[libvirt] [PATCH] selinux: Don't fail RestoreAll if file doesn't have a default label
by Cole Robinson
When restoring selinux labels after a VM is stopped, any non-standard
path that doesn't have a default selinux label causes the process
to stop and exit early. This isn't really an error condition IMO.
Of course the selinux API could be erroring for some other reason
but hopefully that's rare enough to not need explicit handling.
Common example here is storing disk images in a non-standard location
like under /mnt.

[libvirt] [PATCHv2 00/11] util: add VIR_(INSERT|DELETE)_ELEMENTS_N
by Laine Stump
This is a repost of
https://www.redhat.com/archives/libvir-list/2012-October/msg01080.html
with PATCH 03/12 squashed into 01/12. There are no other changes.
************************************
PATCH 01/11 defines a couple new macros/functions to simplify
inserting/deleting items in the middle of an array. The remaining
patches switch over various pieces of existing code to use these new
macros rather than directly calling memmove, etc.
There are several other places where these macros could *almost* be
used, except that they use the model of pre-allocating the larger
array, then performing a bunch of operations (that may fail) and then
finally move items around in the array and adjust its count. I'm
wondering if I should add a flags arg to these to allow for specifying
a "Don't realloc" flag - when it was given, the memory allocation
operation would be presumed already done (in the case of insert) or to
be done after return (for delete). Any opinions on that? (such as
maybe "that's too many options!")

[libvirt] [PATCH] Add device operations for lxc.
by Heiher
Operations:
1. lxcDomainAttachDevice
2. lxcDomainAttachDeviceFlags
3. lxcDomainDetachDevice
4. lxcDomainDetachDeviceFlags
5. lxcDomainUpdateDeviceFlags
In live mode, set devices.allow/deny to instance's cgroup and insert
disk config into current domain.
In config mode, just insert disk config into current domain.

[libvirt] [PATCH] Add cpu thread siblings information to virsh capabilities.
by Dusty Mabe
This patch is an attempt to add cpu hyperthreaded siblings information
to the output from virsh capabilities output. The information will
directly mirror the contents of the
/sys/devices/system/cpu/cpuN/topology/thread_siblings_list
files. The new output of virsh capabilities will look like:
<topology>
<cells num='2'>
<cell id='0'>
<cpus num='12'>
<cpu id='0' thread_siblings='0,12'/>
.
.
</cpus>
</cell>
</cells>
</topology>
This patch is my first attempt at patching libvirt so forgive me if I
make some novice mistakes.

[libvirt] [PATCH] Refactor ESX storage driver and add iSCSI support
by Ata E Husain Bohra
The patch refactors the current ESX storage driver due to following reasons:
1. Given most of the public APIs exposed by the storage driver in Libvirt
remains same, ESX storage driver should not implement logic specific
for only one supported format (current implementation only supports VMFS).
2. Decoupling interface from specific storage implementation gives us an
extensible design to hook implementation for other supported storage
formats.
This patch refactors the current driver to implement it as a facade pattern i.e.
the driver exposes all the public libvirt APIs, but uses backend drivers to get
the required task done. The backend drivers provide implementation specific to
the type of storage device.
File changes:
------------------
esx_storage_driver.c ----> esx_storage_driver.c (base storage driver)
|
|---> esx_storage_backend_vmfs.c (VMFS backend)
|
|---> esx_storage_backend_iscsi.c (iSCSI backend)
The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:
1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs <------> Libvirt Storage Volumes.
The above understanding is based on http://libvirt.org/storage.html.
The operation supported on iSCSI pools includes:
1. List storage pools & volumes.
2. Get xml descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, uuid and path (if applicable).
iSCSI pools does not support operations such as: Create / remove pools
and volumes

[libvirt] [PATCHv5 0/3] Transport Open vSwitch per-port data during live migration
by Laine Stump
In-Reply-To:
This is an update (of an update :-) of Kyle Mestery's patch series v3
by the same name:
https://www.redhat.com/archives/libvir-list/2012-October/msg00014.html
I've updated it according to the comments in the review of patch 1/3
of that series:
https://www.redhat.com/archives/libvir-list/2012-October/msg01224.html
and also according to Michal and Eric's comments on v4:
https://www.redhat.com/archives/libvir-list/2012-October/msg01227.html
(interdiffs for those last changes are attached to patches 1/3 and 2/3)
It now needs a counter-review from Kyle, along with verification that
it actually works (since I don't have the proper setup to test it
handy).
******************************************
This series of commits has the end goal of allowing per-port data stored
in the Open vSwitch DB to be transported during live migration. This is
done by first providing a generic infrastructure for transporting network
data, adding some utility functions specific to Open vSwitch, and hooking
the two together.
The framework provided is generic in that other networking data could be
transferred as well by simply adding in additional hooks as needed.
Kyle Mestery (3):
Add the ability for the Qemu V3 migration protocol to include
transporting network configuration. A generic framework is proposed
with this patch to allow for the transfer of opaque data.
Add utility functions for Open vSwitch to both save per-port data
before a live migration, and restore the per-port data after a
live migration.
Transport Open vSwitch per-port data during live migration by
using the utility functions
virNetDevOpenvswitchGetMigrateData() and
virNetDevOpenvswitchSetMigrateData().
****************************************************************
interdiff for PATCH 1/3:
* remove extra {} in one place, add them in a couple others (I like
braces when the condition is multi-line too).
* don't emit <network> element at all if all the vporttypes are NONE
* fix position of [i] in comment

[libvirt] [PATCH] Fix detection of Xen sysctl version 9
by Jim Fehlig
In commit 371ddc98, I mistakenly added the check for sysctl
version 9 after setting the hypercall version to 1, which will
fail with
error : xenHypervisorDoV1Op:967 : Unable to issue hypervisor
ioctl 3166208: Function not implemented
This check should be included along with the others that use
hypercall version 2.

[libvirt] [PATCH 00/12] util: add VIR_(INSERT|DELETE)_ELEMENTS_N
by Laine Stump
PATCH 01/12 defines a couple new macros/functions to simplify
inserting/deleting items in the middle of an array. The remaining
patches switch over various pieces of existing code to use these new
macros rather than directly calling memmove, etc.
There are several other places where these macros could *almost* be
used, except that they use the model of pre-allocating the larger
array, then performing a bunch of operations (that may fail) and then
finally move items around in the array and adjust its count. I'm
wondering if I should add a flags arg to these to allow for specifying
a "Don't realloc" flag - when it was given, the memory allocation
operation would be presumed already done (in the case of insert) or to
be done after return (for delete). Any opinions on that?
