hyperv: Implement virDomainSetMemory and virDomainSendKey APIs
qemu: Support multiple PHBs for pSeries guests pSeries guests can now have multiple PHBs (PCI Host Bridges), which show up as separate PCI domains in the guest. To create additional PHBs, simply add PCI controllers with model pci-root to the guest configuration.
qemu: Isolate hostdevs on pSeries guests To enable better error reporting and recovery, unrelated hostdevs will now be automatically isolated on pSeries guests by placing them on separate PHBs (PCI Host Bridges).
Improvements
qemu: platform serial devices can now use chardev features QEMU VMs that depend on platform serial devices can now use QEMU's -chardev option, which enables access to advanced features like log file configuration. This applies to the default serial devices for arm, aarch64, and some ppc configurations.
Require use of GCC 4.4 or Clang compilers We only ever test libvirt with GCC or Clang (which provides a GCC compatible compilation environment). Between them, these compilers cover every supported operating system platform, including Windows.
qemu: shared disks with directsync cache should be safe for migration At present shared disks can be migrated with either readonly or cache=none. But cache=directsync should be safe for migration, because both cache=directsync and cache=none don't use the host page cache, and cache=direct write through qemu block layer cache.
Handle hotplug change on VLAN configuration using OVS Libvirt was taught to handle VLAN change for running OVS interface.
Bug fixes
qemu: Use vCPU 'node-id' property and pass it back to qemu vCPU properties gathered from query-hotpluggable-cpus need to be passed back to QEMU. As QEMU did not use the node-id property until now and libvirt forgot to pass it back properly (it was parsed but not passed around) we did not honor this.
Miscellaneous stream fixes After introducing sparse stream features there were still some known bugs left. Those are fixed in this release.
qemu: Miscellaneous domain NS fixes Libvirt starts qemu domains in separate Linux namespaces for a while now. However, there were still some bugs lingering. For instance libvirt did not know how to handle file based bind mounts.
Various CPU driver improvements There were some minor bugs when using 'host-model' CPU.
