Regression in java-1.7.0-openjdk-1.7.0.65
by Martin Perina 22 Jul '14

Hi, there's some regression in java-1.7.0-openjdk-1.7.0.65 (probably this one [1]) that causes failure in our tests: Tests in error: initializationError(org.ovirt.engine.api.restapi.resource.BackendResourceInfoDetailTest): Bad <init> method call from inside of a branch Exception Details: Location: org/ovirt/engine/api/restapi/resource/AbstractBackendResourceLoggingTest.<init>(Lorg/powermock/core/IndicateReloadClass;)V @40: invokespecial Reason: Error exists in the bytecode Bytecode: 0000000: 2a2b 4e4d 1210 b800 1604 bd00 0d59 032d 0000010: 5312 a6b8 001b b800 213a 0519 05b2 0025 0000020: a500 0e2a 01c0 0027 b700 2aa7 000a 2c2d 0000030: b700 2a01 57b1 Stackmap Table: full_frame(@46,{UninitializedThis,Object[#39],UninitializedThis,Object[#39],Top,Object[#13]},{}) full_frame(@53,{Object[#2],Object[#39],Object[#2],Object[#39],Top,Object[#13]},{}) initializationError(org.ovirt.engine.api.restapi.resource.BackendResourceDebugDetailTest): Bad <init> method call from inside of a branch Exception Details: Location: org/ovirt/engine/api/restapi/resource/AbstractBackendResourceLoggingTest.<init>(Lorg/powermock/core/IndicateReloadClass;)V @40: invokespecial Reason: Error exists in the bytecode Bytecode: 0000000: 2a2b 4e4d 1210 b800 1604 bd00 0d59 032d 0000010: 5312 a6b8 001b b800 213a 0519 05b2 0025 0000020: a500 0e2a 01c0 0027 b700 2aa7 000a 2c2d 0000030: b700 2a01 57b1 Stackmap Table: full_frame(@46,{UninitializedThis,Object[#39],UninitializedThis,Object[#39],Top,Object[#13]},{}) full_frame(@53,{Object[#2],Object[#39],Object[#2],Object[#39],Top,Object[#13]},{}) If you spot this error, just downgrade to java-1.7.0-openjdk-1.7.0.60, which works fine.

[URGENT] [ACTION REQUIRED] can't build engine from ovirt-engine-3.5 branch
by Sandro Bonazzola 21 Jul '14

21 Jul '14

Hi, today we were supposed to release oVirt 3.5 beta 2. However, oVirt engine can't be built neither on master not on ovirt-engine-3.5 branch. Offending patch should be GERRIT:30122 which broke the build since last Jul 16th [1]. On master I can see some patches have been pushed / merged trying to fix that but looks like they didn't solve. So we still have some jobs still broken also on master [2][3][4]. Please either fix the issue or revert breaking patches. We're going to block the second beta release until the issue is solved. [1] http://jenkins.ovirt.org/view/Stable%20branches%20per%20project/view/ovirt-… [2] http://jenkins.ovirt.org/view/Master%20branch%20per%20project/view/ovirt-en… [3] http://jenkins.ovirt.org/view/Master%20branch%20per%20project/view/ovirt-en… [4] http://jenkins.ovirt.org/view/Master%20branch%20per%20project/view/ovirt-en… Thanks, -- Sandro Bonazzola Better technology.

Webadmin build failure on ovirt-engine master
by Moti Asayag 21 Jul '14

Hi, Building the ovirt-engine master branch fails with the following, while build the ovirt-engine-3.5 branch ended successfully. Any idea what might cause the failure ? It seems like a local issue since jenkins build passes.

postponing oVirt 3.5.0 second beta
by Sandro Bonazzola 21 Jul '14

21 Jul '14

Hi, we're going to postpone oVirt 3.5.0 second beta since ovirt-engine currently doesn't build [1]. We also have identified a set of bugs causing automated tests to fail so we're going to block the release until engine will build cleanly and at least most critical issues found have been fixed. Please note that more than 80 patches are now in master and not backported to 3.5 branch. Maintainers, please ensure all patches targeted to 3.5 are properly backported. Probably we're going to postpone second test day too, according to the date we'll be able to compose the second beta build.

Hi, we'll have 3.5 beta 2 on Monday and vdsm-jsonrpc-java is still failing to build on CentOS 6[1]. Can you please fix it? http://jenkins.ovirt.org/view/Master%20branch%20per%20project/view/vdsm-jso… We'll have second test day after this build and I guess most of the people will run CentOS / RHEL so this package must build.

[ANN] oVirt 3.4.3 Release is now available
by Sandro Bonazzola 18 Jul '14

18 Jul '14

The oVirt development team is pleased to announce the general availability of oVirt 3.4.3 as of Jul 18th 2014. This release solidifies oVirt as a leading KVM management application and open source alternative to VMware vSphere. oVirt is available now for Fedora 19 and Red Hat Enterprise Linux 6.5 (or similar). This release of oVirt includes numerous bug fixes. See the release notes [1] for a list of the new features and bugs fixed. The existing repository ovirt-3.4 has been updated for delivering this release without the need of enabling any other repository, however since we introduced package signing you need an additional step in order to get the public keys installed on your system if you're upgrading from an older release. Please refer to release notes [1] for Installation / Upgrade instructions. Please note that mirrors will need a couple of days before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.4.repo commenting the mirror line and removing the comment on baseurl line. A new oVirt Live ISO will be available too[2].

Hi, recent python upgrade in Fedora 19 broke vdsmd service. While we wait for an updated python-cpopen package to be built, we're postponing oVirt 3.4.3 GA. The package should be built for tomorrow and will be hosted on ovirt repo until it will be available on Fedora repositories. We'll release 3.4.3 after basic sanity testing with the new package.

Hi, while I was working on Bug 1097022 - ovirt-engine-setup: weak default passwords for PostgreSQL database users I was wondering where to write hardening tips described in comment #18.

[VDSM][sampling] thread pool status and handling of stuck calls
by Francesco Romani 16 Jul '14

16 Jul '14

Hi, Nir has begun reviewing my draft patches about the thread pool and sampling refactoring (thanks!), and already suggested quite some improvements which I'd like to summarize Quick links to the ongoing discussion: http://gerrit.ovirt.org/#/c/29191/8/lib/threadpool/worker.py,cm http://gerrit.ovirt.org/#/c/29190/4/lib/threadpool/README.rst,cm Quick summary of the discussion on gerrit so far: 1. extract the scheduling logic from the thread pool. Either add a separate scheduler class or let the sampling task reschedule themselves after a succesfull completion. In any way the concept of 'periodic task', and the added complexity, isn't needed. 2. drop all the *queue classes I've added, thus making the package simpler. They are no longer needed since we remove the concept of periodic task. 3. have per-task timeout, move the stuck task detection elsewhere, like in the worker thread, ot maybe better in the aforementioned scheduler. If the scheduler finds that any task started in the former pass (or even before!) has not yet completed, there is no point in keeping this task alive and it should be cancelled. 4. the sampling task (or maybe the scheduler) can be smarter and halting the sample in presence of not responding calls for a given VM, granted the VM reports its 'health'/responsiveness. (Hopefully I haven't forgot anything big) In the draft currently published, I reluctantly added the *queue classes and I agree the periodic task implementation is messy, so I'll be very happy to drop them. However, a core question still holds: what to do in presence of the stuck task? I think it is worth to discuss this topic on a medium friendlier than gerrit, as it is the single most important decision to make in the sampling refactoring. It all boils down to: Should we just keep somewhere stuck threads and wait? Should we cancel stuck tasks? A. Let's cancel the stuck tasks. If we move toward a libvirt connection pool, and we give each worker thread in the sampling pool a separate libvirt connection, hopefully read-only, then we should be able to cancel stuck task by killing the worker's libvirt connection. We'll still need a (probably much simpler) watchman/supervisor, but no big deal here. Libvirt allows to close a connection from a different thread. I haven't actually tried to unstuck a blocked thread this way, but I have no reason to believe it will not work. B. Let's keep around blocked threads The code as it is just leaves a blocked libvirt call and the worker thread that carried it frozen. The stuck worker thread can be replaced up to a cap of frozen threads. In this worst case scenario, we end up with one (blocked!) thread per VM, as it is today, and with no sampling data. I believe that #A has some drawbacks which we risk to overlook, and on the same time #B has some merits. Let me explain: The hardest case is a call blocked in the kernel in D state. Libvirt has no more room than VDSM to unblock it; and libvirt itself *has* a pool of resources (threads in this case) which can be depleted by stuck calls. Actually, retrying to do a failed task may deplete their pool even faster[1]. I'm not happy to just push this problem down the stack, as it looks to me that we gain very little by doing so. VDSM itself surely stays cleaner, but the VDS/hypervisor hosts on the whole improves just a bit: libvirt scales better, and that gives us some more room. On the other hand, by avoiding to reissue dangerous calls, I believe we make better use of the host resources in general. Actually, the point of keeping blocked thread around is a side effect of not reattempting blocked calls. Moreover, to keep the blocked thread around has a significant benefit: we can discover at the earliest moment when it is safe again to do the blocked call, because the blocked call itself returns and we can track this event! (and of course drop the now stale result). Otherwise, if we drop the connection, we'll lose this event and we have no more option that trying again and hoping for the best[2] I know the #B approach is not the cleanest, but I think it has slightly more appeal, especially on the libvirt depletion front. Thoughts and comments very welcome! +++ [1] They have extensions to management API to dinamically adjust their thread pool and/or to cancel tasks, but it is in the RHEL7.2 timeframe. [2] A crazy idea would be to do something like http://en.wikipedia.org/wiki/Exponential_backoff which I'm not sure would be beneficial Bests and thanks, -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

Custom fencing with virsh_fence
by Adam Litke 15 Jul '14

15 Jul '14

Hi all, I am trying to configure custom fencing using fence_virsh in order to test out fencing flows with my virtualized oVirt hosts. I'm getting a failure when clicking the "Test" button. Can someone help me to diagnose the problem? I have applied the following settings using engine-config: ~/ovirt-engine/bin/engine-config -s CustomVdsFenceType="xxxvirt" ~/ovirt-engine/bin/engine-config -s CustomFenceAgentMapping="xxxvirt=virsh" ~/ovirt-engine/bin/engine-config -s CustomVdsFenceOptionMapping="xxxvirt:address=ip,username=username,password=password" (note that engine-config seems to arbitrarily limit the number of mapped options to 3.

Info related to display port allocation
by Vinzenz Feenstra 15 Jul '14

15 Jul '14

Hi, I just want to give all of you an update on a recently created bug on VDSM. Until recently we had 2 ports allocated for spice one for tls and one plain text. We have now observed the behaviour on RHEL7 and I also did now on RHEL6 that when all spice channels are marked as secure, only the tlsPort value is set in the domain xml. VDSM will report the non-tls port as 'port=-1' For us this is a good thing since we're saving one port in these cases and we're encouraging users to use the ssl configuration anyway. I just wanted to give you a heads up on this, in case anyone is assuming the 'port' value reported by getAllVmStats or list full=True API calls would be returning any value but -1. -- Regards, Vinzenz Feenstra | Senior Software Engineer RedHat Engineering Virtualization R & D Phone: +420 532 294 625 IRC: vfeenstr or evilissimo Better technology.

FYI, please share some karma for this package! It seems that all host installation for ovirt fail until this is resolved, maybe there should be additional tests before releasing new software?

Removing boilerplate code in engine
by Mike Kolesnik 14 Jul '14

14 Jul '14

Hi, I recently introduced 2 changes for removing boilerplate code: 1. http://gerrit.ovirt.org/29414 - Fluent syntax for writing validations 2. http://gerrit.ovirt.org/29617 - Wrapper for locks to use with try-with-resources By removing boilerplate code we're making the code less error prone and easier to read (and maintain). I've already sent some simple refactors to use these new styles of writing, but more work is necessary to apply to the whole project. I urge all engine developers that need to write such code to use the new styles of writing. Below are examples for each change. 1. When expecting a negative outcome, instead of using: return getVds() == null ? new ValidationResult(VdcBllMessages.ACTION_TYPE_FAILED_HOST_NOT_EXIST) : ValidationResult.VALID; use: return ValidationResult.failWith(VdcBllMessages.ACTION_TYPE_FAILED_HOST_NOT_EXIST) .when(getVds() == null); When expecting a positive outcome, instead of using: return FeatureSupported.nonVmNetwork(getDataCenter().getcompatibility_version()) ? ValidationResult.VALID : new ValidationResult(VdcBllMessages.NON_VM_NETWORK_NOT_SUPPORTED_FOR_POOL_LEVEL); use: return ValidationResult.failWith(VdcBllMessages.NON_VM_NETWORK_NOT_SUPPORTED_FOR_POOL_LEVEL) .unless(FeatureSupported.nonVmNetwork(getDataCenter().getcompatibility_version())); 2. To lock a block of code, instead of using [1]: lock.lock(); try { // Thread safe code } finally { lock.unlock(); } use: try (AutoCloseableLock l = new AutoCloseableLock(lock)) { // Thread safe code } [1] This is best used with locks from java.util.concurrent.locks package. For regular thread safe blocks it's best to use the standard synchronized block. Regards, Mike

Hello everybody, Few days ago we published python-pthreading 0.1.3-2 which included a patch ([1]) that fixes urgent bug in ovirt ([2]) Today we found out that this build also includes a patch (called monkey_patch: Fail if it is too late to monkey-patch) that introduces regression with older versions of ovirt. Therefore we publish new build (0.1.3-3) that includes only the required fix. Please test and give it a karma for your environment, if you can [3] [4] [5] [6] [7] Thanks, [1] Add the missing locked() interface [2] https://bugzilla.redhat.com/show_bug.cgi?id=1117795 [3] http://koji.fedoraproject.org/koji/buildinfo?buildID=543650 (el6) [4] http://koji.fedoraproject.org/koji/buildinfo?buildID=543651 (f19) [5] http://koji.fedoraproject.org/koji/buildinfo?buildID=543653 (f20) [6] http://koji.fedoraproject.org/koji/buildinfo?buildID=543649 (f21) [7] http://koji.fedoraproject.org/koji/buildinfo?buildID=543655 (el7) -- Yaniv Bronhaim.

[IMPORTANT] DB script numbering reminder
by Oved Ourfali 13 Jul '14

13 Jul '14

Hi Now that a branch was created for ovirt-engine-3.5, master is practically of version 3.6. So, when adding a DB script in a patch that is pushed to master, the numbering should start with 03_06_ABCD, where ABCD starts with 0010, second should be 0020, and so on... When this patch needs to be ported to 3.5 as well, the numbering there should be 03_05_EFGH, where EFGH is the next number in the stable branch. So, for example, if the last upgrade script in the stable branch starts with 03_05_0750, then the next should start with 03_05_0760, even if it starts with 03_06_0040 on master. Confused? we're here to help! Got it? go ahead and push some stuff! Have a great day, Oved

ovirt-guest-agent
by Sandro Bonazzola 12 Jul '14

12 Jul '14

Hi, looking at http://jenkins.ovirt.org/view/All/ I see that for ovirt-guest-agent there's only the following job: http://jenkins.ovirt.org/view/All/job/ovirt-guest-agent_master_gerrit/ This means that ovirt-guest-agent is not built nightly neither for master nor for stable and it's not published neither in nightly snapshot nor in official releases. I see that ovirt-guest-agent is shipped within Fedora and EPEL: http://koji.fedoraproject.org/koji/packageinfo?packageID=15434 so I suppose official release are shipped there. Do we need nightly builds? Also I see that http://www.ovirt.org/How_to_install_the_guest_agent_in_Fedora refers to obsolete layout / releases and the package is not shipped within oVirt repo for above considerations and should be updated accordingly. -- Sandro Bonazzola Better technology.

[vdsm] VM recovery now depends on HSM
by Adam Litke 11 Jul '14

11 Jul '14

Hi all, As part of the new live merge feature, when vdsm starts and has to recover existing VMs, it calls VM._syncVolumeChain to ensure that vdsm's view of the volume chain matches libvirt's. This involves two kinds of operations: 1) sync VM object, 2) sync underlying storage metadata via HSM. This means that HSM must be up (and the storage domain(s) that the VM is using must be accessible. When testing some rather eccentric error flows, I am finding this to not always be the case. Is there a way to have VM recovery wait on HSM to come up? How should we respond if a required storage domain cannot be accessed? Is there a mechanism in vdsm to schedule an operation to be retried at a later time? Perhaps I could just schedule the sync and it could be retried until the required resources are available. Thanks for your insights. -- Adam Litke

[vdsm] logging levels and noise in the log
by Martin Sivak 11 Jul '14

11 Jul '14

Hi, we discussed the right amount of logging with Nir and Francesco while reviewing my patches. Francesco was against one DEBUG log message that could potentially flood the logs. But the message in question was important for me and SLA, because it was logging the VDSM changes in response to MoM command. Since DEBUG really is meant to be used for debug messages, I have one proposal: 1) Change the default log level of vdsm.log to INFO 2) Log (only) DEBUG messages to a separate file vdsm-debug.log 3) Make the vdsm-debug.log rotate faster (every hour, keep only last couple of hours?) so it does not grow too much This way the customer would be able to monitor INFO logs (much smaller) without all the noise and we would be able to collect the DEBUG part in case something happens. What do you think? -- Martin Sivák msivak(a)redhat.com Red Hat Czech RHEV-M SLA / Brno, CZ

[Documentation] Assistance Needed with User-Facing Documentation
by Brian Proffitt 10 Jul '14

10 Jul '14

All: The Red Hat ECS team has made a great effort to convert some of the more important downstream documentation to a MediaWiki format that we can post on oVirt.org as an official set of user- and admin-facing documentation. This is being done as a bootstrapping effort to get our upstream documentation up to date and take a big step towards making the upstream documentation the canonical source for documentation in the near future. Before that can happen, we need to get this RHEV-oriented information ported over to oVirt nomenclature and screenshots taken for oVirt and added to the documents as well. I have placed the three guides * Administration Guide[1] * User's Guide[2] * Installation Guide[3] on the oVirt site as unlinked pages. General wording has been changed from RHEV to oVirt, but not always. Each of these documents must be reviewed and completely adapted to oVirt 3.4 before they can be posted as official documentation. Specifically: * Review all text to ensure proper steps and descriptions for oVirt features and procedures * Review all text to remove downstream-specific text * Review all code for changes in package names on on-screen displays * Replace all downstream RHEV screenshots with upstream oVirt 3.4 screenshots (Max width: 1024px) I will be stepping through these documents to edit them in more detail under these guidelines, but help is most assuredly needed, in order to get this done in a timely manner. oVirt.org wiki users can visit these pages, review them, and add their changes. MediaWiki has limited version control, so it would be best to edit sections instead of entire documents, to minimize stepping on others' changes. Editing by section will also help us track the sections that have been edited, using the pages' histories. Thank you in advance for all of your help on this project... when finished, this will represent a significant improvement to oVirt's documentation, and make oVirt that much easier to use.

Exception during VM recovery causes VMs not being properly recovered
by Vinzenz Feenstra 10 Jul '14

10 Jul '14

Hi, With the current master of VDSM after restarting VDSM (e.g. after upgrading) I noticed that the VMs were not properly initialized and in PAUSED state. Once checking the logs I found that the cause was here: Thread-13::INFO::2014-07-10 12:11:56,400::vm::2244::vm.Vm::(_startUnderlyingVm) vmId=`db614831-3b4b-4010-a989-f7a5ae6fa5d0`::Skipping errors on recovery Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 2228, in _startUnderlyingVm self._run() File "/usr/share/vdsm/virt/vm.py", line 3312, in _run self._domDependentInit() File "/usr/share/vdsm/virt/vm.py", line 3204, in _domDependentInit self._syncVolumeChain(drive) File "/usr/share/vdsm/virt/vm.py", line 5686, in _syncVolumeChain volumes = self._driveGetActualVolumeChain(drive) File "/usr/share/vdsm/virt/vm.py", line 5665, in _driveGetActualVolumeChain sourceAttr = ('file', 'dev')[drive.blockDev] TypeError: tuple indices must be integers, not NoneType The reason here seems to be this: Thread-13::DEBUG::2014-07-10 12:11:56,393::vm::1349::vm.Vm::(blockDev) vmId=`db614831-3b4b-4010-a989-f7a5ae6fa5d0`::Unable to determine if the path '/rhev/data-center/00000002-0002-0002-0002-000000000002/41b6de4e-23da-481d-904d-9af24fc5f3ab/images/17206f99-38ab-45bc-ae9b-d36a66b00e4c/7b05de43-9d85-435f-8ae9-6ccde21548e4' is a block device Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 1346, in blockDev self._blockDev = utils.isBlockDevice(self.path) File "/usr/lib64/python2.6/site-packages/vdsm/utils.py", line 99, in isBlockDevice return stat.S_ISBLK(os.stat(path).st_mode) OSError: [Errno 2] No such file or directory: '/rhev/data-center/00000002-0002-0002-0002-000000000002/41b6de4e-23da-481d-904d-9af24fc5f3ab/images/17206f99-38ab-45bc-ae9b-d36a66b00e4c/7b05de43-9d85-435f-8ae9-6ccde21548e4' I am running the host on RHEL6.5 Note: I just rebooted the host and started a few more VMs again and when I restart VDSM I get the same errors again. -- Regards, Vinzenz Feenstra | Senior Software Engineer RedHat Engineering Virtualization R & D Phone: +420 532 294 625 IRC: vfeenstr or evilissimo Better technology.

Re: [ovirt-devel] [VDSM][sampling] thread pool status and handling of stuck calls
by Saggi Mizrahi 10 Jul '14

10 Jul '14

The more I think about it the more it looks like it's purely a libvirt issue. As long as we can make calls that get stuck on D state we can't scale under stress. In any case, seems like having an interface like. libvirtConnectionPool.request(args, callback) Would be a better solution than a thread pool. It would queue up the request and call the callback once it's done. pseudo example: def collectStats(): def callback(resp): doStuff(resp) threading.Timer(4, collectStats) lcp.listAllDevices(callback) We could have the timer queue in a threadpool since it normally runs in the main thread but that is orthogonal to the libvirt connection issue. As for the thread pool itself. As long as it's more than one class it's too complicated. Things like: * Task Cancelling * Re-queuing (periodic operations) Shouldn't be part of the thread pool. Task should just be functions. If we need something with a state we could use the __call__() method to make an object look like a function. I also don't mind doing if hasattr(task, "run") or callable(task) to handle it using an "interface" Re-queuing could be done with the build it threading.Timer as in threading.Timer(4.5, threadpool.queue, args=(self,)) That way each operation is responsible for handing the details of rescheduling. Should we always wait X, should we wait X - timeItTookToCalculate. You could also do: threading.Timer(2, threadpool.queue, args=(self,)) threading.Timer(4, self.handleBeingLate) Which would handle not getting queued for a certain amount of time. Task cancelling can't be done in a generic manner. The most I think we could do is have threadpool.stop() check hassattr("stop", task) and call it. ----- Original Message ----- > From: "Francesco Romani" <fromani(a)redhat.com> > To: devel(a)ovirt.org > Sent: Friday, July 4, 2014 5:48:59 PM > Subject: [ovirt-devel] [VDSM][sampling] thread pool status and handling of stuck calls > > Hi, > > Nir has begun reviewing my draft patches about the thread pool and sampling > refactoring (thanks!), > and already suggested quite some improvements which I'd like to summarize > > Quick links to the ongoing discussion: > http://gerrit.ovirt.org/#/c/29191/8/lib/threadpool/worker.py,cm > http://gerrit.ovirt.org/#/c/29190/4/lib/threadpool/README.rst,cm > > Quick summary of the discussion on gerrit so far: > 1. extract the scheduling logic from the thread pool.

Docker containers for ovirt-engine
by Daniel Erez 10 Jul '14

10 Jul '14

Hi, I've created a couple of Docker images with a running ovirt-engine service and uploaded to the Docker registry [1]. Quite useful for quickly having a ready-to-use environment (tests, demos, etc) or to be used as a base image for building new Docker Images. Note that currently the container is not persistent by its nature, hence for saving changes, take use of the 'commit' functionality [2].

Update on ovirt-appliance and ovirt-node-iso for oVirt 3.5
by Fabian Deutsch 10 Jul '14

10 Jul '14

Hello, I just wanted to give a short update on the state of the ovirt-appliance and ovirt-node-iso for 3.5. ovirt-node is actually in a quite good shape. An iso is available with the ovirt-node-plugin-vdsm and -hosted-engine. Both based on ovirt-node from master, which will be branched off. The pain point is the automation. Ryan has actually gotten the Jenkins job back into place - good job! - so that at least the rpm packages are built. And could actually be included in the nighlies, Sandro. The automatic iso generation is still not working, due to several reasons (same as the last N months). The appliance generation is in a slightly better state than the ovirt-node-iso generation, but is still failing when it comes to automation. The automation is currently blocked by several issues which I tried to tackle together with David during the last week. The build automation of the appliance is actually getting most of my attention these days, as it is more likely to get the automation working. So we are not stable yet, but we are moving into the right direction. Greetings fabian

VDSM sync meeting minutes July 8th, 2014
by Dan Kenigsberg 09 Jul '14

09 Jul '14

We had relatively low attendence today and we did not discuss pending 3.5 issus deeply enough. If you have urgent 3.5 issue that needs fix/review, please chime in! live-merge: - we have 2 complex patches by Adam http://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:li… jsonrpc - we have 3 pending patches by Piotr http://gerrit.ovirt.org/#/q/owner:%22Piotr+Kliczewski%22+status:open+projec… The most flaky of them adds lastClientIface element to getVdsCaps over jsonrpc. That element is used by Engine to deduce which network interface is used to carry management traffic, and build ovirtmgmt network on top of this. I suggest in Bug 1117303 - add a new getRoute() verb to introduce a new verb for this purpose, but until this happens in 3.6, we'd need a hack to expose it here. pthreading's superfluous wakeups - Nir's reported bug is still in effect, and his suggested patches awaits review. qos patches - Martin has plenty of patches. Most urgent is the log spam avoidence of http://gerrit.ovirt.org/#/c/29504/9/vdsm/virt/vm.py All should be reviewed by virt folks, due to the natural dependency. copious rebases - It is sometimes tempting to use a single topic branch for multiple patches that do not really depend on each other. The down size of this is that on every rebase, reviewers are swamped with emails; it is also less apparent that a certain patch can be merged without waiting for previous patches. So if you can break your serial branch to multiple branches with the same topic, you should probably do it. Hear you in a fortnight, Dan.
