Sampling threads reduction
by Francesco Romani 23 Jun '14

23 Jun '14

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-concurre…) 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/2b4c96f9ca3566f0c2f1426beff4400d5311… 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!

Re: [ovirt-devel] [oVirt 3.5 Localization Question #8] "moveDisplayNetworkWarning"
by Yevgeny Zaspitsky 22 Jun '14

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.

design flaw in ovirt
by Sven Kieske 20 Jun '14

20 Jun '14

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. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

For those of you with memberships to Stack Overflow, the site is hosting free vote-based advertisements for getting contributors for open source projects. The program will feed live remnant ads on Stack Overflow if an ad gets enough votes. oVirt has had an ad created [1] (thanks to Tuomas Kuosmanen!) that can be voted on by Stack Overflow members. For fairness' sake, feel free to vote for any of the other projects you like [2]. I would also like to thank Allon Mureinik for pointing out this opportunity and using his Stack Overflow credentials to get the ad posted! Peace, Brian [1] http://meta.stackoverflow.com/questions/260377/open-source-advertising-side… [2] http://meta.stackoverflow.com/questions/260377/open-source-advertising-side… -- Brian Proffitt oVirt Community Manager Project Atomic Community Lead Open Source and Standards, Red Hat - http://community.redhat.com Phone: +1 574 383 9BKP IRC: bkp @ OFTC

GWT/Frontent - Looking for convinient way to seperate the "data" from "presentation" in combo boxes
by Yair Zaslavsky 20 Jun '14

20 Jun '14

HI all, If you look at this link - http://www.w3schools.com/tags/tag_select.asp It shows a selection in which you have a differentiation between the displayable value, and the "data" value (which will be sent as the "selected value"). How can I do the same in GWT? At ListModel for example I saw methods only to add items. Thanks, Yair
