[Engine-devel] Monitor host's Default Gateway
by avi tal 28 Mar '12

28 Mar '12

Hi, Detach host's interface that holds the Default Gateway would be very dangerous. there for Engine must start monitor who holds the default gateway. It is true, a static IP interface can never add gateway (other than mgmt) due to CanDoAction but what about DHCP? If a non-mgmt interface with DHCP got the gateway, Engine must know about it in order to protect connectivity to the host. BTW, VDSM send these details in getCapabilities. Bottom line, we should not limit other interfaces from holding gateway, not by statically or dhcp configuration. there is a reason why someone would like to have his gateway on a different interface than the mgmt. But non-mgmt interface that holds the gateway should be treated as mgmt interface when trying to remove or edit it. Thanks

[Engine-devel] Engine meeting

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi: I just learned that this team's open project meeting is held as a teleconference. Would you consider switching it to a regular IRC meeting, perhaps with an occasional phone call? IRC meetings have many advantages in an open project: low barrier of access, easier to understand for non-native speakers, meeting log is archivable and searchable, and more inviting for the project. For phone meetings, do you publish the audio recording? That is not optimal, but at least it allows for someone to transcribe the discussion.

[Engine-devel] How to utilize Jenkins to do your dirty (build) work for you...
by Mike Kolesnik 27 Mar '12

--=_d543864b-a903-4efd-9bb5-a1966dfe6475 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, -- Intro -- When working on your local GIT repo you probably do a lot of: mvn clean install Additionally, if you're working on oVirt-engine you might be doing some of: mvn test -Penable-dao-tests mvn install -Pgwt-admin etc.. This, of course, might take your development computer a while, and hog your resources. Usually though, if you work on oVirt, you have a host that you use for testing your changes.. This host probably has a 2/4 cores CPU and at least 4Gb of RAM.. This host is sitting quietly most of the time, consuming mostly electricity but not doing much. You're probably not even utilizing it that much even when you are testing something on it. It is like a powerful guard dog that you keep tied in the back-yard most of the time, instead of letting it run free. Well, I have a suggestion how to put that puppy into good use and also free up your resources.. -- End Intro -- You can install Jenkins on the host, and have it monitor your local GIT repo for changes, building your commits as necessary. This works with every local branch you have - Jenkins will pick up the change (be it a local commit you just did, or a rebase over the origin) and generate a build for it. This will allow you to monitor your build results just as you would monitor locally, while in the same time utilize a (probably) more powerful machine to do this for you. It will also probably speed up your build cycle, as builds will be executed in parallel. I have written an installation guide which explains how to do it in the oVirt wiki: http://www.ovirt.org/wiki/Local_Jenkins_For_The_People I have also written a script that will run the installation part on the host for you, so you just need to download the attachment and run it as root on the host, but you will still need to do some manual work so make sure to check the wiki. -- Example Jobs -- I am also attaching sample jobs to import to Jenkins. Make sure to replace the GIT repo URL, you can do this before importing with sed: # sed -i 's#[git-repo-url]#ssh://[user]@[git-host]/[git-repo-location]#' oVirt-engine.* For example: # sed -i 's#[git-repo-url]#ssh://mkolesni@myhost/~/git/ovirt-engine#' oVirt-engine.* You can import them with the command: # cat [job].xml | java -jar /tmp/jenkins-cli.jar -s http://localhost:8080 create-job [job-name] For example: # cat oVirt-engine.xml | java -jar /tmp/jenkins-cli.jar -s http://localhost:8080 create-job oVirt-engine -- End Example Jobs -- Of course, this might not be ideal in cases when you need 100% percent of your host.. But in such a case you can simply turn off Jenkins, and turn it back on later. ;) Regards, Mike --=_d543864b-a903-4efd-9bb5-a1966dfe6475 Content-Type: application/x-shellscript; name=jenkins.sh

[Engine-devel] Extend host_nics action with UpdateNetworks

This is a multi-part message in MIME format. --------------040202050707070305020800 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi, I am checking the SetupNetwork feature in 3.1 (si01) and I think we are missing a very important implementation. SetupNetworks in vdsm layer is able to receive a nics collection which describe which nics will be updated and handle only those nics. This implementation is missing from engine-backend because backend automatically treat missing nics as nics we would like to remove. A very buggy scenario would be, missing mgmt network. The idea is to send (via REST API) a collection which contain only the interfaces (nics) we would like to update. This is actually an UPDATE collection procedure. it could be added as a different action: http://engine ip:port/hosts/id/nics/*updatenetworks* I believe it is a part of the SetupNetwork feature that needs to be in 3.1. Thanks --------------040202050707070305020800 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi, I am checking the SetupNetwork feature in 3.1 (si01) and I think we are missing a very important implementation.

[Engine-devel] Bridgeless Networks api design
by Michael Pasternak 26 Mar '12

26 Mar '12

Hi, First of all i would like to understand the exact meaning of the vm_network, from the wiki [1] - "a "Vm network" is implemented over a bridge, otherwise bridgeless", if so, why not calling network property <bridged>true|false</bridged>? from the other hand i understand that this is only current implementation and it may change in a future, anyway adding <vm_network>true|false</vm_network> property to <network> entity in api (as was suggested) doesn't sound good cause vm_network sounds as a network type, but then the question is Management/Migration/Storage/Display should be also network's types? and if single network can be used for the Management|Migration|Storage|Display simultaneously? if the answer is yes, network modelling probably should look like: <network> <bridged>true|false</bridged> <type>Management/Migration/Storage/Display</type> </network> or <network> <bridged>true|false</bridged> <designation>Management|Migration|Storage|Display</designation> </network> your thoughts?
