+ Offline migration transfers inactive definition of a domain (which
+ may or may not be active). After successful completion, the domain
+ remains in its current state on source host and is defined but
+ inactive on destination host. It's a bit more clever than
+ <code>virsh dumpxml</code> on source host followed by
+ <code>virsh define</code> on destination host, as offline migration
+ will run pre-migration hook to update the domain XML on destination
+ host. Currently, copying non-shared storage is not supported during
+ offline migration.

[libvirt] [PATCH 0/5] Fix async job type when doing external snapshots and improve error message handling
by Peter Krempa
This series adds error messages when trying to do a snapshot of a machine that
has hostdevices assigned.
Peter Krempa (5):
qemu: Restart CPUs with valid async job type when doing external
snapshots
qemu: Make qemuMigrationIsAllowed more reusable
qemu: snapshot: Report better error message if migration isn't
allowed
qemu: reuse qemuMigrationIsAllowed when doing save and managedsave
[OPTIONAL] qemu: allow save and managedsave on guests marked as
autodestroyable

[libvirt] [PATCH] qemu: assume seccomp sandbox is supported since qemu 1.2
by Ján Tomko
Currently there is no way to detect it via QMP and requesting "-sandbox
off" works correctly even if it was compiled out, so this will work
unless someone both requests the sandbox in qemu.conf and builds QEMU
without the support for it.

[libvirt] virDomainSetMetadata --> qemuDomainSetMetadata
by SHAH, Ronak (Ronak R)
Hi,
I have requirement to add <metadata> tag into the libvirt XML from the application.
While calling virDomainSetMetadata which internally call qemuDomainSetMetadata (correct me here if I am wrong),
I am getting following error:
qemuDomainSetMetdata:12623 : argument unsupported: QEMU driver does not support<metadata> element
Support for setting and getting <metadata> with special namespace is deliberately added in 0.9.10 of libvirt and I am using 0.9.13.
I am surprise that the internal qemu driver is still cribbing out it.
I am passing following in my call:
Type : VIR_DOMAIN_METADATA_ELEMENT
Metadata: "<desc> Some Desc </desc>"
Key: "Ronak"
uri: "Ronak.com/Ronak/libvirt"
Flags: 0
Can someone please help?
Thanks,
Ronak

[libvirt] [PATCH v3 0/8] Allow minimal bandwidth guarantee
by Michal Privoznik
This is a rework of my one year old patchset [1].
If you are brave enough and start reviewing it, you may want to read
the last patch first. The whole magic hidden behind the scene is
documented there. For now, the only supported combination where this
works is virtual interface connected to virtual network. This network
MUST have an inbound average set, at least. This tells how much
bandwidth do we have, and how much can we guarantee. If we would miss
this info, then we cannot guarantee anything. On the other hand, this
is just a very small part of whole problem. Users MUST configure all
other devices on traffic path to follow up their setting in libvirt.
But that's out of our scope.

[libvirt] [PATCH 0/8] parallels: add networking support
by Dmitry Guryanov
The goal of this patch series is to add initial support of
networking to Parallels Cloud Server driver.
Parallels driver will be able to show read-only list of virtual
networks and manage network adapters of virtual machines (list, add,
remove, change properties, switch to another virtual network).
Dmitry Guryanov (8):
parallels: parse information about network interfaces
parallels: add support of network interfaces to
parallelsDomainDefineXML
parallels: move parallelsParseError to parallels_utils.h
parallels: add network driver
Use size_t for virNetworkIpDef structure
parallels: parse virtual network properties
parallels: add routed pseudo network
parallels: handle network adapters of type 'routed'
