### problem Validate Qcow2 for a backing file during vm import Currently, CloudStack checks if a QCOW2 file has a backing file during the following operations and throws the following exception (Volume with backing file cannot be imported or unmanaged) https://prnt.sc/odMIHijU1pJ3 1. Register Template (Normal and Direct Download) https://cloudstack.apache.org/api/apidocs-4.20/apis/registerTemplate.html 2. Upload Volume https://cloudstack.apache.org/api/apidocs-4.20/apis/uploadVolume.html 3. Import Volume https://cloudstack.apache.org/api/apidocs-4.20/apis/importVolume.html The agent for the kvm host checks for backing for not and throws the exception ``` 2025-07-18 05:35:53,182 DEBUG [utils.script.Script] (AgentRequest-Handler-3:[]) (logid:) Executing command [qemu-img info -U /var/lib/libvirt/images/test-backing-file-sdb.qcow2 ]. 2025-07-18 05:35:53,190 DEBUG [utils.script.Script] (AgentRequest-Handler-3:[]) (logid:) Successfully executed process [28240] for command [qemu-img info -U /var/lib/libvirt/images/test-backing-file-sdb.qcow2 ]. ``` ### versions ACS 4.20.1 , ACS 4.19.x ### The steps to reproduce the bug 1. Create a backing file using qcow2 on a local storage or a shared storage qemu-img create -f qcow2 -b /dev/sdb -F raw test-backing-file-sdb.qcow2 5G 2. As a Admin user Navigate to Tools> Import-Export Instances > Kvm 3. Import Qcow2 image from Local Storage https://prnt.sc/NPU9hV6s6v_k 4. Import Qcow2 image from Shared Storage https://prnt.sc/uRmuv2j49KZW 5. The qcow2 file is imported successfully ### What to do about it? Expected behaviour Ideally, CloudStack should check if the volume has a backing file and throw the same exception during import vm https://cloudstack.apache.org/api/apidocs-4.20/apis/importVm.html -- This is an automated message from the Apache Git Service.
