bf89e87427fb99b994eb0dfb710bb4b45785f733 vhdx: Fix "log that needs to be replayed" error message
The arguments of error_setg_errno() should yield a short error string
without newlines.
Here, we try to append additional help to the error message by
embedding newlines in the error string. That's nice, but it's doesn't
play nicely with the errno part. tests/qemu-iotests/070.out shows the
resulting mess:
can't open device TEST_DIR/iotest-dirtylog-10G-4M.vhdx: VHDX image file 'TEST_DIR/iotest-dirtylog-10G-4M.vhdx' opened read-only, but contains a log that needs to be replayed. To replay the log, execute:
qemu-img check -r all 'TEST_DIR/iotest-dirtylog-10G-4M.vhdx': Operation not permitted
Switch to error_setg() and error_append_hint(). Result:
can't open device TEST_DIR/iotest-dirtylog-10G-4M.vhdx: VHDX image file 'TEST_DIR/iotest-dirtylog-10G-4M.vhdx' opened read-only, but contains a log that needs to be replayed
To replay the log, run:
qemu-img check -r all 'TEST_DIR/iotest-dirtylog-10G-4M.vhdx'
