[libvirt] [PATCH] Deprecate several CURRENT/LIVE/CONFIG enums
by Hu Tao
This patch deprecates following enums:
VIR_DOMAIN_MEM_CURRENT
VIR_DOMAIN_MEM_LIVE
VIR_DOMAIN_MEM_CONFIG
VIR_DOMAIN_VCPU_LIVE
VIR_DOMAIN_VCPU_CONFIG
VIR_DOMAIN_DEVICE_MODIFY_CURRENT
VIR_DOMAIN_DEVICE_MODIFY_LIVE
VIR_DOMAIN_DEVICE_MODIFY_CONFIG
And modify internal codes to use virDomainModifycationImpact.

[libvirt] RFC (v4): Add virDomainBlockPull API family to libvirt
by Adam Litke
This round addresses all review comments from the last posting and should be
ready for inclusion. Thanks for the review.
Changes since V3:
- Don't check flags at the libvirt API level
- qemu: Check disk->type before looking up alias
- virsh: Merge blockpullall into blockpull
- event: Drop events for unknown disk paths
- Misc style fixes and comment updates
Changes since V2:
- Rebased
- Ensure error messages are consistent between JSON and Text interfaces
- Added additional tests to the sample test bucket
Changes since V1:
- Rebased to incorporate changes to generator and
removal of static driver structure initializers
- Other small fixups suggested by Matthias Bolte
To help speed the provisioning process for large domains, new QED disks are
created with backing to a template image. These disks are configured with copy
on read such that blocks that are read from the backing file are copied to the
new disk. This reduces I/O over a potentially costly path to the backing
image.
In such a configuration, there is a desire to remove the dependency on the
backing image as the domain runs. To accomplish this, qemu will provide an
interface to perform sequential copy on read operations during normal VM
operation. Once all data has been copied, the disk image's link to the backing
file is removed.
The virDomainBlockPull API family brings this functionality to libvirt.
virDomainBlockPullAll() instructs the hypervisor to stream the entire device in
the background. Progress of this operation can be checked with the function
virDomainBlockPullInfo(). An ongoing stream can be cancelled with
virDomainBlockPullAbort(). If a more controlled IO rate is desired,
virDomainBlockPull() can be used to perform a single increment of IO.
Subsequent calls to this function will automatically stream the appropriate
next increment until the disk has been fully populated.
An event (VIR_DOMAIN_EVENT_ID_BLOCK_PULL) will be emitted when a disk has been
fully populated or if a BlockPullAll() operation was terminated due to an
error. This event is useful to avoid polling on virDomainBlockPullInfo() for
completion and could also be used by the security driver to revoke access to
the backing file when it is no longer needed.
make check: PASS
make syntax-check: PASS
make -C tests valgrind: PASS
I am testing this API with Python Unittest (see the last patch).
[PATCH 1/8] Add new API virDomainBlockPull* to headers
[PATCH 2/8] virDomainBlockPull: Implement the main entry points
[PATCH 3/8] Add virDomainBlockPull support to the remote driver

[libvirt] [PATCH] sendkey: use consistent API convention
by Eric Blake
Even though rpc uses 'unsigned int' for the _val parameter that
passes the length of item<length>, the public libvirt APIs all
use 'int' and filter out lengths < 0, except for virDomainSendKey.
* include/libvirt/libvirt.h.in (virDomainSendKey): All other APIs
use int for array length.
* src/libvirt.c (virDomainSendKey): Adjust.
* src/driver.h (virDrvDomainSendKey): Likewise.
* daemon/remote_generator.pl: Likewise.
---
One approach to a question first raised here.
https://www.redhat.com/archives/libvir-list/2011-June/msg00681.html
The other approach would be to change all libvirt API to use
unsigned int for array sizes, to match rpc conventions and to
simplify code to not have to worry about negative sizes, but
that is more invasive.

by Matthias Bolte
Commit 64000eabedf2 is part 1, that only covered the daemon side by

[libvirt] [PATCH] remote generator: Handle struct returning functions better
by Matthias Bolte
The position of the struct parameter in the function signature
differs. Instead of hardcoding the handling for this add an annotation
to the .x file to define the position.

[libvirt] [PATCH] qemu: domain I/O asynchronous handling
by Michal Privoznik
For virtio disks and interfaces, qemu allows users to enable or disable
ioeventfd feature. This means, qemu can execute domain code, while
another thread waits for I/O event. Basically, in some cases it is win,
in some loss. This feature is available via 'asyncio' attribute in disk
and interface <driver> element. It accepts 'on' and 'off'. Leaving this
attribute out defaults to hypervisor decision.
---
this is rework as suggested:
