This adds tests for live snapshots, both through the single
snapshot command, and the transaction group snapshot command.
The snapshots are done through the QMP interface, using the
following commands for snapshots:
Single snapshot:
{ 'execute': 'blockdev-snapshot-sync', 'arguments':
{ 'device': 'virtio0', 'snapshot-file':'...',
'format': 'qcow2' } }"
Group snapshot:
{ 'execute': 'transaction', 'arguments':
{'actions': [
{ 'type': 'blockdev-snapshot-sync', 'data' :
{ 'device': 'virtio0', 'snapshot-file': '...' } },
{ 'type': 'blockdev-snapshot-sync', 'data' :
{ 'device': 'virtio1', 'snapshot-file': '...' } } ]
} }

=== This is the QEMU I/O test suite ===
* Intro
This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries. This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.
* Usage
Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format. The output of ./check -h explains
additional options to test further image formats or I/O methods.
* Feedback and patches
Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@savannah.nongnu.org.
