From 70a5ff6bdd2f0d4c22e216cab921f9288cb1656e Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 24 Oct 2014 12:58:00 +0200 Subject: iotests: Add test for external image truncation It should not be happening, but it is possible to truncate an image outside of qemu while qemu is running (or any of the qemu tools using the block layer. raw_co_get_block_status() should not break then. While touching this test, replace the existing "truncate" invocation by "$QEMU_IMG convert -f raw".
