[ovirt-devel] Really slow VDSM on F21
Hello, has anyone else noticed VDSM's problems on Fedora 21? The problem is that when I start vdsmd via systemd, it takes about a minute to start the listener (returning Connection to 0.0.0.0:54321 refused) and next few minutes it returns 'Recovering from crash or Initializing'. After that, `getVdsCaps` takes cca 20 secs to finish. I tried to change niceness in vdsmd.service but it's still the same. When I start vdsm directly (/usr/share/vdsm/vdsm as vdsm user) it starts within a second as it should. Have you an idea why this happens?

While analyzing/reverse-engineering oVirt Java SDK, some thoughts came to my mind, and I wanted to share them with you. [*] TODO(vszocs) upload new patchset with all recent changes First, the way XJC (JAXB binding compiler that generates Java beans out of REST XSD schema) is invoked looks a bit weird to me, as Java SDK's XsdCodegen does this: Runtime.getRuntime().exec(command) Why not simply use existing Maven plugins to invoke XJC? - either: https://github.com/highsource/maven-jaxb2-plugin https://github.com/highsource/maven-jaxb2-plugin [MP] sdk was using jaxb to begin with, it was replaced with XJC just recently, btw Juan, what was the motivation behind this? This didn't change, the use of xjc is there since commit 95a25a4, Nov 12 2012. Note that using Maven for this isn't as simple as it may look. The development model of the SDK is that the maven build does *not* generate any code, it just builds what has been manually generated previously. To clarify, my question was meant for ovirt-engine-sdk-java-codegen project and its org.ovirt.engine.sdk.codegen.Main class that produces Java classes out of XSD as part of XsdCodegen.generate() method. But if XsdCodegen invokes XJC programatically, what is the purpose of: org.jvnet.jaxb2.maven2:maven-jaxb22-plugin:generate in ovirt-engine-sdk-java-codegen project's pom.xml? Is it related to what XsdCodegen is doing? The code generator invokes xjc directly in order to generate from the XML schema the code that will eventually be part of the generated SDK. In order to do its work it needs to parse the RSDL metadata, and for that it uses JAXB and classes generated from the XML schema. Those classes are generated as part of the build process of the code generator. So the XML schema is converted into Java classes twice: once for the internal use of the generator (during build time of the generator), and another time for the generated SDK (during run time of the generator). This is convenient in order to avoid dependencies between the generator and the SDK. Thanks for clarification. IMHO calling XJC just to generate JAXB code that parses RSDL data is an overkill. In oVirtJS GWT wrapper project, I'm parsing RSDL as XML file directly. The xjc compiler isn't called directly to generate the code to parse RSDL, it is called to generate the code of the SDK. Yes, that's what XsdCodegen is doing. The code that the generator uses internally is generated using the Maven plugin (which in turn calls xjc). Yes, that's what maven-jaxb22-plugin is doing in ovirt-engine-sdk-java-codegen/pom.xml file. We could argue about the convenience of using JAXB or manually parsing the RSDL, but it won't take us anywhere. If you find it convenient parsing it directly just do it. Conceptually, RSDL definition shouldn't even be inside api.xsd: xs:element name=rsdl type=RSDL/ Above ^^ is unrelated to REST entity schema, it describes RSDL schema. It's inside api.xsd just to parse RSDL via JAXB. Entity schema and RSDL schema are two separate things. I suggest to split above into separate file, i.e. rsdl.xsd and reference shared types (like Version) from api.xsd. This would be the proper separation these two schemas. The RSDL is just one resource offered by the RESTAPI, like a VM or a host. It supports multiple formats (XML, JSON, etc) and it is consumed by clients. So its entities, like any other entity, must be described in the XML schema. We only have one XML schema, and we can split it as it would
