CephFS
by Markus Stockhausen 31 May '18

31 May '18

Hi there, coming from Gluster (standalone, mounted on nodes via fuse) and NFS storage domains we want to give Ceph a try. If I understand it right it should be possible to mount it in 3 ways. 1. via Cinder 2. via NFS (ganesha) 3. via CephFS (Posix) We do not need highest performance and want to keep things simple on the OVirt side (like NFS). From management/integration perspective CephFS seems to be the way to go. Any thoughts I missed that could favour the other setups? Best regards. Markus

Re: Simple API call to start VM

Many thanks to: gsswzt, Luca, Andrej, Fred, Karli, Ondra and Bohdan for their replies. A number of people mentioned the need to specify a CA cert, but curl was able to find my organizations CA locally - so that was not an issue. Correcting my url to include ovirt-engine in the path and my username to admin@internal as suggested by Andrej as per below: curl --user "admin@internal:SECRETPASSWORD" --request POST --header "Content-Type: application/xml" --header "Accept: application/xml" --data '</action>' https://ovirt-engine.localnet:443/ovirt-engine/api/vms/69c47a91-bbv1-4eda-b… Got me a new error message: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>For correct usage, see: https://ovirt-engine.localnet/ovirt-engine/apidoc#services/vm/methods/start </detail> <reason>Request syntactically incorrect.</reason> </fault> I followed the URL, but it just seemed to repeat the information already available at http://ovirt.github.io/ovirt-engine-api-model/4.2/#services/vm/methods/start Here is the relevant section of engine.log on ovirt-engine.localnet: 2018-05-31 10:48:15,550+10 INFO [org.ovirt.engine.core.sso.utils.AuthenticationUtils] (default task-25) [] User admin@internal successfully logged in with scopes: ovirt-app-api ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access 2018-05-31 10:48:15,569+10 INFO [org.ovirt.engine.core.bll.aaa.CreateUserSessionCommand] (default task-29) [8ffa0f3] Running command: CreateUserSessionCommand internal: false. 2018-05-31 10:48:15,581+10 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-29) [8ffa0f3] EVENT_ID: USER_VDC_LOGIN(30), User admin@internal-authz connecting from '192.168.1.0' using session 'JNweIEHoHhw9U+wMt7Z03Ovb5Pc1zR3WyvTcSfRTpdHjd55CHbcspfDcJgToMVshtlgXamzvUSW2rzHB9ApJHA==' logged in. 2018-05-31 10:48:15,587+10 ERROR [org.ovirt.engine.api.restapi.resource.validation.IOExceptionMapper] (default task-29) [] IO exception while processing "POST" request for path "/vms/69c47a91-bbv1-4eda-b71d-7bddf82ee8ab/start" 2018-05-31 10:48:15,587+10 ERROR [org.ovirt.engine.api.restapi.resource.validation.IOExceptionMapper] (default task-29) [] Exception: java.io.IOException: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,2] Message: The markup in the document preceding the root element must be well-formed. at org.ovirt.engine.api.restapi.xml.JAXBProvider.readFrom(JAXBProvider.java:200) [restapi-jaxrs.jar:] at org.ovirt.engine.api.restapi.xml.JAXBProvider.readFrom(JAXBProvider.java:162) [restapi-jaxrs.jar:] at org.jboss.resteasy.core.interception.AbstractReaderInterceptorContext.readFrom(AbstractReaderInterceptorContext.java:66) [resteasy-jaxrs-3.0.24.Final.jar:3.0.24.Final] at org.jboss.resteasy.core.interception.ServerReaderInterceptorContext.readFrom(ServerReaderInterceptorContext.java:61) [resteasy-jaxrs-3.0.24.Final.jar:3.0.24.Final] at org.jboss.resteasy.core.interception.AbstractReaderInterceptorContext.proceed(AbstractReaderInterceptorContext.java:56) [resteasy-jaxrs-3.0.24.Final.jar:3.0.24.Final] at org.jboss.resteasy.security.doseta.DigitalVerificationInterceptor.aroundReadFrom(DigitalVerificationInterceptor.java:36) [resteasy-crypto-3.0.24.Final.jar:3.0.24.Final] <MANY MANY LINES OF ERRORS SNIPPED> at java.lang.Thread.run(Thread.java:748) [rt.jar:1.8.0_171] Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,2] Message: The markup in the document preceding the root element must be well-formed. at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:604) [rt.jar:1.8.0_171] at com.sun.xml.bind.v2.runtime.unmarshaller.StAXStreamConnector.bridge(StAXStreamConnector.java:164) at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal0(UnmarshallerImpl.java:415) at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal(UnmarshallerImpl.java:386) at org.ovirt.engine.api.restapi.xml.JAXBProvider.readFrom(JAXBProvider.java:187) [restapi-jaxrs.jar:] ... 104 more 2018-05-31 10:48:15,593+10 INFO [org.ovirt.engine.core.bll.aaa.LogoutSessionCommand] (default task-29) [4531c52a] Running command: LogoutSessionCommand internal: false. 2018-05-31 10:48:15,598+10 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-29) [4531c52a] EVENT_ID: USER_VDC_LOGOUT(31), User admin@internal-authz connected from '192.168.1.0' using session 'JNweIEHoHhw9U+wMt7Z03Ovb5Pc1zR3WyvTcSfRTpdHjd55CHbcspfDcJgToMVshtlgXamzvUSW2rzHB9ApJHA==' logged out. 2018-05-31 10:48:27,542+10 INFO [org.ovirt.engine.core.sso.servlets.OAuthRevokeServlet] (default task-32) [] User admin@internal successfully logged out 2018-05-31 10:48:27,550+10 INFO [org.ovirt.engine.core.bll.aaa.TerminateSessionsForTokenCommand] (default task-35) [76676851] Running command: TerminateSessionsForTokenCommand internal: true.

Attaching previously owned storage domain to 4.2 Cluster
by John Nguyen 31 May '18

31 May '18

Hi Guys, I'm working through a disaster recovery of a failed cluster. And I found the documentation for attaching the old storage domain as an import domain to a new Cluster. Both clusters are 4.2. https://ovirt.org/develop/release-management/features/storage/importstorage… The documentation is referencing 3.5 and I would like to know if its still applies to the 4.2 release. When I try to do the import I see warnings below: I know that its really hard to say this operation may not be destructive. But is the general work flow outlined in the 3.5 documentation still valid? Thanks, John

Simple API call to start VM

Hi oVirt users, I have (what I hope) is a simple problem. I want to make an https request to start a VM via the oVirt REST API.

Use an oVirt-VM as a VDSM server
by James Michels 30 May '18

30 May '18

Greetings. In terms of teaching our students how to create and configure an oVirt infrastructure, we're planning to provide each of them a VM that will act as a Manager server, which has no issues so far. The problem is that we don't have enough physical machines to use as virtualization servers (VDSM), therefore we have been trying to use a CentOS7 based oVirt guest to run as a VDSM server. However, when trying to add it as a host, a (logical) error message shows up saying that the VM doesn't allow virtualization. The question is simple: Is there a way to enable virtualization on an oVirt VM, so we can deploy them as VDSM servers? This is oVirt 4.2.2 FWIW. Thanks James
