### problem **The migration of a Windows VM from VMware to KVM by using the "Import-Export Instances" functionality fails.** <img width="441" height="350" alt="Image" src="https://github.com/user-attachments/assets/065dffd8-18e8-44e7-93bc-d3c1a20810c6"; /> **In the process it seems that the conversion went well. This is how the files look on the disk.** <img width="873" height="177" alt="Image" src="https://github.com/user-attachments/assets/236d5536-1f1e-4830-ad5e-ccb6c1e6e1b1"; /> **The agent.log file states that a different version of virt-v2v should be used.** **Here is the log output of the agent.log:** 2025-09-02 10:23:50,393 WARN [resource.wrapper.LibvirtConvertInstanceCommandWrapper] (AgentRequest-Handler-2:[]) (logid:) Exception [Stream closed] occurred when attempting to run command [virt-v2v --root first -i ova /mnt/f16f10e2-5272-3087-b0e3-bf664ec5b296/12aca5b3-739a-44f4-b9af-50d67007007f/i-2-20-VM/ -o local -os /mnt/f16f10e2-5272-3087-b0e3-bf664ec5b296 -of qcow2 -on e34c9a09-d5ea-4191-890b-a04f6a8c9b48 -v ]. java.io.IOException: Stream closed at java.base/java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:168) at java.base/java.io.BufferedInputStream.read(BufferedInputStream.java:334) at java.base/sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:287) at java.base/sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:330) at java.base/sun.nio.cs.StreamDecoder.read(StreamDecoder.java:190) at java.base/java.io.InputStreamReader.read(InputStreamReader.java:177) at java.base/java.io.BufferedReader.fill(BufferedReader.java:162) at java.base/java.io.BufferedReader.readLine(BufferedReader.java:329) at java.base/java.io.BufferedReader.readLine(BufferedReader.java:396) at com.cloud.utils.script.OutputInterpreter.processError(OutputInterpreter.java:41) at com.cloud.utils.script.Script.execute(Script.java:305) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtConvertInstanceCommandWrapper.performInstanceConversion(LibvirtConvertInstanceCommandWrapper.java:410) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtConvertInstanceCommandWrapper.execute(LibvirtConvertInstanceCommandWrapper.java:134) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtConvertInstanceCommandWrapper.execute(LibvirtConvertInstanceCommandWrapper.java:61) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtRequestWrapper.execute(LibvirtRequestWrapper.java:78) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.executeRequest(LibvirtComputingResource.java:1958) at com.cloud.agent.Agent.processRequest(Agent.java:779) at com.cloud.agent.Agent$AgentRequestHandler.doTask(Agent.java:1194) at com.cloud.utils.nio.Task.call(Task.java:83) at com.cloud.utils.nio.Task.call(Task.java:29) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:840) 2025-09-02 10:23:50,393 ERROR [resource.wrapper.LibvirtConvertInstanceCommandWrapper] (AgentRequest-Handler-2:[]) (logid:) The virt-v2v conversion for the OVF 12aca5b3-739a-44f4-b9af-50d67007007f failed. Please check the agent logs for the virt-v2v output. Please try on a different kvm host which has a different virt-v2v version. ### versions virt-v2v 2.4.0 Ubuntu 24.04 LTS ACS 4.20.1.0 ### The steps to reproduce the bug 1. Configure the KVM hypervisor like described here: https://docs.cloudstack.apache.org/en/latest/adminguide/virtual_machines/importing_vmware_vms_into_kvm.html or https://www.shapeblue.com/cloudstack-vmware-to-kvm-migration-tool/ 2. Use the export import tool in CloudStack. 3. Choose a Windows VM to convert 4. Give it a name 5. Select the prepared hypervisor. 6. Wait until the error appears. Can take a while until the conversion happened, depending on the size of the disk.... ### What to do about it? _No response_ -- This is an automated message from the Apache Git Service.
