[Engine-devel] Problem with detachment of host interface using ovirt-sdk

--_000_4488206DC085244C886DBC9E7038B68918D382CEMTRDAG01mtlcom_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I'm using ovirt-sdk to attach and detach a network to a host's Interface. Once the network is attached to the interface I try to detach the network f= rom the interface using the following steps: 1.Detach the network from the cluster through the GUI. 2.Remove the network from the datacenter through the GUI. 3.Detach the network from the host's interface using the SDK: nic =3D api.hosts.get(name=3Dhost).nics.get(name=3Dif_name) net =3D params.Network(name=3Dnet_name) act =3D params.Action(network=3Dnet) nic.detach(act) api.hosts.get(name=3Dhost).commitnetconfig() Then I get the error: http://pastebin.com/3Md07huE The same flow using the GUI works fine. Network removal from the Datacenter is a trigger for me to run the detachme= nt operation therefore I use this flow. I use the following components: rhevm-3.0.2_0001-2 ovirt-sdk (Using the latest from git repository) Please advise how to proceed. Thanks, Itzik --_000_4488206DC085244C886DBC9E7038B68918D382CEMTRDAG01mtlcom_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"= > <meta name=3D"Generator" content=3D"Microsoft Word 14 (filtered medium)"> <style></style> </head> <body lang=3D"EN-US" link=3D"blue" vlink=3D"purple"> <div class=3D"WordSection1"> Hi,<o:p></o:p> <o:p> </o:p> I'm using ovirt-sdk to attach and detach a network to a host's Inter= face.<o:p></o:p> Once the network is attached to the interface I try to detach the ne= twork from the interface using the following steps:<o:p><= /o:p> <o:p> </o:p> 1.Detach the network from the cluster through the GUI.<o:p></o:p></p= > 2.Remove the network from the datacenter through the GUI.<o:p></o:p>= 3.Detach the network from the host's interface using the SDK:<o:p></= o:p> <o:p> </o:p> nic = =3D api.hosts.get(name=3Dhost).nics.get(name=3Dif_name)<o:p></o:p> net = =3D params.Network(name=3Dnet_name)<o:p></o:p> act = =3D params.Action(network=3Dnet)<o:p></o:p> nic.d= etach(act)= <o:p></o:p> api.h= osts.get(name=3Dhost).commitnetconfig()<o:p></o:p> <o:p> </o:p> Then I get the error:<o:p></o:p> <a href=3D"http://pastebin.com/3Md07huE">http://pastebin.com/3Md07hu= E</a><o:p></o:p> <o:p> </o:p> The same flow using the GUI works fine.<o:p></o:p> <o:p> </o:p> Network removal from the Datacenter is a trigger for me to run the d= etachment operation therefore I use this flow.<o:p></o:p> <o:p> </o:p> I use the following components:<o:p></o:p> <o:p> </o:p> rhevm-3.0.2_0001-2<o:p></o:p> ovirt-sdk (Using the latest from git repository)<o:p></o:p> <o:p> </o:p> Please advise how to proceed.<o:p></o:p> <o:p> </o:p> Thanks,<o:p></o:p> Itzik<o:p></o:p> </div> </body> </html> --_000_4488206DC085244C886DBC9E7038B68918D382CEMTRDAG01mtlcom_--

[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] Manual DB change required - remove grant_mode column from DB
by Moti Asayag 29 Mar '12

29 Mar '12

Hi, The commit which added the grant_mode column to the permissions table was reverted (604ae480ab677b06e53abd0edfaf0ec04f017fb8). If you upgraded the DB since the 25/3, please run manually the next command in order to drop that column and run refresh procedure afterwards/run upgrade script: echo 'alter table permissions drop column grant_mode' | psql engine postgres (supply database name if differ from engine). Thanks, Moti

[Engine-devel] Getting rid of PowerMock?
by Yair Zaslavsky 29 Mar '12

29 Mar '12

Hi all, As (almost) all of us can see, Running BLL tests both takes considerable time, and also we have to take class loading dependencies between classes with static methods when we use mockStatic - IMHO, this is kinda frustrating. Maybe we should start get rid of PowerMock. Here is what I'm thinking of - Currently, as we use no IoC for DAOs , for tested class we do not use DbFacade.getInstance().getXXXDao() instead we define: protected XXXDao getXXXDao() { return DBFacade.getInstance().getXXXDao(); } And then in our tests we use Mockito to define how getXXDao acts in the test. The following can be achieved also for config values , the following way - protected <T> T getConfig(ConfigValues key) { return Config.<T> GetValue(key); } And then in code (for example, in a query test) - doReturn(5).when(query).<Integer> getConfig(any(ConfigValues.SomeIntegerConstant)); This effort can be done in small steps - a. Define getConfig method in base classes (i.e AuditLoggalbeBase). b. Rewrite parts (i.e Commands, and their tests) step by step (small commits) Thoughts and ideas are more than welcome, Yair

[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.
