Once Windows 8.1 boots:

virsh domblklist win81 # Find disk target (e.g., vda) virsh snapshot-create --disk-only --atomic win81 cp /var/lib/libvirt/images/windows81.qcow2 /backup/windows81_backup.qcow2 virsh blockcommit win81 vda --active --verbose --pivot

Absolutely. While Windows 8.1 is an older OS (end of support as of January 2023), it remains lightweight and efficient for legacy software or low-resource environments. Using a QCOW2 image on KVM gives you snapshot capabilities, thin provisioning, and near-native performance.
