[Qemu-devel] [PATCH for-2.1] qemu-iotests: fix 028 failure due to disk image path

[Stefan Hajnoczi]

The disk image path is echoed by QEMU's readline when the "drive_backup
disk ${TEST_IMG}.copy" HMP command is issued.  Unfortunately it is very
hard to filter out the path due to readline's character-by-character
output (with terminal escape sequences).  Just redirect this command to
/dev/null for now.
