Hello, I have a Windows 10 guest, when I boot it, it goes in to Automatic Repair mode, and after some time reports it was unable to repair the PC. This is from an older snapshot ("snapshot1"), and if I try switching back to a more recent snapshot ("snapshot2"), libvirt reports that it can't find the snapshot:

libvirt.libvirtError: internal error: Child process (/usr/bin/qemu-img snapshot -a snapshot2 /var/lib/libvirt/images/win10.qcow2) unexpected exit status 1: qemu-img: Could not apply snapshot 'snapshot2': Failed to load snapshot: Invalid argument

Does anyone have any ideas why this might have happened, or any suggestions for how I can go about diagnosing/fixing this? This was a pretty simple Windows 10 VM, that I used for Microsoft Office. Everything was managed through virt-manager and most settings left at the original defaults. Thanks, Jack
