CST VerdictBased on our analysis of available product data, here is our conclusion:
Forensic investigators and incident responders who need to parse QCOW disk images without touching the host filesystem will find libqcow indispensable; it's the only read-only parser that handles multiple QCOW versions and compression formats in a single library. The tool has been in active development across cloud forensics workflows where QEMU-based infrastructure dominates, and its GitHub presence reflects genuine adoption in labs processing virtual machine evidence. Skip this if you need write capability or GUI-based triage; libqcow is strictly a programmatic library for analysts comfortable integrating it into Python or C workflows.
Forensic investigators and incident responders who need to parse VMware virtual machines during post-breach analysis should reach for libvmdk; it's the only open-source tool that lets you read and extract data from VMDK files without spinning up the hypervisor. The 183 GitHub stars and active maintenance signal it's stable enough for court-admissible evidence chains. Skip this if your team works primarily with Hyper-V or cloud-native snapshots, or if you need a GUI; libvmdk is command-line only and VMware-specific.
