[libvirt] [PATCH] qemu: Fix domain resume after failed migration
by Jiri Denemark
Libvirt relies on being able to kill the destination domain and resume
the source one during migration until we called "cont" on the
destination. Unfortunately, QEMU automatically activates block devices
at the end of migration even when it's called with -S. This wasn't a big
issue in the past since the guest is not running and thus no data are
written to the block devices. However, when QEMU introduced its internal
block device locks, we can no longer resume the source domain once the
destination domain already activated the block devices (and thus
acquired all locks) unless the destination domain is killed first.
Since it's impossible to synchronize the destination and the source
libvirt daemons after a failed migration, QEMU introduced a new
migration capability called "late-block-activat" which ensures QEMU
won't activate block devices until it gets "cont". The only thing we
need to do is to enable this capability whenever QEMU supports it.
https://bugzilla.redhat.com/show_bug.cgi?id=1568407
QEMU commit implementing the capability: v2.12.0-952-g0f073f44df

[libvirt] [PATCH v2 0/3] Implement the HTM pSeries feature
by Andrea Bolognani
Applies cleanly on top of b1acfaaf890a16ecb2fecdbe7f121eff314dd0e9.
Changes from [v1]:
* drop qom-list-properties machinery, as equivalent functionality
has been merged in the meantime;
* don't introduce scaffolding for uniform machine option handling
as a requirement for implementing this specific feature: we can
do ad-hoc processing for now, per the status quo, then clean up
everything (including existing features) with a separate series
later.
Changes from [RFC v3]:
* can be considered for merging, since the QEMU part already has;
* fix compatibility issues with QEMU <2.12 spotted by Shivaprasad;
* drop all features except for HTM, at least for the time being;
* add documentation.
Changes from [RFC v2]:
* use qom-list-properties to probe availability;
* test all features with a single XML file.
Changes from [RFC v1]:
* don't nest features inside a <pseries/> element;
* implement all optional features.
