Vdsm stuck in get_dpdk_devices
by Nir Soffer
I'm seeing now new issue with latest vdsm 4.2.5:
On engine side, host is not responding.
On the host, vdsm is stuck waiting for stuck lshw child processes

I'm not sure it is reproducible, happened after I
- stop vdsmd supervdsmd sanlock wdmd
- install new sanlock version with unrelated fix
- start vdsmd
Running same command from the shell is successful:

-disable scsi -disable dmi -disable memory -disable cpuinfo > /dev/null
real 0m0.744s
user 0m0.701s
sys 0m0.040s
And create fairly large json, but this should not be an issue:
# lshw -json -disable usb -disable pcmcia -disable isapnp -disable ide
-disable scsi -disable dmi -disable memory -disable cpuinfo | wc -c

Do we have a flag to disable dpkd until this issue is fixed?

[ACTION REQUIRED] Dropping oVirt 4.1 in CI
by Ehud Yonasi
Hey everyone,
Since oVirt 4.1 has gone EOL, it is time to drop all related jobs in CI
which includes:
- All 4.1 jobs related
- All 4.1 change queue jobs
- The 'tested' repository under resources
- The 4.1 nightly snapshot repository jobs
Maintainers, if your projects have any dependencies on the resources
above, please be sure to update them to more up to date or stable
resources. In particular, to depend on any 4.1 packages, please use the 4.1
released repo at:
Thanks in advance for your cooperation,
Ehud.

[ATT] OST 'master' is now broken because of a change in CentOS - DEVELOPMENT BLOCKED
by Barak Korren
The openstack-java-glance-* packages in CentOS have been updated in a way
that is now incompatible with how engine had been using Glance.
This in turn causes any OST run to break ATM, which means no patches are
currently making it past OST and CQ and into the 'tested' and nightly
snapshot repositories.
So far we've only seen this affect 'master' but since the change was made
in CentOS, there is no reason to believe it will not break other version as
well.
A fix to engine to make it compatible with the new package had been posted
here:
https://gerrit.ovirt.org/c/93352/
Additionally, an issue in OST had made this harder to diagnose then it
should have been, and was fixed here:
https://gerrit.ovirt.org/c/93350/
Actions required:
1. Please avoid merging any unrelated patches until the issue is fixed
2. If you've merged any patches since Friday morning, please not that
there were probably removed from the change queue asfailed changes, ad
willl need to be resubmitted by either merging a newer patch to the
relevant project, commenting "ci re-merge please" on the latest merged
patch in Gerrit or resenting the Webhook event from GitHub.
3. If you can please help with reviewing, merging and back-porting the
patches above to speed up resolution of this issue.
Here is a list of project for which we've seen patches get dropped over the
weekend
- ovirt-provider-ovn
- ovirt-engine
- ovirt-ansible-vm-infra
- vdsm

[ OST Failure Report ] [ oVirt Master (ALL) ] [ 27-07-2018 ] [ 002_bootstrap.list_glance_images ]
by Dafna Ron
Hi,
We seem to have a problem in the OST tests that is causing failure in
multiple projects
The issue is that setting __name__ on local function is not working
correctly and we are exiting instead of skipping when Glance image is not
available.
We had the same issue on a different test where Milan fixed it:
https://gerrit.ovirt.org/#/c/93167/
but now it seems that we have the same issue on list_glace_images as well.

storage domain deactivating
by Hetz Ben Hamo
Hi,
As part of my "torture testing" to oVirt (4.2.4) I'm doing some testing
with 1 node where I shut down the HE and the machine (powering off, not
yanking the power cable) and rebooting to see it's survival status.
One of the weird thing that happens is that when the machine boots and it
starts the HE, it mounts the storage domains and everything works. However,
after few moments, 3 of my 4 storage domains (ISO, export, and another
storage domain, but not the hosted_engine storage domain) is being
automatically deactivted, with the following errors:
VDSM command GetFileStatsVDS failed: Storage domain does not exist:
(u'f241db01-2282-4204-8fe0-e27e36b3a909',)
Refresh image list failed for domain(s): ISO (ISO file type). Please check
domain activity.
Storage Domain ISO (Data Center HetzLabs) was deactivated by system because
it's not visible by any of the hosts.
Storage Domain data-NAS3 (Data Center HetzLabs) was deactivated by system
because it's not visible by any of the hosts.
Storage Domain export (Data Center HetzLabs) was deactivated by system
because it's not visible by any of the hosts.
However, when I see those message and I'm manually re-activating those
storage domains, all of them getting the status "UP" and there are no
errors and I can see disks, images, etc...
Should I open a bug in Bugzilla about this issue?
Thanks

OST: Cluster compatibility testing
by Milan Zamazal
Hi, CI runs now OST basic-suite-master periodically with data center and
cluster versions different from the default one on master. That tests
changes in master for breakages when run in older version compatibility
modes. Contingent failures are reported to infra.
If you make an OST test known not to run on older cluster versions
(e.g. < 4.1), you should mark the test with a decorator such as
@versioning.require_version(4, 1)
You can also distinguish cluster version dependent code inside tests by
calling
versioning.cluster_version_ok(4, 1)
See examples in basic-suite-master.
You can run basic-suite-master with a different data center and cluster
version manually on your computer by setting OST_DC_VERSION environment
variable, e.g.:
export OST_DC_VERSION=4.1
./run_suite.sh basic-suite-master
Barak, it's currently possible to request OST run on Gerrit patches.
I was asked whether it is also possible to request an OST run with a
non-default cluster version(s). Is it or not?
Thanks,
Milan

May snapshot status be `OK' before snapshot creation finishes?
by Milan Zamazal
Hi, a failure of previewing a snapshot with memory has been experienced
in OST master suite and I'm not sure whether REST API responses about
snapshot status are correct or not.
When I'm creating a snapshot with memory, <snapshot_status> reported
from Engine REST API in /api/vms/…/snapshots is initially `locked' and
later switches to `ok'. The problem is that `ok' starts being reported
before snapshot creation completes, resulting in errors if I try to stop
the VM or to preview the snapshot at the moment.
Does <snapshot_status>ok</snapshot_status> guarantee that the snapshot
is completed or not? I can see the following example in
ovirt-engine-sdk (for snapshot without memory):
# 'Waiting for Snapshot creation to finish'
snapshot_service = snapshots_service.snapshot_service(snapshot.id)
while True:
time.sleep(5)
snapshot = snapshot_service.get()
if snapshot.snapshot_status == types.SnapshotStatus.OK:
break
So I suppose snapshot status shouldn't switch to OK before snapshot
creation finishes. But it's not true in Engine master. Is it a bug or
a feature?
Thanks,
Milan
