[Qemu-devel] [PATCH 01/10] virtio: Factor virtqueue_map_sg out

[Kevin Wolf]

Separate the mapping of requests to host memory from the descriptor iteration.
The next patch will make use of it in a different context.

[Qemu-devel] [PATCH 02/10] virtio-blk: Fix migration of queued requests

[Kevin Wolf]

in_sg[].iovec and out_sg[].ioved are pointer to (source) host memory and
therefore invalid after migration. When loading the device state we must
create a new mapping on the destination host.

[Kevin Wolf]

Arguably we should re-open the backing file with the backing file format and
not with the format of the snapshot image.

[Qemu-devel] [PATCH 04/10] sheepdog: remove unnecessary includes

[Kevin Wolf]

From: Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>

"qemu_socket.h" includes all necessary files and
including <netinet/tcp.h> without <netinet/in.h>
could cause errors on some systems.

[Qemu-devel] [PATCH 05/10] qemu-img rebase: Open new backing file read-only

[Kevin Wolf]

We never write to a backing file, so opening rw is useless. It just means that
you can't rebase on top of a file for which you don't have write permissions.

[Qemu-devel] [PATCH 07/10] nbd: Introduce NBD named exports.

[Kevin Wolf]

From: Laurent Vivier <laurent@vivier.eu>

This patch allows to connect Qemu using NBD protocol to an nbd-server
using named exports.

For instance, if on the host "isoserver", in /etc/nbd-server/config, you have:

[generic]
[debian-500-ppc-netinst]
        exportname = /ISO/debian-500-powerpc-netinst.iso
[Fedora-10-ppc-netinst]
        exportname = /ISO/Fedora-10-ppc-netinst.iso

You can connect to it, using:

    qemu -cdrom nbd:isoserver:exportname=debian-500-ppc-netinst
    qemu -cdrom nbd:isoserver:exportname=Fedora-10-ppc-netinst

NOTE: you need at least nbd-server 2.9.18

[Qemu-devel] [PATCH 09/10] monitor: make 'info snapshots' show only fully available snapshots

[Kevin Wolf]

From: Miguel Di Ciurcio Filho <miguel.filho@gmail.com>

The output generated by 'info snapshots' shows only snapshots that exist on the
block device that saves the VM state. This output can cause an user to
erroneously try to load an snapshot that is not available on all block devices.

$ qemu-img snapshot -l xxtest.qcow2

Snapshots 1 and 2 do not exist on xxtest2.qcow, but they are displayed anyway.

This patch sumarizes the output to only show fully available snapshots.

New output:

[Qemu-devel] [PATCH 10/10] savevm: Generate a name when run without one

[Kevin Wolf]

From: Miguel Di Ciurcio Filho <miguel.filho@gmail.com>

When savevm is run without a name, the name stays blank and the snapshot is
saved anyway.

The new behavior is when savevm is run without parameters a name will be
created automaticaly, so the snapshot is accessible to the user without needing
the id when loadvm is run.

(qemu) savevm
(qemu) info snapshots
ID        TAG                 VM SIZE                DATE       VM CLOCK
1         vm-20100728134640      978K 2010-07-28 13:46:40   00:00:08.603

We use a name with the format 'vm-YYYYMMDDHHMMSS'.

This is a first step to hide the internal id, because I don't see a reason to
expose this kind of internals to the user.

Anthony, I think you already pulled the patches for stable-0.13 that I
