk.
This backup script is not complete yet, we don't download the VM OVF
in each backup, and we don't
create the VM from the OVF. These features should be added later.
You may want to start testing and intergating this code instead of the
snapshot based download.

Cant get Sysprep to insert product key in Win2016 guest on RHV 4.3
by Lynn Dixon
I am trying to create a basic Windows server 2016 template in RHV 4.3 .
I've installed the OS from the Windows DVD, and installed all the RHV
tools, and drivers. Then I do a sysprep on my windows VM and make a
template from it.
I'd like to inject the product key when the template is cloned. I thought
if we define the product key
in /etc/ovirt-engine/osinfo.conf.d/10-productkeys.properties. with
something like this:
# Windows2016x64(29, OsType.Windows, true); os.windows_2016x64.id.value =
29 os.windows_2016x64.name.value = Windows 2016 x64
os.windows_2016x64.derivedFrom.value = windows_2012R2x64
os.windows_2016x64.cpu.unsupported.value = conroe, penryn, nehalem,
opteron_g1 os.windows_2016x64.sysprepPath.value =
${ENGINE_USR}/conf/sysprep/sysprep.2k16x64
os.windows_2016x64.productKey.value = MY-WIN-PRODUCT-KEY
That it would insert the product key when we tick the "Cloud Init /
Sysprep" box on the run-once dialog. Now, I know this is semi-working,
because all the other things I define in the run-once dialog after clicking
sysprep works: Admin password, hostname, etc. But NOT the product key!
I have even tried hard coding the product key in the sysprep.2k16x64 file
and no luck.
What am I doing wrong here?

Which conflict?
This looks like a reply, but there is no context from the original message.

Re: package conflicts when executing dnf update

Hi,
I have exactly the same problem. Fresh install of CentOS 8.1, did the install of oVirt-4.4-Release (added new host). And now I have this conflict…
Is there any solution to this?
