2016-04-15qemu-iotests: tests: do not set unused tmp variableSascha Silbe
The previous commit removed the last usage of ${tmp} inside the tests themselves; the only remaining users are sourced by check. So we can now drop this variable from the tests.

2015-11-11qemu-iotests: fix cleanup of background processesJeff Cody
Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash subshell, in order to catch segfaults. Unfortunately, this means the process PID cannot be captured via '$!'. We stopped killing qemu and qemu-nbd processes, leaving a lot of orphaned, running qemu processes after executing iotests. Since the process is using exec in the subshell, the PID is the same as the subshell PID. Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only track the qemu PID, however, if requested - not all usage requires killing the process.

2015-03-10iotests: Prepare for refcount_bits optionMax Reitz
Some tests do not work well with certain refcount widths (i.e. you cannot create internal snapshots with refcount_bits=1), so make those widths unsupported. Furthermore, add another filter to _filter_img_create in common.filter which filters out the refcount_bits value. This is necessary for test 079, which does actually work with any refcount width, but invoking qemu-img directly leads to the refcount_bits value being visible in the output; use _make_test_img instead which will filter it out.

2015-01-13qemu-iotests: Add "_supported_os Linux" to 058Fam Zheng
Other cases have this, and this test is not portable as well, as we want to add "make check-block" to "make check", it shouldn't fail on Mac OS X. Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2014-12-10qemu-iotests: Use qemu-io -f $IMGFMTKevin Wolf
This patch changes $QEMU_IO so that all tests by default pass a format argument to qemu-io. There are a few cases where -f $IMGFMT is not wanted because it selects the wrong driver or json: filenames including a driver are used. They are changed to use $QEMU_IO_PROG, which doesn't include any options. Tests 071 and 081 have output changes because now the actual request fails instead of reading the 2k probing buffer.

2013-12-04qemu-iotests: add 058 internal snapshot export with qemu-nbd caseWenchao Xia
This case can't run when IMGPROTO=nbd, since it needs to create some internal snapshot which would fail for EOF write request, even when TEST_IMG is exported with "-f raw" in common.rc, so set _supported_proto to file. _require_command() is changed to tip what util is missing, instead of printing a blank.
