[Engine-devel] [action needed] failing jenkins job "ovirt db report engine"
by Eyal Edri 11 Sep '13

11 Sep '13

fyi, the following job [1] is failing due to missing files on the slave (it used local files/software). the original slave is now not available. does this jobs is still needed? is so, the owner of the job should write a puppet class to install needed files for it so it won't be locally only on the jenkins slaves (which should be stateless). job will be disabled until fixed.

[Engine-devel] Question about Disk Hotplug
by Gustavo Frederico Temple Pedrosa 11 Sep '13

--_000_EF26FC1776F7FF46BFC072393EFD13A29A4FC8SERV070corpeldora_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi everyone, We proposed some changes in how to query if an operating system supports ho= tplug, then Itamar suggested that disk hotplugging and NIC hotplugging coul= d be separated from each other. While it is pretty clear how to put info ab= out NIC hotplugging in the osinfo, here are a few issues when trying to int= roduce the same concept for disk hotplugging. Some disk interfaces do not support hotplugging at all (like IDE), some of = them support it in the x86_64, but not in the ppc64 architecture (like the = VirtIO blk) and others support it in both architectures (like VirtIO SCSI).= There is also a ppc64 specific controller called SPAPR VSCSI, which suppor= ts it too. So, how do you propose a syntax to cover all these cases? I thought about something along the lines of: os.{id}.devices.disk.hotpluggableInterfaces =3D VirtIO_SCSI, VirtIO Thanks, Leonardo Bianconi/Vitor de Lima/Gustavo Pedrosa --_000_EF26FC1776F7FF46BFC072393EFD13A29A4FC8SERV070corpeldora_ 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"PT-BR" link=3D"blue" vlink=3D"purple"> <div class=3D"WordSection1"> <p class=3D"MsoNormal"><span lang=3D"EN-US">Hi everyone,<o:p></o:p></span><= /p> <p class=3D"MsoNormal"><span lang=3D"EN-US"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span lang=3D"EN-US">We proposed some changes in how= to query if an operating system supports hotplug, then Itamar suggested th= at disk hotplugging and NIC hotplugging could be separated from each other.= While it is pretty clear how to put info about NIC hotplugging in the osinfo, here are a few issues when tryin= g to introduce the same concept for disk hotplugging.<o:p></o:p></span></p> <p class=3D"MsoNormal"><span lang=3D"EN-US"><o:p> </o:p></span></p> <p class=3D"MsoNormal"><span lang=3D"EN-US">Some disk interfaces do not sup= port hotplugging at all (like IDE), some of them support it in the x86_64, = but not in the ppc64 architecture (like the VirtIO blk) and others support = it in both architectures (like VirtIO SCSI).

The main idea is to disable NIC hotplugging in PPC64 VMs, but = listing explicitly every ppc64 os in "HotPlugUnsupportedOsList" config valu= e does not look like a clean way to do so.

[Engine-devel] Storing command parameters
by Sahina Bose 08 Sep '13

08 Sep '13

Hi all, As part of the gluster volume asynchronous tasks, we ran into a requirement wherein when we start a command, we need to remember the parameters that the command was started with. Is there any infrastructure available to do this, or should we build something? thanks sahina

I just wanted to say what an amazing feature page this is: http://www.ovirt.org/Features/Multiple_Gateways I especially like the "Why do we need this feature" part. It is all so well laid out and presented. Nice work Assaf! Tim Hildred, RHCE, RHCVA Content Author II - Engineering Content Services, Red Hat, Inc.

[Engine-devel] Question about API REST

--_000_EF26FC1776F7FF46BFC072393EFD13A29A40C6SERV070corpeldora_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hello everyone, I'm adding the architecture meta-field of VMs, Templates and Clusters in RE= ST API (see change #16700 in gerrit). It's a read-only field (like a "final= " in Java), that the administrator cannot change it, but there are some sit= uations where there might be a value for it, such as when an entity is rece= ived from the API, slightly modified and then its update method is called. = So I would like to ask these questions about how to implement it: 1) Should this attribute be mapped both ways (from the REST API to the engi= ne and vice-versa)? 2) How should this field be declared in the rdsl_metadata? Do I have to exp= licitly put it in the optional arguments or should I omit it? 3) How can I make this field strictly immutable (like the ID field is), giv= en that the architecture is a field of the CPU entity, and the methods used= to check for invalid updates can only operate on fields that belong direct= ly to the main entity?
