Hi, I have RHEL 6.2 KVM host with libvirt (0.9.4-23.el6). This is added to 4.2 Cloudstack Management server.
With this KVM host, system VM's are failed to start with error as: 2013-07-11 14:22:45,946 WARN [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-1:null) LibvirtException org.libvirt.LibvirtException: internal error unknown timer name 'kvmclock' at org.libvirt.ErrorHandler.processError(Unknown Source) at org.libvirt.Connect.processError(Unknown Source) at org.libvirt.Connect.domainCreateXML(Unknown Source) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.startVM(LibvirtComputingResource.java:1126) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.execute(LibvirtComputingResource.java:3293) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.executeRequest(LibvirtComputingResource.java:1222) at com.cloud.agent.Agent.processRequest(Agent.java:525) at com.cloud.agent.Agent$AgentRequestHandler.doTask(Agent.java:852) at com.cloud.utils.nio.Task.run(Task.java:83) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679) ASF Dev list there is a suggestion to upgrade Libvirt version to 1.0.2 to resolve this issue. I am getting into lot of dependency failures to upgrade the libvirt version. Has any one tried this workaround? Will it cause for any issues to existing environments(4.x /3.0.x with KVM 6.2) after upgrade to 4.2 ? Thanks, Sailaja.M
