[libvirt] [PATCH V2] Expose resource control capabilites on cache bank
by Eli Qiao
This patch is based on Martin's cache branch.
This patch amends the cache bank capability as follow:
<cache>
<bank id='0' level='3' type='unified' size='15360' unit='KiB' cpus='0-5'/>
<control min='768' unit='KiB' type='unified' nallocations='4'/>
<bank id='1' level='3' type='unified' size='15360' unit='KiB' cpus='6-11'/>
<control min='768' unit='KiB' type='unified' nallocations='4'/>
</cache>
Along with vircaps2xmltest case updated.

[libvirt] [PATCHv2] Split out -Wframe-larger-than warning from WARN_CLFAGS
by Ján Tomko
Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
the library code and RELAXED_FRAME_LIMIT_CFLAGS for daemon code
and the test code.
Raising the limit for tests allows building them with clang
with optimizations disabled.

[libvirt] [PATCH] leasetime support per <dhcp> and <host>
by Alberto Ruiz
Support for custom dhcp wide and per host leasetime.
It is specified as a child tag for <dhcp>:
<dhcp>
<leasetime>24h</leasetime>
...
</dhcp>
And as an attribute for <host>:
<dhcp>
<host leasetime="7d" .../>
</dhcp>
These are the different notations:
-1 (infinite/unlimited lease)
120 (seconds are the default unit, 120 seconds is the minimum, if less is
specified it will use 120)
300s (seconds)
5m (minutes)
24h (hours)
7d (days)

[libvirt] [PATCH] qemu: Move some functions to qemu_capspriv.h
by Andrea Bolognani
This header file has been created so that we can expose
internal functions to the test suite without making them
public: those in qemu_capabilities.h bearing the comment
/* Only for use by test suite */
are obvious candidates for being moved over.

[libvirt] [PATCH v2] storage: Avoid leak in virStorageUtilGlusterExtractPoolSources()
by Andrea Bolognani
The contents of volname would be leaked if the function were
to be passed an invalid pooltype by the caller.
Make sure the memory is released instead.

Changes from v1:
* use VIR_STEAL_PTR() instead of open-coding it.

Initializing volname to NULL is strictly speaking not
necessary, but I like it better that way :)

[libvirt] [PATCH] qemu: Properly reset TLS in qemuProcessRecoverMigrationIn
by Jiri Denemark
There is no async job running when a freshly started libvirtd is trying
to recover from an interrupted incoming migration. While at it, let's
call qemuMigrationResetTLS every time we don't kill the domain. This is
not strictly necessary since TLS is not supported when v2 migration
protocol is used, but doing so makes more sense.
