When running the command `qemu-img snapshot -l SNAPSHOT` the output of VM_CLOCK (measures the offset between host and VM clock) cannot to accommodate values in the order of thousands (4-digit). This line [1] hints on the problem. Additionally, the column width for the VM_CLOCK field was reduced from 15 to 13 spaces in commitb39847a5in line [2], resulting in a shortage of space. [1]: https://gitlab.com/qemu-project/qemu/-/blob/master/block/qapi.c?ref_type=heads#L753 [2]: https://gitlab.com/qemu-project/qemu/-/blob/master/block/qapi.c?ref_type=heads#L763 This patch restores the column width to 15 spaces and makes adjustments to the affected iotests accordingly. Furthermore, addresses a potential source of confusion by removing whitespace in column headers. Example, VM CLOCK is modified to VM_CLOCK. Additionally a '--' symbol is introduced when ICOUNT returns no output for clarity.
