This series adds the image streaming test suite to qemu-iotests. It covers the
'block_stream', 'block_job_cancel', 'block_job_set_speed', and
'query-block-jobs' QMP interfaces.
Since these tests involve QMP it is no longer convenient to write them in bash.
Instead these tests are written in Pytho
Since qemu-iotests may need to create large image files it is possible
to specify the test directory. The TEST_DIR variable needs to be
exported so non-bash tests can make use of it.

Block layer tests that involve QMP commands rather than qemu-img or
qemu-io are not well-suited for shell scripting. This patch adds a
Python module which allows tests to be written in Python instead.
The basic API is:
VM - class for launching and interacting with a VM
QMPTestCase -
This patch adds a test suite for the image streaming feature. It
exercises the 'block_stream', 'block_job_cancel', 'block_job_set_speed',
and 'query-block-jobs' QMP commands.

Hi Stefan.
Wireshark supports a lot more than just SCSI over iSCSI
It dissects SCSI over USB, FCOE, raw-FC, FCIP, iFCP (I never got

I never got access to HyperSCSI traces either, so that is missing too.

Before this patch the ehci code was not checking for any other errors other

When creating an USB device the old way, there is no way to specify the
target bus. Thus the warning issued by usb_create makes no sense and
rather confuses our users.
Resolve this by passing a bus reference to the usbdevice_init handler
and letting those handlers forward it to
Hi,
Next batch of usb updates. This one brings packet queuing for uhci and
xhci, so we have per-endpoint queues at usb-bus level now. Need to
bring those to the usb drivers as next step, so they (especially
usb-host) can pipeline requests.
Also a bunch of bugfixes in ehci, smartcard emulation
This removes quite some duplicated code.

As the command name implies, this command suspends the guest to disk.
The suspend operation is implemented by two functions: bios_supports_mode()
and guest_suspend(). Both functions are generic enough to be used by
other suspend modes (introduced by next commits).
Both functions will try to use t

This adds the QMP command for blockdev-group-snapshot-sync. It
takes an array in as the input, for the argument devlist. The
array consists of the following elements:
+ device:device to snapshot. e.g. "ide-hd0", "virtio0"
+ snapshot-file: path & file for the snapshot image. e.g. "
This is a QAPI/QMP only command to take a snapshot of a group of
devices. This is similar to the blockdev-snapshot-sync command, except
blockdev-group-snapshot-sync accepts a list devices, filenames, and
formats.
It is attempted to keep the snapshot of the group atomic; if the
