I saw follow hints, but still don't know how to fix it. OS is fedora 19 both for node and engine, anyone can help me? Host *** does not comply with the cluster *** emulated machines. The Hosts emulated machines are clipper,none and the cluster is [rhel6.4.0, pc-1.0]} Best Regards, Dave Chen ------=_NextPart_000_0063_01CE8F8D.53576440 Content-Type: application/pkcs7-signature;

[Engine-devel] Java Newbie: Renaming some functions to fix findbugs warnings
by Adam Litke 22 Nov '13

22 Nov '13

Hello, I am working on resolving some warnings produced by findbugs and am looking for some advice on how to properly resolve the problem. The Frontend class has several pairs of methods where a capitalized version is a deprecated static form and the camelCase version is the instance method. For example: @Deprecated public static void RunQuery(...) - and - public void runQuery(...) In both cases the parameters are the same so simply renaming RunQuery to runQuery will result in a conflict. Since I am new to Java and the ovirt-engine project I am looking for some advice on how to fix the function name without breaking the code or people's sense of aesthetics. Since this is a deprecated function, would it be terrible to rename it to 'runQueryStatic' or 'runQueryDeprecated'? Since the language provides syntactic annotations for 'static' and 'deprecated', both of these names feel dirty but I am not sure what would be better. Thanks for helping out a newbie! --Adam

[Engine-devel] Fwd: Custom properties per device + vNIC profile = not working (< 3.3)

The idea behind the version splitting was: 1) We have a device with a feature that doesn't work correctly with version 3.3, but it's fixed in 3.4 2) By specifying custom property per version we cane disable this feature for 3.3 and enable for 3.4 > The custom properties are extensions which might or might not be available to > a certain VM, I don't see how having different sets of custom properties per > version (what version, DC version, cluster version?) would make any > difference - either the VM can utilize the extension given some state of the > system, or it can't, but the determining factor is not the version but > rather the availability of the extension. > For example, I can have a hook for vNIC altering some property installed on > host A and not host B, if the VM runs on host A it will get this capability > and on host B it won't, regardless the DC version the VM is in. > > This is not to say we shouldn't block custom properties on the engine-VDSM > API level since it's only available since 3.3, but this is handled by > another config value (SupportCustomDeviceProperties) which is not alterable > by the user. > So basically, I think splitting the value per version is over complication > and see no added value to the users, just more maintenance should they > choose to use this feature. > > Your thoughts please. AFAIK only network and storage team wanted to use device custom properties in 3.3 version, but I'm not sure what's current usage status. But IMHO it's too late for 3.3 to change specification ...

[Engine-devel] Problem building 3.3.1 branch
by Bob Doolittle 21 Nov '13

21 Nov '13

Hi, I'm trying to build engine for the first time and running into a build error. I'm a seasoned Unix developer, but new to some aspects of Linux development like git and maven, so I could be doing something naive. I'm following the instructions here: http://www.ovirt.org/OVirt_Engine_Development_Environment I did a clone of the engine repository, and did "git checkout -b myengine origin/ovirt-engine-3.3.1" to create my own branch based on 3.3.1 (current - I realize it's not quite done). Then, when I did "make install-dev PREFIX=$HOME/ovirt-engine" it failed when building the "Engine Web Root", specifically in the FileServletTest. Relevant build log is here: http://pastebin.com/JRcyWvtr Can anyone suggest what I've done wrong, or whether there's a problem with the repository at the moment? I'd appreciate any guidance. Thanks, Bob

[Engine-devel] Things to be done to support Ubuntu hosts
by Zhou Zheng Sheng 20 Nov '13

20 Nov '13

Hi, Recently Ubuntu support is added to VDSM, and .deb binray packages can be downloaded from launchpad.net PPA [1]. Most of the key features such as storage management and VM lifecycle work on Ubuntu. The cross distribution network management patches are upstream as well. One big piece left is making ovirt-host-deploy support Ubuntu, so that we can manage Ubuntu hosts from Engine, thus close the gap on host side. In May 2013 I made some hacks to ovirt-host-deploy and otopi. I made it skipped parts not supported on Ubuntu and configure the environment manually, and successfully added Ubuntu host to Engine [2]. Unfortunately I have no plans to continue on it, but I'd like to make a summary of the things I hacked to help anyone who wants to submit patches in future. I was to add a WIKI page but I found there were not many items, so a mail would be enough. 1. Package management operations Both otopi and ovirt-host-deploy query for dependency packages and install them on demand. The otopi package management just supports yum, we need to add apt-get support. Package names are different in Ubuntu, so I made a list mapping the names. The list in in VDSM source directory, debian/dependencyMap.txt . 2. Network configuration operations ovirt-host-deploy asks VDSM's configNetwork.py to create bridge network. Cross distribution support patches for configNetwork.py are under review. ovirt-host-deploy supports Ubuntu bridge configuration as long as they are merged. [1] https://launchpad.net/~zhshzhou/+archive/vdsm-ubuntu [2] http://www.ovirt.org/images/5/57/Shanghai-VDSM-on-Ubuntu.pdf Here goes the detailed hack patch. The hack was base on v1.0.1, I rebased it to the latest master. The rebased patch are not tested. If you find this email useless, it's actually a good news, which means there is not a lot of work and problems ahead ;-) Hack patch for ovirt-host-deploy. >From 120493a242046d19794ef3da83b32486d372aa39 Mon Sep 17 00:00:00 2001 From: Zhou Zheng Sheng <zhshzhou(a)linux.vnet.ibm.com> Date: Wed, 13 Nov 2013 18:02:26 +0800 Subject: [PATCH] Ubuntu Hacks Change-Id: Ifb4ebc829101c92d06475619b1b5986e87b83d57 Signed-off-by: Zhou Zheng Sheng <zhshzhou(a)linux.vnet.ibm.com> --- src/plugins/ovirt-host-deploy/gluster/packages.py | 17 +++++---- src/plugins/ovirt-host-deploy/tune/tuned.py | 3 +- src/plugins/ovirt-host-deploy/vdsm/bridge.py | 45 ++++++++++++----------- src/plugins/ovirt-host-deploy/vdsm/packages.py | 9 +++-- src/plugins/ovirt-host-deploy/vdsm/pki.py | 3 +- src/plugins/ovirt-host-deploy/vdsm/software.py | 2 + src/plugins/ovirt-host-deploy/vdsm/vdsmid.py | 3 +- 7 files changed, 45 insertions(+), 37 deletions(-) diff --git a/src/plugins/ovirt-host-deploy/gluster/packages.py b/src/plugins/ovirt-host-deploy/gluster/packages.py index 1fecfda..eb37744 100644 --- a/src/plugins/ovirt-host-deploy/gluster/packages.py +++ b/src/plugins/ovirt-host-deploy/gluster/packages.py @@ -60,13 +60,13 @@ class Plugin(plugin.PluginBase): ), ) def _validation(self): -

[Engine-devel] Question about Engine user session timeout
by Vojtech Szocs 19 Nov '13

19 Nov '13

Hi guys, I see two different config values for dealing with Engine user session timeout. First, from packaging/etc/engine-config/engine-config.properties file: - UserSessionTimeOutInterval.description=Session timeout interval in minutes, after which it will be expired and clean. A negative value indicates the session should never timeout. - UserSessionTimeOutInvalidationInterval.description=Session timeout invalidation interval in minutes. Specifies the interval in which the invalidation check should occur. Then, in org.ovirt.engine.core.common.config.ConfigValues enum: - UserSessionTimeOutInterval (default 30) - UserSessionTimeOutInvalidationInterval (default 30) Looking at Backend#Initialize, both of these values are used when scheduling "cleanExpiredUsersSessions" job: - UserSessionTimeOutInterval = initialDelay param, i.e. the initial delay before the first activation [SchedulerUtil#scheduleAFixedDelayJob] - UserSessionTimeOutInvalidationInterval = taskDelay param, i.e. the delay between jobs [SchedulerUtil#scheduleAFixedDelayJob] So if I read this correctly, if UserSessionTimeOutInterval=100 then UserSessionTimeOutInvalidationInterval is relevant only after first 100min of Engine uptime. Why do we have two different config values for Engine user session timeout? i.e. why don't we use same value for both initialDelay & taskDelay param? Thanks, Vojtech

[Engine-devel] [UX] how to design a bar/line chart?
by Tomas Jelinek 18 Nov '13

18 Nov '13

Hi all, There is a feature request [1] which aims to replace the resource utilization graphs (for example the cpu utilization from vm tab) by some which shows not only the actual percentage which is not so useful by some monitor graph. I have the following concerns: - I can think of a bar chart or a line chart and not sure what would be better. - Not sure if replacing the current chart with a bar/line chart would make the statistics readable enough. Maybe if you hover the chart it could pop up a bigger version of the chart? Or not needed? - Would it be enough to have it in one color? Or should it be something like "the bigger the utilization the more red"? Please advise from the UX perspective. As soon as the final design will be a bit more clear I will provide a feature page. Thank you, Tomas [1]: https://bugzilla.redhat.com/show_bug.cgi?id=803251
