[PATCH 5/5] qemuProcessHandleIOError: Log IO errors in the VM log file
Add a log entry to the VM log file for every time we receive an IO error
event from qemu. The log entry is as follows:
2025-01-24 16:03:28.928+0000: IO error device='virtio-disk0'
node-name='libvirt-1-storage' reason='other: Input/output error'
