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

Fetch LUN ID for iSCSI Creation
by scott.fitzgerald＠oracle.com
Hi,
Using sysService.hostsService().hostService(host.id()).iscsiDiscover().iscsi(iscsiDetailsBuilder).send().discoveredTargets();
Where iscsiDetailsBuilder is IscsiDetailsBuilder iscsiDetailsBuilder = new IscsiDetailsBuilder().address(address).port(port);
I can fetch an iSCSI details container list, which contains the list of iSCSI targets. However, all values, except the address, port, portal and target string are null. I need the iSCSI LUN ID for automation of iSCSI creation. How can this be done via the SDK?
Thanks in advance.

[feedback needed] VirtIO Windows Drivers - new installer
by Steve Graham
Good morning -
I gave 0.1.173 from the 0.1.173-2 folder a try and the installation is
failing when trying to start the "virtio-win-guest-tools" service.
I tried multiple times and made sure I have administrative rights but can't
get it to work. I rebooted and tried again and that didn't help.
The system is 2012 R2 fully patched.
Thank you for all your hard work!

qemu-img process stuck
by Vojtech Juranek
Hi,
I'm doing some manual storage tests on RHEL 8.1 host (kernel version 4.18.0-107.el8.x86_64)
and run into following issue: when I try to move an image to block SD and RHEL 8.1 host is SPM,
qemu-img gets stuck. There are errors regarding blk_cloned_rq_check_limits on RHEL host
and also max_write_same_len on iscsi target (see bellow). iscsi target runs CentOS 7.6.
Before running qemu-img command, everything works fine (e.g. cat a file from iscsi target),
after running qemu-img, all IO on iscsi target is very slow.
When I try to run qemu-img command manually, it's very slow (1GB image take several minutes),
but finishes, when it's run from vdsm, it seems to be hung forever.
In similar cases I found it could be fixed by adjusting various values in
/sys/block/#DEVICE/queue/, but in this case, AFAICT all values are correct (same as on CentOS 7.7
host where everything work). Or it was identified as a bug in the kernel and was suggested to
upgrade to newer kernel.
Do you know any workaround, how to make it working? Or does it sound to you like a bug in kernel
which should be reported?
Thanks
Vojta
Example of qemu-img command:
[root@localhost ~]#/usr/bin/qemu-img convert -p -t none -T none -f raw /rhev/data-center/mnt/blockSD/ceba76d5-9d5d-4b04-9226-dffc7e77d4be/images/9aafce3d-53a6-41d7-b0d5-0e1db8aa59fc/7b7c7800-4837-4c3f-967c-c942b9c54e1b -O raw -W /rhev/data-center/mnt/blockSD/a17d7695-50fc-412e-abc7-008ebb6cdf23/images/9aafce3d-53a6-41d7-b0d5-0e1db8aa59fc/7b7c7800-4837-4c3f-967c-c942b9c54e1b

Creating bonds between Network Interface Cards with SDK
by Jamie Holohan
How can I bond one network interface to another using the SDK. I am try to perform the task in java but I'm unsure in what context I can find the utilities that will do this task.
The task can be performed in the OVM UI after a host has been initialised. By navigating from the side bar Compute -> Hosts -> (Select Host) -> (Host tabs) Network Interfaces ->
From here, click Setup Host Networks.
In the pop up you can select a network interface and drag it to another to create a bond between them.
How can I perform this step using the SDK. I am attempting to perform this in the context of a nicservice, found like this:
systemService.hostsService().hostService(hostObject).nicservice(NICObject)).get().send().nic();
but I can't find any methods associated with the retrieved NIC or nicservice that seem relevant to my task.

Planned restart of production services
by Evgheni Dereveanchin
Hi everyone,
I'll be restarting several production systems today to apply security
updates.
The following services may be unreachable for short periods of time:
- resources.ovirt.org - software repositories
- jenkins.ovirt.org - CI master
No new builds will be started during this period.
I will announce you once maintenance is complete.
