Error: Adding new Host to ovirt-engine

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

Merge rights changes in the oVirt Engine project
by Tal Nisan
Hi everyone,
As you probably know we are now in a mode in which we develop our next
zstream version on the master branch as opposed to how we worked before
where the master version was dedicated for the next major version. This
makes the rapid changes in master to be delivered to customers in a much
higher cadence thus affecting stability.
Due to that we think it's best that from now on merges in the master branch
will be done only by stable branch maintainers after inspecting those
closely.
What you need to do in order to get your patch merged:
- Have it pass Jenkins
- Have it get code review +2
- Have it mark verified +1
- It's always encourage to have it tested by OST, for bigger changes it's a
must
Once you have all those covered, please add me as a reviewer and I'll
examine it and merge if everything seems right, if I haven't done it in a
timely manner feel free to ping me.

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

CentOS Stream support
by Michal Skrivanek
Hi all,
we would like to ask about interest in community about oVirt moving to CentOS Stream.
There were some requests before but it’s hard to see how many people would really like to see that.
With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS.
So..would you like us to support CentOS Stream?
We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS?
There are some concerns about Stream being a bit less stable, do you share those concerns?
Thank you for your comments,

Almost two years ago I write on this issue https://bugzilla.redhat.com/show_bug.cgi?id=1539837#c6 about "before deprecate, let's help to migrate". For now I see that oVirt totally will disable QEMU RBD support and want to use kernel RBD module + python os-brick + userland mappers + shell wrappers.

I looked at the bugs and I see you've already identified the problem
and have patches attached, if you can submit the patches and verify
them perhaps we can merge the fixes

Issue: Device path changed after adding disks to guest VM
by Joy Li
Hi All,
I'm facing the problem that after adding disks to guest VM, the device
target path changed (My ovirt version is 4.3). For example:
Before adding a disk:
virsh # domblklist <vmname>
Target Source
---------------------------------------------------------
hdc -
vda /dev/mapper/3600a09803830386546244a546d494f53
vdb /dev/mapper/3600a09803830386546244a546d494f54
* vdc /dev/mapper/3600a09803830386546244a546d494f55*
vdd /dev/mapper/3600a09803830386546244a546d494f56
vde /dev/mapper/3600a09803830386546244a546d494f57
vdf /dev/mapper/3600a09803830386546244a546d494f58
After adding a disk, and then shutdown and start the VM:
virsh # domblklist <vmname>
Target Source
---------------------------------------------------------
hdc -
vda /dev/mapper/3600a09803830386546244a546d494f53
vdb /dev/mapper/3600a09803830386546244a546d494f54
*vdc /dev/mapper/3600a09803830386546244a546d494f6c*
* vdd /dev/mapper/3600a09803830386546244a546d494f55*
vde /dev/mapper/3600a09803830386546244a546d494f56
vdf /dev/mapper/3600a09803830386546244a546d494f57
vdg /dev/mapper/3600a09803830386546244a546d494f58
The devices' multipath doesn't map to the same target path as before, so in
my VM the /dev/vdc doesn't point to the old
/dev/mapper/3600a09803830386546244a546d494f55 anymore.
Anybody knows how can I make the device path mapping fixed without being
changed after adding or removing disks.
Many thanks in advance.

Vdsm: Small version numbering change?
by Milan Zamazal
Hi,
we have a nice coincidence now that Vdsm 4.40.40 corresponds to
ovirt-4.4.4 branch. Would we like to use this opportunity to make Vdsm
versions aligned with oVirt 4.4.* versions?
We can tag the next master build, which will be no longer part of
ovirt-4.4.4 branch, as v4.40.50. Or we could tag it as v4.40.500 to be
on the safe side, but both 4.4.3 and 4.4.4 had less than 10 tags on
master, so it's probably not needed and there is always v4.40.591-like
workaround available.
What do you think?
Regards,
Milan
