Okay, I need to classify this bug report based on the categories provided. Let's read through the problem again carefully. The user is using QEMU/KVM with qcow2 images. They created an image with a specific size (10G), but it keeps growing beyond that limit when data is added after deleting some files in the guest OS. The real issue here is that the physical size of the image exceeds the virtual limit set during creation, and this happens even though they've deleted data which should free up space but doesn't cause the image to shrink. The possible categories are: mistranslation, assembly, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. I'm thinking about what part of QEMU is causing this. The qcow2 image is a disk image format that allows for sparse images and supports features like snapshots. If the image grows beyond the specified virtual size, it suggests an issue with how the file's growth is being managed. Looking at the categories, "files" seems relevant because it relates to how the filesystem handles files and their sizes. Another category could be "hypervisor," but the problem isn't directly related to KVM or VNC in this context; it's more about disk management. The issue arises from file operations within QEMU when handling storage, so "files" might be appropriate. I don't think it's mistranslation because that would involve incorrect mapping between architectures, which doesn't apply here. Assembly lowering is also unrelated. Other categories like network or socket aren't involved in this scenario. So, the most fitting category seems to be "files," as it pertains to file handling and growth beyond expected limits within the disk image management. The issue relates to how QEMU handles the growth of qcow2 images, particularly when data is added after deletion. This affects the file's physical size exceeding its virtual limit. The problem lies in the filesystem operations and storage management within QEMU, making "files" the appropriate category. **Answer:** files
