Hi, Rakesh, thanks!
After further digging the logs so far I can find: Destroying vm VM[User|i-291-77209-VM] as it failed to create on Host with Id:null VM state transitted from :Stopped to Error with event: OperationFailedToErrorvm's original host id: null new host id: null host id before state transition: null Additionally, via the log ID I've found an error which contains some base64 encoding but does not decode well i.e. base64 exits with an error and outputs something lengthy (2972 chars) looking like a Java stack trace but with random binary characters. Error: [o.a.c.f.j.i.AsyncJobManagerImpl] (Work-Job-Executor-92:ctx-0c7bb167 job-1027206/job-1027210 ctx-74dde55e) (logid:2477aa66) Complete async job-1027210, jobStatus: FAILED, resultCode: 0, result: rO0ABXNyAC9jb20u..... What is readable in this "base64" output is (special characters replaced with hyphen or new line): com.cloud.utils.exception.CloudRuntimeExceptionVMOI csErrorCodexr-java.lang.RuntimeException-detailMessaget Ljava/lang/String;[ xr-java.lang.Throwable-Lcauset-Ljava/lang/Throwable;L stackTracet-[Ljava/lang/StackTraceElement; L-suppressedExceptionst-Ljava/util/Lis kind regards Peter ________________________________________ Von: Rakesh Venkatesh [www.rakeshv....@gmail.com] Gesendet: Montag, 29.

The usual errors are insufficient server capacity exception like not enough cpu, memory, ip address or mismatch between template tag and host tag or some other mismatch in the tags. These are the common errors I have seen. Search for "startVirtualMachine" api and trace its jobid which is usually like "context-<some number>" and look at the logs On Mon, Apr 29, 2019 at 12:58 PM <peter.murysh...@zv.fraunhofer.de> wrote: > Hi, all, > > sometimes the system can't start a VM instance (a 530 error). > In the logs there is the following trace - how to troubleshoot it and > understand which circumstances lead to it? > > > com.cloud.utils.exception.CloudRuntimeException: Unable to start VM > instance > at > com.cloud.vm.VirtualMachineManagerImpl.orchestrateStart(VirtualMachineManagerImpl.java:4889) > at sun.reflect.GeneratedMethodAccessor433.invoke(Unknown Source) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > com.cloud.vm.VmWorkJobHandlerProxy.handleVmWorkJob(VmWorkJobHandlerProxy.java:107) > at > com.cloud.vm.VirtualMachineManagerImpl.handleVmWorkJob(VirtualMachineManagerImpl.java:5047) > at > com.cloud.vm.VmWorkJobDispatcher.runJob(VmWorkJobDispatcher.java:102) > at > org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$5.runInContext(AsyncJobManagerImpl.java:615) > at > org.apache.cloudstack.managed.context.ManagedContextRunnable$1.run(ManagedContextRunnable.java:49) > at > org.apache.cloudstack.managed.context.impl.DefaultManagedContext$1.call(DefaultManagedContext.java:56) > at > org.apache.cloudstack.managed.context.impl.DefaultManagedContext.callWithContext(DefaultManagedContext.java:103) > at > org.apache.cloudstack.managed.context.impl.DefaultManagedContext.runWithContext(DefaultManagedContext.java:53) > at > org.apache.cloudstack.managed.context.ManagedContextRunnable.run(ManagedContextRunnable.java:46) > at > org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$5.run(AsyncJobManagerImpl.java:563) > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) > at java.lang.Thread.run(Thread.java:748) > > kind regards > Peter > > -- Thanks and regards Rakesh venkatesh
