DennisKonrad commented on issue #3179: Redundant VRouter guest network on wrong interface URL: https://github.com/apache/cloudstack/issues/3179#issuecomment-558698138 @weizhouapache I tested multiple things that work fine (for redundant VPC offering): - [x] NAT is working (one NAT ip) - [x] Settings seem to go to both routers - [x] Redundancy heals when one router dies - [x] Failover of traffic works when one master dies - [x] Adding multiple Guest Networks works For things that do not work I have found: At the moment it's only possible to deploy one VM in a GuestNet (when using redundant VPC with OvS). For the second VM an error occurs. If one deletes that one working VM it's possible to deploy again. But max 1 VM. Even if I try to deploy in another GuestNet (in the same VPC). Management log only shows: <details><summary>click to unfold</summary> <p> ```INFO [o.a.c.a.c.u.v.DeployVMCmd] (API-Job-Executor-34:ctx-6242853f job-107 ctx-b55ef55c) (logid:852387c4) Unable to create a deployment for VM[User|i-4-18-VM] com.cloud.exception.InsufficientServerCapacityException: Unable to create a deployment for VM[User|i-4-18-VM]Scope=interface com.cloud.dc.DataCenter; id=1 at org.apache.cloudstack.engine.cloud.entity.api.VMEntityManagerImpl.reserveVirtualMachine(VMEntityManagerImpl.java:215) at org.apache.cloudstack.engine.cloud.entity.api.VirtualMachineEntityImpl.reserve(VirtualMachineEntityImpl.java:200) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:4676) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:4231) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:4221) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:338) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:197) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:163) at org.apache.cloudstack.network.contrail.management.EventUtils$EventInterceptor.invoke(EventUtils.java:107) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:174) at com.cloud.event.ActionEventInterceptor.invoke(ActionEventInterceptor.java:51) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:174) at org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke(ExposeInvocationInterceptor.java:92) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:185) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:212) at com.sun.proxy.$Proxy204.startVirtualMachine(Unknown Source) at org.apache.cloudstack.api.command.user.vm.DeployVMCmd.execute(DeployVMCmd.java:588) at com.cloud.api.ApiDispatcher.dispatch(ApiDispatcher.java:156) at com.cloud.api.ApiAsyncJobDispatcher.runJob(ApiAsyncJobDispatcher.java:108) at org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$5.runInContext(AsyncJobManagerImpl.java:583) 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$5.run(AsyncJobManagerImpl.java:531) at java.util.concurrent.Executors$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) ``` </p> </details> <br> Also I noticed another error in the management log that could be related: <details><summary>click to unfold</summary> <p> ```ERROR [o.a.c.e.o.NetworkOrchestrator] (API-Job-Executor-32:ctx-d8346e02 job-92 ctx-5a62bb49) (logid:c681419d) Failed to remove dhcp-dns entry due to: com.cloud.exception.ResourceUnavailableException: Resource [DataCenter:1] is unreachable: Can't find at least one router!
