Hi all,
as planned I just tagged the new release in git, and pushed signed tarball
and rpms to the usual place:
ftp://libvirt.org/libvirt/
I also pushed the python bindings, identical to 4.10 with just the versioning
bump, you can find them at:
ftp://libvirt.org/libvirt/python/
This release includes new features, but also remove the old apparently unused
UML driver support. There is also a rather large set of improvements:
New features:
- Xen: Add support for openvswitch
The libxl driver now supports virtual interfaces that connect to an
openvswitch bridge, including interfaces with VLAN tagging and trunking
configuration.
- qemu: Report whether KVM nesting is available
Running nested KVM guests requires specific configuration steps to be
performed on the host; libvirt will now report in the host capabilities
whether KVM nesting support is available.
Removed features:
- Drop UML driver
The UML driver was unmaintained and not tested for quite some time now.
Worse, there is a bug that causes it to deadlock on some very basic
operations (e.g. dumping domain XML). These facts make us believe no
one uses it.
Improvements:
- qemu: Add support for ARMv6l guests
- Support more NVDIMM configuration options
Introduce more configuration options. For the source element, add the
'alignsize' and 'pmem' subelements. For the target element, add the
'readonly' subelement.
- cpu: Add support for "stibp" x86_64 feature
Add cpu flag stibp (Single Thread Indirect Branch Predictors) to
prevent indirect branch predictions from being controlled by the
sibling Hyperthread.
- libxl: Handle external domain destroy
Historically, if a domain was destroyed using xl rather than through
libvirt APIs, libvirt would not be aware of the fact and keep
considering it as running. This is no longer the case.
- Start selecting the first available DRI device for OpenGL operations
If OpenGL support is needed (either with SPICE gl enabled or with
egl-headless), libvirt is now able to pick the first available DRI
device for the job. At the same time, this improvement is also a bugfix
as it prevents permission-related issues with regards to our mount
namespaces and the default DRI render node's permissions which would
normally prevent QEMU from accessing such a device.
- qemu: Add support for postcopy-requests migration statistics
The virDomainJobInfo can get number page requests received from the
destination host during post-copy migration.
Bug fixes:
- lxc: Don't forbid interfaces with type=direct
Such interfaces are supported by lxc and should be allowed.
- qemu: Fully clean up RNG devices on detach
Some RNG device types, such as those using EGD, might need extra clean
up on the host in addition to removing the guest-side device.
Thanks everybody for your help toward this release, be it with patches
reviews, bug description, documentation and localizations !
As a reminder, the next release is scheduled at the end of February,
in the meantime, enjoy the new release !
Daniel
