If the above repository is now required in order to deploy hosts, please send a patch to ovirt-release project and/or open a BZ to be sure we enable
that repository by default.

Re: [ovirt-devel] F20 python 2.7.5-12 breaks cpopen

It's a bit confusing, but this is not a task for infra@ovirt, but for
the the similarly-named but utterly different team of ovirt developers,
who prefer patches to be sent as pull requests to
https://github.com/ovirt-infra/cpopen

Sampling threads reduction
by Francesco Romani
Hi everyone,
Over the last few days I've been working on an concept to reduce the number
of threads in VDSM. Currently, one of the biggest source of them is the VM statistics sampling:
We have one thread per VM in charge to do so, and this is obviously poorly scalable.
I tried for quite some time to solve this at libvirt level, but according to my findings and
feelings, that whould require a huge patch.
In the process of studying libvirt, I came up with a simple idea which, according to the
initial tests, seems to work quite nicely and I'd like to discuss.
The concept is to start with a thread pool (http://en.wikipedia.org/wiki/Thread_pool)
and to add the few additions needed by VDSM:
1. to detect and take care of 'stuck' tasks
2. to avoid a 'stuck' task deplenish the worker pool
3. to avoid to start leak threads on a 'stuck' task
I failed to find an existing thread pool which had those additions, so I wrote a new
one from scratch: https://github.com/mojaves/vdsm/tree/master/lib/threadpool
Then I spawned a new subpackage (a-la zombiereaper) and I consolidated the existed thread pool
(from the storage subsystem) and added some longer doc. Please note that the storage
had no changes except the trivial import fixes.
Lastly, I've also added a small compatibility module for concurrent.futures, which is a very
nice python module which provides a convenient interface to asynchronously execute callables;
this module is included in python 3.2 (https://docs.python.org/3.3/library/concurrent.futures.html#module-concur...)
and there is a backport for python 2.x. This can also allow us (as in the virt group)
to consolidate all the long running async operations using the same interface and code.
Please note that I reimplemented a thread pool mostly to be able to experiment with
the concepts listed above, which I failed to find implemented elsewhere in existing packages.
I'm fine to see them reimplemented elsewhere, since I now believe they collectively provide
a viable solution for us.
The vdsm/virt/sampling.py has been my testbed, and the patch came up nice
This is the bulk of the work
https://github.com/mojaves/vdsm/commit/2b4c96f9ca3566f0c2f1426beff4400d53...
Here all the changes, most of them are small adjustements
https://github.com/mojaves/vdsm/commits/master/vdsm/virt/sampling.py
and here is how it will looks like
https://github.com/mojaves/vdsm/blob/master/vdsm/virt/sampling.py
I'd like the sampling thread mess sorted out in time for 3.6, so please share
your thoughts!
Thanks and best regards,

Re: [ovirt-devel] [oVirt 3.5 Localization Question #8] "moveDisplayNetworkWarning"
by Yevgeny Zaspitsky
networkOperationMessage is built dynamically in the run-time (e.g. "Attach <NetworkName> to <InterfaceName>"). The final message depends on operation type and its argument(s) (1 or 2).
The possible networkOperationMessage does not include '.' (dot sign) at the end so that was added in order to separate the warning from the operation description.
Regards,
Yevgeny

[oVirt 3.5 Localization Question #2] "Update display network on cluster with an active VM" (audit log)

Hello again.
I would like to ask another question with the following details:
*File:***LocalizedEnums*
**Resource ID:***
AuditLogType___NETWORK_UPDATE_DISPLAY_FOR_CLUSTER_WITH_ACTIVE_VM*
**Strings:*** Update display network on cluster with an active VM
*Question:* Is this string an instruction to the user to update the
display network? Since the resource ID suggests it is audit log, there
might be a possibility that it is actually meant to be a past event
(i.e. "Updated").
Kind regards,
Yuko

design flaw in ovirt
by Sven Kieske
Hi,
please consider this bugreport:
https://bugzilla.redhat.com/show_bug.cgi?id=1111520
it is about the default fencing behaviour of ovirt
in the special case of a single node cluster when
a logical network marked as "required" is not available
on the single host in the cluster.
the default behaviour is, to shutdown all vms.
You can find reasoning in the BZ why this is, well,
"bad", to say the least.
Thanks in advance.
