[Engine-devel] Using REST API in web UI - review call summary
by Vojtech Szocs 14 Feb '14

14 Feb '14

Hi guys, this is a summary of yesterday's review call, I'll try to highlight important Q/A and things we agreed on. Feel free to add anything in case I've missed something. -- Q: Why don't we simply try to use existing Java SDK and adapt it for GWT apps? (asked by Michael & Gilad) A: This might be a viable option to consider if we wanted to skip JavaScript-based SDK altogether and target Java/GWT code directly; we could simply take Java SDK and customize its abstractions where necessary, i.e. using HTTP transport layer implementation that works with GWT. In any case, this would mean coupling ourselves to Java SDK (which has its own release cycle) and I think this would complicate things for us. As proposed on the meeting, I think it's best to aim for JavaScript SDK as the lowest common denominator for *any* web application that wants to work with REST API. oVirt GWT-based UI can simply bind to JavaScript SDK, i.e. Java/GWT code that just overlays objects and functions provided by JavaScript SDK. Another reason is ease of maintenance - I'd rather see JavaScript SDK's code generation process to be independent of any other SDK (people responsible for maintaining JavaScript SDK should have full control over generated code). -- Q: What about functionality currently used by oVirt UI but not supported by REST API? (asked by Einav) [For example, fetching VM entity over GWT RPC also returns related data such as Cluster name.] A: Based on discussion I've had with other colleagues after yesterday's review call, I don't think that separate support-like backend layer is a good idea. Instead, this is the kind of functionality that could be placed in oVirt.js library. Logical operations like "get VMs and related data" would be exposed through oVirt.js (callback-based) API and ultimately realized as multiple physical requests to REST API via JavaScript Binding. oVirt.js client would be completely oblivious to the fact that multiple physical requests are dispatched. In fact, since HTTP communication is asynchronous in nature, oVirt.js client wouldn't even notice any difference in terms of API consumption. This assumes JavaScript SDK would use callback-based (non-blocking) API instead of blocking one - after all, blocking API on top of non-blocking implementation sounds pretty much like leaky abstraction [1]. For example: sdk.getVmsWithExtraData( callbackToGetExtraDataForGivenVm, // might cause extra physical requests to REST API callbackFiredWhenAllDataIsReady // update client only when all data is ready ) [1] http://en.wikipedia.org/wiki/Leaky_abstraction -- Last but not least, where to maintain JavaScript SDK projects: low-level JavaScript Binding + high-level oVirt.js library. I agree that conceptually both above mentioned projects should go into dedicated "ovirt-engine-sdk-js" git repository and have their own build/release process. However, for now, we're just making baby steps so let's keep things simple and prototype these projects as part of "ovirt-engine" git repository. ... we can complicate things anytime, but we should know that any complex system that works has inevitably evolved from simple system that works ...

[Engine-devel] [ovirt-testday] Fake PPC Support - Feedback

This is a multi-part message in MIME format. --------------070509070905070907070200 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi, On the test day I was testing the Fake PPC support. I managed to register the Fake PPC host into the engine. However when I tried to run the VM it failed with libvirt responding: * libvirtError: internal error: process exited while connecting to monitor: "kvm" accelerator does not exist.** **No accelerator found!** **KVM not supported for this target** *** Which does not make much sense though. Since it should not try to use 'kvm'. And I am not really sure why it does. Please let me know if there's anything else I would need to provide you so you can figure out what is going on. Right now the server is still in the same state. But I eventually will have to use it for something else.

[Engine-devel] ovirt-engine build segfault on Fedora 20
by Greg Sheremeta 04 Feb '14

04 Feb '14

Caution on upgrading your dev machine to Fedora 20. GWT compilation of "safari" (for Chrome) causes a segfault during the build. Strangely, the build appears to work, so I'm not sure what the net effect of the segfault is. If you only compile for gecko (Firefox) [the default], you won't see the segfault. In other words, make clean install-dev PREFIX=$HOME/ovirt-engine DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8,safari" causes the segfault But make install-dev PREFIX="$HOME/ovirt-engine" works just fine. I've duplicated this with with both OpenJDK and Oracle JDK. If you'd like to duplicate, simple install a fresh F20 VM, and then run these commands: 1 sudo yum install nano 2 sudo nano /etc/hostname #set the hostname 3 sudo nano /etc/hosts #set the hostname 5 sudo yum install http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm 6 sudo yum install git java-devel maven openssl postgresql-server m2crypto python-psycopg2 python-cheetah python-daemon libxml2-python jboss-as unzip otopi 7 mkdir projects 8 cd projects/ 9 git clone git://gerrit.ovirt.org/ovirt-engine 10 cd ovirt-engine/ 11 make install-dev PREFIX="$HOME/ovirt-engine" Greg Sheremeta Red Hat, Inc.

[Engine-devel] mom RPMs for 3.4
by Adam Litke 03 Feb '14

03 Feb '14

Hi Sandro, After updating the MOM project's build system, I have used jenkins to produce a set of RPMs that I would like to tag into the oVirt 3.4 release. Please see the jenkins job [1] for the relevant artifacts for EL6[2], F19[3], and F20[4]. Dan, should I submit a patch to vdsm to make it require mom >= 0.4.0? I want to be careful to not break people's environments this late in the 3.4 release cycle. What is the best way to minimize that damage?

[Engine-devel] bug-url requirement for stable branch backports
by Itamar Heim 31 Jan '14

31 Jan '14

I'm inclined to drop the "bug-url is required" for engine stable branch 3.4, until we GA 3.4, as a lot of the patches are for pre-GA features. 3.3 stable branch still has this requirement of course. thoughts anyone? Thanks, Itamar

Hi, while trying to add a new message I couldn't help notice some ugliness in the code regarding our error messages in UI - why do we have @DefaultStringValue in frontend/webadmin/modules/frontend/src/main/java/org/ovirt/engine/ui/frontend/AppErrors.java ? All strings are defined in individual properties anyway. - so we have individual properties files….3 of them REST - backend/manager/modules/dal/src/main/resources/bundles/AppErrors.properties UP - frontend/webadmin/modules/frontend/src/main/java/org/ovirt/engine/ui/frontend/AppErrors.java WA - frontend/webadmin/modules/userportal-gwtp/src/main/resources/org/ovirt/engine/ui/frontend/AppErrors.properties funnily enough it's not that there are more messages in WA than UP, no, it's just full of random omissions, typos and discrepancies which do not make any logical sense Can't we get rid of the defaults in the interface (useless) and have just one property containing all the messages and use the sam file in all 3 places. And only if there is intentionally a different message in e.g. UP than in WA we can have an override/additional property file there (just by briefly going through most of the differences there's not a single case) Thanks, michal

[Engine-devel] proposing Arik Hadas as a maintainer of engine core
by Michal Skrivanek 30 Jan '14

30 Jan '14

Dear engine-core maintainers, I'd like to propose Arik Hadas as a maintainer of oVirt engine backend Since he started with oVirt project in October 2012 he was working in various areas in engine core, demonstrated his abilities with more than 200 patches merged to engine master alone. Tons of migration related fixes, refactoring of legacy code, but also new complex features including complementary patches in UI, REST and VDSM code (e.g. Live Snapshots with RAM, locking improvements for VM&Template operations) Thanks in advance for your response. Thanks, michal

[Engine-devel] Predictable_vNIC_Order
by Meni Yakove 29 Jan '14

29 Jan '14

Hi, On oVirt 3.4 there is new feature: http://liver.englab.brq.redhat.com/redirect/?url=http://wiki.ovirt.org/Feat… Right now the feature make sure that the VNIC ordering for VM is the same after create VM from template/snapshot/import. For example: On original VM VNIC1 attached to network blue and VNIC2 attached to network red and on the VM we have two interfaces ETH0 and ETH1, after creating template from this VM and create VM from the template the order of the VNICs are the same for the new VM. On the VM from template the first VNIC is attached to blue network and the second VNIC is attached to red network but on the VM we have ETH2 and ETH3 I think that the feature should also include Sealing_Linux_VM: http://www.ovirt.org/Sealing_Linux_VM Whit this on the VM from template the interface naming will be the same as the original VM. (ETH0 and ETH1) Please share your opinion. Thanks Meni

[Engine-devel] ovirt-3.3.3 release postponed due to blockers
by Sandro Bonazzola 28 Jan '14

28 Jan '14

Hi, oVirt 3.3.3 release need to be postponed. A recent release of python-cpopen-1.3 is breaking dependency resolution on EL6 and F19 so vdsm can't be installed and node can't be composed. A recent change in vdsm-python-cpopen added the needed conflict against python-cpopen and removed Provides / Obsoletes on python-cpopen. But no new releases of python-cpopen is available fixing the correct Provides / Obsoletes pair. oVirt 3.3.2 / stable is affected too. Please fix Bug 1056470 - python-cpopen-1.3 is not providing obsoleted package. Bug 1056464 - python-cpopen-1.3 is not providing obsoleted package. ASAP. -- Sandro Bonazzola Better technology.

[Engine-devel] oVirt 3.4 test day - PPC support
by Barak Azulay 27 Jan '14

27 Jan '14

Hi, I tried to test various engine features related to PPC support, However since I don't have a real Power PC HW I tried using the fake PPC configuration introduced by http://gerrit.ovirt.org/#/c/18718 So I added the following configuration to /etc/vdsm/vdsm.conf on a x86_64 host: fake_kvm_support=true fake_kvm_architecture=ppc64 And indeed it looked successful as you can see below [root@bazulay1 ~]# vdsClient -s 0 getVdsCaps | grep -i cpu cpuCores = '4' cpuFlags = 'powernv,model_POWER7_v2.3' cpuModel = 'POWER 7 (fake)' cpuSockets = '1' cpuSpeed = '3401.000' cpuThreads = '8' However after creating the appropriate cluster: CPU Architecture = ppc64 CPU name = IBM POWER 7* (meaning I tried all IBM POWER 7... cpus) Adding the host always ended in non operational status with the error: "Host bazulay1 has architecture x86_64 and cannot join Cluster TESTDAY-CLUSTER which has architecture ppc64." Thanks Barak Azulay

[Engine-devel] Bug status
by Sandro Bonazzola 27 Jan '14

27 Jan '14

Hi maintainers, since there's no automation in place for moving bz from MODIFIED to ON_QA when we build a new release, please remember to take care of your bz and move them to ON_QA when you build your packages for beta / rc testing. I can just move to ON_QA bz moved to MODIFIED before yum repository composition but it's not a good way to go. Thanks, -- Sandro Bonazzola Better technology. Faster innovation.

by Tal Nisan 26 Jan '14

26 Jan '14

Hi core maintainers, I would like to propose Liron Aravot as an engine-core maintainer. Liron joined the oVirt project on June 2012, and has since contributed over 170 patches to master (not counting backports to various stable branches).

[Engine-devel] [Users] The machine type of one cluster
by Kewei Yu 26 Jan '14

26 Jan '14

Hi all: There is a "machine type" in cluster, It will decide which machine of Qemu will be used, When we add the first host into cluster, a default machine type is shown. We can correct the DB's value of the engine to set the machine type. I just want to know how dose cluster choice the default machine? It is decided by VDSM? Qemu? or It is only fixed value in engine's DB? Regard Kewei

[Engine-devel] "Guest Agent Data" under "Network Interfaces" empty
by Yedidyah Bar David 23 Jan '14

23 Jan '14

Hi all, I installed ovirt engine 3.4 beta with two VMs - one opensuse 13.1 with ovirt-guest-agent from [1] and another fedora 19 with oga from fedora. Both of them seem to work well - I can see installed applications, logged in user, memory usage. But in both of them, under "Network Interfaces", the "Guest Agent Data" tab on the right has just headers, with no data. 'vdsClient -s 0 getAllVmStats' on the host does show such data correctly for both VMs. Am I missing anything? Is it a bug, or I should do something to get there data from the agent (through vdsm)?

[Engine-devel] Inconsistent model->entity mapping in VmSnapshotListModel
by Martin Betak 23 Jan '14

23 Jan '14

Hi all, during some of my frontend patches I noticed that the properties - singleQxlPci - allowConsoleReconnect - runAndPause are not mapped from UnitVmModel to VM business entity in VmSnapshotListModel#onCloneVm method while being mapped in all other fronted VM-related *ListModels (UserPortalListModel, VmListModel, TemplateListModel) and also that the 'comment' property is not being mapped in UserPortalListModel#postVmNameUniqueCheck method. Since I know that copy & pasting the appropriate setter to 6 different places when adding new VM property can be tedious and very error prone I would like to ask the frontend maintainers if the above is desired behavior or just bug caused by omission. Best regards, Martin

[Engine-devel] Change in Engine user session timeout options
by Vojtech Szocs 22 Jan '14

22 Jan '14

Hi guys, this is just a small update, patch [1] was merged recently into master branch and also made its way into ovirt-engine-3.4 branch. This patch removes UserSessionTimeOutInvalidationInterval config option, so there's only UserSessionTimeOutInterval option now. You can use it to customize Engine user session expiration, which is 30 mins by default. [1] http://gerrit.ovirt.org/#/c/23113/ Regards, Vojtech

[Engine-devel] Application URI - saved anywhere?
by Ori Liel 22 Jan '14

22 Jan '14

Hi, RSDL lists the possible links that the user can activate in Rest-API. The URI of A link looks something like this: "/ovirt-engine/api/vms/{vm:id}/start" My question is about the prefix: "/ovirt-engine/api/". Until now RSDL was generated at run-time, under a running application server, and this prefix was received by querying for the base-uri of the current user's request. I'm in the process of enabling RSDL generation at build time, and thus won't have a request to get this URI from. I'm thinking to add this constant: "/ovirt-engine/api" somewhere in pom.xml files, and use it. Does that sound reasonable? (if not, why, and what do you think I should do instead?) Thanks, Ori.
