[Engine-devel] VM Payload feature
by Oved Ourfalli 10 Apr '12

10 Apr '12

Hey all, Continuing the discussion about Aeolus instance data injection to a VM (http://lists.ovirt.org/pipermail/engine-devel/2012-January/000423.html) we propose a new VM Payload feature. The following wiki page contains a description page of the feature. http://www.ovirt.org/wiki/Features/VMPayload Please read and review. There are several approaches there, and we wish to head your opinions and thoughts about them. Once we agree on an approach, we will start designing. Thank you, Oved

[Engine-devel] Moving to Jboss AS7
by Oved Ourfalli 06 Feb '12

06 Feb '12

Hey all, The code changes required to make the engine work on Jboss AS7 will soon be push It will, of course, require you to install it, and start working with it :-) A separate E-mail will be sent to notify you all once pushed, and then you'll have to perform the following steps: 1. Download jboss 7.1.0 Beta1b (http://download.jboss.org/jbossas/7.1/jboss-as-7.1.0.Beta1b/jboss-as-7.1.0.…) - There is a newer version, but it has issues in the REST-API, so we decided to work with the beta version until a proper fix will be released. 2. Fetch the latest changes from our git repository 3. Change the Jboss home to the new path, both in the JBOSS_HOME environment variable, and in maven settings file (~/.m2/settings.xml) 4. Build the engine, with profiles "dep" and "setup". This will put all the proper configuration files, postgresql driver and make all the other needed changes in Jboss in order to make it work properly mvn clean install -Psetup,dep ....... 5. In order to run Jboss go to JBOSS_HOME/bin and run ./standalone.sh 6. Look inside the JBOSS_HOME/bin/standalone.conf file in order to enable jboss debugging (just uncomment the line JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n") 7. If you have a krb5.conf file you are working with, put it in JBOSS_HOME/standalone/configuration directory 8. Run Jboss (and be impressed by the startup speed!) The above will be also added to the wiki page for building the engine as soon as the patches will be pushed upstream. Some facts about Jboss 7: 1. It supports both standalone deployment, and domain deployment. We use the standalone one. 2. Stuff related to the standalone mode can be found in the JBOSS_HOME/standalone directory: * configuration - contains the main configuration file called standalone.xml file, plus some other configuration files * deployments - that's where your deployments should be. When adding a new one, don't forget to create a file called "<deployment-name>.dodeploy" in order to make it deploy. * log - that's where the log files are written (unless stated differently in the standalone.xml file). 3. The different modules that come with Jboss 7 are located in JBOSS_HOME/modules directory * No more common/lib directory. * Every module has a module.xml file which contains it's dependencies in other modules, the jars that are part of the module, and etc. * In order to use a dependency from there you have to add "Dependencies" section to your manifest file (do git grep "Dependencies" to take a look at some examples done in the engine source code). 4. Useful links: * Documentation - https://docs.jboss.org/author/display/AS7/Documentation * Class loading changes - https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7 * The Jboss community - http://community.jboss.org/wiki Please send issues/feedback to this mailing list. Thank you all, Oved

[Engine-devel] Simplifying our POJOs
by Mike Kolesnik 06 Feb '12

06 Feb '12

--=_fc18606d-6d0a-46bb-9d9b-34be55a9dcf7 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi, Today many POJO s are used throughout the system to convey data: =E2=80=A2 Parameters - To send data to commands. =E2=80=A2 Business Entities - To transfer data in the parameters & to/f= rom the DB. These POJOs are (usually) very verbose and full of boilerplate code . This, in turn, reduces their readability and maintainability for a couple o= f reasons (that I can think of): =E2=80=A2 It's hard to know what does what: =E2=80=A2 Who participates in equals/hashCode? =E2=80=A2 What fields are printed in toString? =E2=80=A2 Consistency is problematic: =E2=80=A2 A field may be part of equals but not hashCode, or vice v= ersa. =E2=80=A2 This breaks the Object.hashCode() contract! =E2=80=A2 Adding/Removing fields take more time since you need to synchronize the cha= nge to all boilerplate methods. =E2=80=A2 Again, we're facing the consistency problem. =E2=80=A2 These simple classes tend to be very long and not very readable. =E2= =80=A2 Boilerplate code makes it harder to find out which methods don't beh= ave the default way. =E2=80=A2 Javadoc, if existent, is usually meaningless (but you might s= ee some banal documentation that doesn't add any real value). =E2=80=A2 Our existing classes are not up to standard! So what can be done to remedy the situation? We could, of course, try to simplify the classes as much as we can and mayb= e address some of the issues. This won't alleviate the boilerplate code problem altogether, though. We could write annotations to do some of the things for us automatically. The easiest approach would be runtime-based, and would hinder performance. = This also means we need to maintain this "infrastructure" and all the impli= cations of such a decision. Luckily, there is a much easier solution: Someone else already did it! Check out Project Lombok: http://projectlombok.org What Lombok gives us, among some other things, is a way to greatly simplify= our POJOs by using annotations to get the boilerplate code automatically g= enerated. This means we get the benefit of annotations which would simplify the code = a whole lot, while not imposing a performance cost (since the boilerplate c= ode is generated during compilation). However, it's also possible to create the methods yourself if you want them= to behave differently. Outside the POJO itself, you would see it as you would always see it. So what are the downsides to this approach? =E2=80=A2 First of all, Lombok provides also some other capabilities wh= ich I'm not sure are required/wanted at this time. =E2=80=A2 That's why I propose we use it for commons project, and m= ake use of it's POJO-related annotations ONLY. =E2=80=A2 There might be a problem debugging the code since it's auto-generated. =E2=80=A2 I think this is rather negligible, since usually you don'= t debug POJOs anyway. =E2=80=A2 There might be a problem if the auto-generated code throws an Exception. =E2=80=A2 As before, I'm rather sure this is an edge-case which we = usually won't hit (if at all). Even given these possible downsides, I think that we would benefit greatly = if we would introduce this library. If you have any questions, you're welcome to study out the project site whi= ch has very thorough documentation: http://projectlombok.org Your thoughts on the matter?

[Engine-devel] ovirt core MOM
by Livnat Peer 01 Feb '12

01 Feb '12

Hi All, This is what we've discussed in the meeting today: Multiple storage domain: - Should have a single generic verb for removing a disk. - We block removing the last template disk - template is immutable. - We add a shared logic for multiple actions of cloning a disk. Clone VM from Snapshot: - Shared disk and direct LUN are open issues, Yair will start a discussion on this upstream. - The suggestion was to mark direct LUN and shared disk as unplugged disks when taking a snapshot. - We had no time to discuss setup networks and stable device addressed, we'll discuss this on the next meeting. Thanks, Livnat

[Engine-devel] Quota feature design changes
by Maor 31 Jan '12

31 Jan '12

Hi all, Few changes were made in the quota design, Main issues that were changed : 1.Quota usages will be calculated and fetched using DB function instead using persistency. Using memory should improve performance and prevent integrity issues. 2.Default unlimited quota will be assigned with resources only when DC is at disable mode, in any other DC mode, user should not notice it as a consumable quota or consume new resources from it. You can view quota changes in the following design wiki: http://www.ovirt.org/wiki/Features/Design/Quota Thanks, Maor

[Engine-devel] better gwt compile times
by Gilad Chaplik 29 Jan '12

29 Jan '12

Use draftCompile flag: Enable faster, but less-optimized, compilations. draft compile only for gecko: -Dgwt.userAgent=gecko1_8 -Dgwt.draftCompile=true, Total time: 2:10.928s (3:05s without it) Saves a cool one minute (more time to be stuck in traffic) *obviously gwt developers should test their code fully compiled (for all browsers and without drafCompile flag) Thanks, Gilad.

[Engine-devel] [RFC] New Connection Management API
by Saggi Mizrahi 29 Jan '12

29 Jan '12

I have begun work at changing how API clients can control storage connections when interacting with VDSM. Currently there are 2 API calls: connectStorageServer() - Will connect to the storage target if the host is not already connected to it. disconnectStorageServer() - Will disconnect from the storage target if the host is connected to it. This API is very simple but is inappropriate when multiple clients and flows try to access the same storage. This is currently solved by trying to synchronize things inside rhevm. This is hard and convoluted. It also brings out issues with other clients using the VDSM API. Another problem is error recovery. Currently ovirt-engine(OE) has no way of monitoring the connections on all the hosts an if a connection disappears it's OE's responsibility to reconnect. I suggest a different concept where VDSM 'manages' the connections. VDSM receives a manage request with the connection information and from that point forward VDSM will try to keep this connection alive. If the connection fails VDSM will automatically try and recover. Every manage request will also have a connection ID(CID). This CID will be used when the same client asks to unamange the connection. When multiple requests for manage are received to the same connection they all have to have their own unique CID. By internally mapping CIDs to actual connections VDSM can properly disconnect when no CID is addressing the connection. This allows each client and even each flow to have it's own CID effectively eliminating connect\disconnect races. The change from (dis)connect to (un)manage also changes the semantics of the calls significantly. Whereas connectStorageServer would have returned when the storage is either connected or failed to connect, manageStorageServer will return once VDSM registered the CID. This means that the connection might not be active immediately as the VDSM tries to connect. The connection might remain down for a long time if the storage target is down or is having issues. This allows for VDSM to receive the manage request even if the storage is having issues and recover as soon as it's operational without user intervention. In order for the client to query the current state of the connections I propose getStorageConnectionList(). This will return a mapping of CID to connection status. The status contains the connection info (excluding credentials), whether the connection is active, whether the connection is managed (unamanged connection are returned with transient IDs), and, if the connection is down, the last error information. The same actual connection can return multiple times, once for each CID. For cases where an operation requires a connection to be active a user can poll the status of the CID. The user can then choose to poll for a certain amount of time or until an error appears in the error field of the status. This will give you either a timeout or a "try once" semantic depending on the flows needs. All connections that have been managed persist VDSM restart and will be managed until a corresponding unmanage command has been issued. There is no concept of temporary connections as "temporary" is flow dependent and VDSM can't accommodate all interpretation of "temporary". An ad-hoc mechanism can be build using the CID field. For instance a client can manage a connection with "ENGINE_FLOW101_CON1". If the flow got interrupted the client can clean all IDs with certain flow IDs. I think this API gives safety, robustness, and implementation freedom. Nitty Gritty: manageStorageServer =================== Synopsis: manageStorageServer(uri, connectionID): Parameters: uri - a uri pointing to a storage target (eg: nfs://server:export, iscsi://host/iqn;portal=1) connectionID - string with any char except "/". Description: Tells VDSM to start managing the connection. From this moment on VDSM will try and have the connection available when needed. VDSM will monitor the connection and will automatically reconnect on failure. Returns: Success code if VDSM was able to manage the connection. It usually just verifies that the arguments are sane and that the CID is not already in use. This doesn't mean the host is connected. ---- unmanageStorageServer ===================== Synopsis: unmanageStorageServer(connectionID): Parameters: connectionID - string with any char except "/". Descriptions: Tells VDSM to stop managing the connection. VDSM will try and disconnect for the storage target if this is the last CID referencing the storage connection. Returns: Success code if VDSM was able to unmanage the connection. It will return an error if the CID is not registered with VDSM. Disconnect failures are not reported. Active unmanaged connections can be tracked with getStorageServerList() ---- getStorageServerList ==================== Synopsis: getStorageServerList() Description: Will return list of all managed and unmanaged connections. Unmanaged connections have temporary IDs and are not guaranteed to be consistent across calls. Results:VDSM was able to manage the connection. It usually just verifies that the arguments are sane and that the CID is not already in use. This doesn't mean the host is connected. ---- unmanageStorageServer ===================== Synopsis: unmanageStorageServer(connectionID): Parameters: connectionID - string with any char except "/". Descriptions: Tells VDSM to stop managing the connection. VDSM will try and disconnect for the storage target if this is the last CID referencing the storage connection. Returns: Success code if VDSM was able to unmanage the connection. It will return an error if the CID is not registered with VDSM. Disconnect failures are not reported. Active unmanaged connections can be tracked with getStorageServerList() ---- getStorageServerList ==================== Synopsis: getStorageServerList() Description: Will return list of all managed and unmanaged connections. Unmanaged connections have temporary IDs and are not guaranteed to be consistent across calls. Results: A mapping between CIDs and the status. example return value (Actual key names may differ) {'conA': {'connected': True, 'managed': True, 'lastError': 0, 'connectionInfo': { 'remotePath': 'server:/export 'retrans': 3 'version': 4 }} 'iscsi_session_34': {'connected': False, 'managed': False, 'lastError': 339, 'connectionIfno': { 'hostname': 'dandylopn' 'portal': 1}} }

Hi all, When you introduce new business entities + DAOs or change some behaviour of existing ones, besides providing tests, please try as much as possible to insert reasonable test data to fixtures.xml, as we use the same fixtures.xml file for all our DAO testing. Kind regards, Yair

[Engine-devel] engine-core redundant instantiation of mappers
by Yair Zaslavsky 24 Jan '12

24 Jan '12

Hi all, I am refactoring now DiskImageDAODbFacadeImpl. As part of my work, I'm also defining there a Spring-JDBC mapper , similar to other ParameterizedRowMapper based mappers we have in code (i.e DbUserDAODbFacadeImpl has one) Looks like in our DAO getXXXX methods we instantiate these mapper objects (each method creates a new mapper object). Can anyone see a reason , in case a mapper object is stateless (and from what I see, they are) - why not to have a single instantiation per mapper type (i.e - Have a MapperUtils class, with static methods like MapperUtils.getDiskImageMapper() ? IMHO this can save us some unnecessary instanatiations and improve performance Yair

[Engine-devel] Engine UI only: cleaning EAR from deployment folder may be required.
by Asaf Shakarchi 23 Jan '12

23 Jan '12

Hello, Some maven re-factoring (for UI modules only) patch (http://gerrit.ovirt.org/#change,689) has just merged, You may encounter weird UI behaviours that might occur because some unnecessary data still exist in the deployed EAR folder. If so please follow these steps: 1) Clean then build (the entire engine) with Pgwt-admin,gwt-user profiles 2) Fully remove the ovirt.ear from your JBOSS deployment folder. 3) cd OVIRT_ENGINE/ear then 'mvn install -Pdep' Thanks, Regards, Asaf

[Engine-devel] Question about CloneVMFromSnapshot feature in context of shared disks and direct LUNs-based disks
by Yair Zaslavsky 22 Jan '12

22 Jan '12

Hi all, Following the upstream meeting dated Wednesday January 18th, 2012 - I presented the clone VM from snpashot feature and we discussed the feature behaviour. Two issues that were raised are the behaviour of the feature in context of shared disks and direct LUNs-based disks - On one hand, if we copy&collapse such images - this may yield to data corruption (think of a scenario where the source and destination VMs use the same disk). On the other hand - if we decide not to copy&collapse - the target VM will have missing VM and its state will not totally reflect the logical state. One of the solution raises is to mark such disks (at the destination) as unplugged, allowing the administrator the ability to plug them (understanding of course the consequences). I would like to receive inputs on this issue Kind regards, Yair

[Engine-devel] getDeviceList should report partioned devices, too
by Dan Kenigsberg 22 Jan '12

22 Jan '12

Hi Lists, One cannot create a PV on a partitioned device, and therefor such devices where not reported to Engine. This proved surprising to users who woder where their LUN disappeared. Vdsm should report all devices, and ovirt-engine should mark partitioned devices as unworthy of a PV. In the future, Vdsm may allow to forcefully remove a partition table from a device, to make it usable as a PV. Douglas (CCed) would take resposibilty on the Vdsm side. Initial patch at http://gerrit.ovirt.org/944 sports a backword-compatible API. Who's taking this on Engine? This involves GUI, too, as partitioned devices should probably be displayed greyed-out. Dan.

[Engine-devel] backup/restore your git branch out of git repository
by Eli Mesika 22 Jan '12

22 Jan '12

Hi I had last week a corrupted git repository caused possibly by a forced shutdown, I had to re-clone my repository to a new place and apply all my changes. Lucky me , I had a backup out of the git repository. The following takes 1 min to apply and may save you lot of work in case something gone wrong. The following command will create a directory named as your current git branch under ~/backup/patch and will backup there all your branch work copy the following lines to your ~/.bashrc alias gitbackup='br=$(git symbolic-ref HEAD 2>/dev/null | cut -d "/" -f3);rm -f *.patch;git format-patch origin/master;mkdir -p ~/backup/patch/$br;mv *.patch ~/backup/patch/$br' alias gitrestore='br=$(git symbolic-ref HEAD 2>/dev/null | cut -d "/" -f3);git stash; git checkout master;git checkout -b "$br-restore-$(date "+%d-%m-%y--%H-%M")";cp ~/backup/patch/$br/*.patch .;for f in $(ls -1 *.patch) ;do git am --ignore-whitespace $f;done' > source ~/.bashrc to backup your branch just run from your current git branch > gitbackup In any case you have messed up with your branch (and you have a backup), you can run from your current git branch > gitrestore this will create a new restored branch named <your-original-branch-name>-restore-<date> and apply on it your backed up patches.

[Engine-devel] Jenkins Continuous Integration Server for oVirt is up and running!
by Eyal Edri 19 Jan '12

19 Jan '12

fyi, oVirt project now has a Jenkins CI server[1] on http://jenkins.ovirt.org. The CI server runs various jobs on oVirt components *[2] such as ovirt-engine,ovirt-node,etc.. Every commit to gerrit.ovirt.org will trigger the job 'ovirt_engine' which will run 'maven' build and verify that the commit didn't break the code. If the commit did break the code, it will send an alert email to "engine-patches.ovirt.org" and to the commiter with a link to a log console containing the error. On success, the job will trigger other jobs such as "find_bugs", "gwt profiles", "create db", "unit-tests", each testing a different part of the code. In time, more and more jobs will be added to jenkins, which will allow us to catch bugs much faster than before, and to improve code quality even more. If you have questions, don't hesitate to ask me or infra(a)ovirt.org. [1] http://jenkins-ci.org/ [2] currently only ovirt-engine is configured and working. Eyal Edri oVirt infrastructure team
