[Qemu-devel] [PULL 1/9] qemu-iotests: add more tests to the "quick" group

[Stefan Hajnoczi]

From: Paolo Bonzini <pbonzini@redhat.com>

None of these needs QEMU_PROG, and they all take but a few seconds.
We need to point the launching script to qemu-nbd, though.

[Qemu-devel] [PULL 2/9] block: gluster - code movements, state storage changes

[Stefan Hajnoczi]

From: Jeff Cody <jcody@redhat.com>

In preparation for supporting reopen on gluster, move flag
parsing out to a function.  Also, add a NULL check in the
gconf cleanup.

[Qemu-devel] [PULL 3/9] block: gluster - add reopen support.

[Stefan Hajnoczi]

From: Jeff Cody <jcody@redhat.com>

Gluster does parse open flags in its .bdrv_open() implementation,
and the .bdrv_reopen_* implementations need to do the same.

A new gluster connection to the image file to be created is established
in the .bdrv_reopen_prepare(), and the image file opened with the new
flags.

If this is successful, then the old image file is closed, and the
old connection torn down. The relevant structure pointers in the gluster
state structure are updated to the new connection.

If it is not successful, then the new file handle and connection is
abandoned (if it exists), while the old connection is not modified at
all.

With reopen supported, block-commit (and offline commit) is now also
supported for image files whose base image uses the native gluster
protocol driver.

[Qemu-devel] [PULL 7/9] block: use /var/tmp instead of /tmp for -snapshot

[Stefan Hajnoczi]

From: Amit Shah <amit.shah@redhat.com>

If TMPDIR is not specified, the default was to use /tmp for the working
copy of the block devices.  Update this to /var/tmp instead, so systems
using tmp-on-tmpfs don't end up inadvertently using RAM for the block
device.
