[Qemu-devel] qemu-iotests failures for qcow and vpc

[Peter Wu <peter@lekensteyn.nl>]

Hi,

I just ran the qemu-iotests suite and found five failures in the vpc and
qcow block types.

The following command was executed with sources and objects in tmpfs:

    for i in qcow2 qed qcow generic vmdk raw vpc vhdx vdi \
             cow parallels cloop bochs; do
        ./check -c writeback -$i; done

QEMU version: v2.1.0-233-g8e6e2c2 plus patch "qemu-iotests: Fix 028
reference output for qed"[1].

Please find the results of failing tests below (`-c writeback` does not
affect the output).

Kind regards,
Peter
