Hey Marcus, So, I went back to the branch of mine that has your code and mine and was able to create a new CloudStack install from scratch with it (once again, after manually deleting what was in /var/lib/libvirt/images to the get system VMs to start).
Anyways, my system VMs are running now and I tried to kick off a VM using the CentOS 6.3 image you provided me a while back. The virtual router has a Status of Running; however, my VM fails to start (with the generic message of Insufficient Capacity). I've not seen this exception before (related to the VR). Do you have any insight into this?: com.cloud.exception.ResourceUnavailableException: Resource [Pod:1] is unreachable: Unable to apply userdata and password entry on router at com.cloud.network.router.VirtualNetworkApplianceManagerImpl.applyRules(VirtualNetworkApplianceManagerImpl.java:3793) at com.cloud.network.router.VirtualNetworkApplianceManagerImpl.applyUserData(VirtualNetworkApplianceManagerImpl.java:3017) at com.cloud.network.element.VirtualRouterElement.addPasswordAndUserdata(VirtualRouterElement.java:933) at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.prepareElement(NetworkOrchestrator.java:1172) at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.prepareNic(NetworkOrchestrator.java:1288) at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.prepare(NetworkOrchestrator.java:1224) at com.cloud.vm.VirtualMachineManagerImpl.advanceStart(VirtualMachineManagerImpl.java:826) at com.cloud.vm.VirtualMachineManagerImpl.start(VirtualMachineManagerImpl.java:508) at org.apache.cloudstack.engine.cloud.entity.api.VMEntityManagerImpl.deployVirtualMachine(VMEntityManagerImpl.java:227) at org.apache.cloudstack.engine.cloud.entity.api.VirtualMachineEntityImpl.deploy(VirtualMachineEntityImpl.java:209) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:3338) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:2919) at com.cloud.vm.UserVmManagerImpl.startVirtualMachine(UserVmManagerImpl.java:2905) at com.cloud.utils.component.ComponentInstantiationPostProcessor$InterceptorDispatcher.intercept(ComponentInstantiationPostProcessor.java:125) at org.apache.cloudstack.api.command.user.vm.DeployVMCmd.execute(DeployVMCmd.java:421) at com.cloud.api.ApiDispatcher.dispatch(ApiDispatcher.java:161) at com.cloud.api.ApiAsyncJobDispatcher.runJobInContext(ApiAsyncJobDispatcher.java:109) at com.cloud.api.ApiAsyncJobDispatcher$1.run(ApiAsyncJobDispatcher.java:66) 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 com.cloud.api.ApiAsyncJobDispatcher.runJob(ApiAsyncJobDispatcher.java:63) at org.apache.cloudstack.framework.jobs.impl.AsyncJobManagerImpl$1.runInContext(AsyncJobManagerImpl.java:532) at org.apache.cloudstack.managed.context.ManagedContextRunnable$1.run(ManagedContextRunnable.java:49) at org.apache.cloudstack.managed.context.impl.DefaultManagedContext$1.call(DefaultManagedContext.java:56) at org.apache.cloudstack.managed.context.impl.DefaultManagedContext.callWithContext(DefaultManagedContext.java:103) at org.apache.cloudstack.managed.context.impl.DefaultManagedContext.runWithContext(DefaultManagedContext.java:53) at org.apache.cloudstack.managed.context.ManagedContextRunnable.run(ManagedContextRunnable.java:46) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Thanks!
