[PULL 01/23] qemu-img: omit errno value in error message

Posted by Michael Tokarev 1 year, 2 months ago

I'm getting io-qcow2-244 test failure on mips*
due to output mismatch:

  Take an internal snapshot:
 -qemu-img: Could not create snapshot 'test': -95 (Operation not supported)
 +qemu-img: Could not create snapshot 'test': -122 (Operation not supported)
  No errors were found on the image.

This is because errno values might be different across
different architectures.

This error message in qemu-img.c is the only one which
prints errno directly, all the rest print strerror(errno)
only.  Fix this error message and the expected output
of the 3 test cases too.

Ghrm. This shouldn't be sent here, this one should go via the block tree.
I'll re-send a v2.
