<!-- libvirt release notes
|
|
|
|
This file will be processed to produce both HTML and plain text versions
|
|
of the release notes.
|
|
|
|
Keep the style consistent with existing entries as much as possible.
|
|
|
|
Each change should be documented by a short, one-sentence summary, which
|
|
should fit in a single line and should not contain any formatting tags.
|
|
|
|
You can optionally add a description if you feel like the summary alone is
|
|
not enough to document the change accurately. The description may contain
|
|
a <code> tag for switching to non-proportional font. No other tags are
|
|
allowed.
|
|
|
|
Lines should be kept under 80 columns, and should not exceed 100 columns.

QEMU 2.10 will be able to report the reason for shutting

down (whether that was caused by the guest or not), and
|
|
libvirt is prepared for that and reports that information in
|
|
its shutdown event as well, if it is known.

qemu: Use GICv2 by default for aarch64/virt TCG guests

</summary>

<description>

|
The emulated GICv3 has some limitations that make it unusable as a

default; use GICv2 until they're sorted out. This change makes it
|
|
once again possible to run aarch64/virt guests on a x86_64 host
|
|
without having to tweak their configuration.

When error occurred in a specific point in time during the

hot-plug of an RNG device, it could happen that an address

|
was released even though another device was already using
|
|
it, making it possible to hot-plug another device with that
|
|
address, effectively having duplicated addresses in the XML.

<description>
|
|
When using thin provisioning, management tools need to resize the

disk in certain cases. To avoid having them to poll disk usage
|
|
this version introduces an event which will be fired when a given
|
|
offset of the storage is written by the hypervisor. Together with the
|
|
API it allows registering thresholds for given storage backing
|
|
volumes and this event will then notify management if the threshold
|
|
is exceeded. Currently only the qemu driver supports this.

QEMU: Use adaptive timeout for connecting to monitor
|
|
</summary>
|
|
<description>
|
|
When starting qemu, libvirt waits for qemu to create the monitor
|
|
socket which libvirt connects to. Historically, there was sharp 30
|
|
second timeout after which the qemu process was killed. This
|
|
approach is suboptimal as in some scenarios with huge amounts of
|
|
guest RAM it can take a minute or more for kernel to allocate and
|
|
zero out pages for qemu. The timeout is now flexible and computed by
|
|
libvirt at domain startup.

nodedev: Fabric name must not be required for fc_host capability
|
|
</summary>
|
|
<description>
|
|
fabric_name is one of many fc_host attributes in Linux that is
|
|
optional and left to the low-level driver to decide if it is
|
|
implemented. For example the zfcp device driver does not provide a
|
|
fabric name for an fcp host. The requirement for the existence of
|
|
a fabric name has been removed by making it optional.

bhyve: change address allocation schema for SATA disks
|
|
</summary>
|
|
<description>
|
|
Previously, the bhyve driver assigned PCI addresses to SATA disks
|
|
directly rather than assigning that to a controller and
|
|
using SATA addresses for disks. It was implemented this way
|
|
because bhyve has no notion of an explicit SATA controller.
|
|
However, as this doesn't match libvirt's understanding of
|
|
disk addresses, the bhyve driver was changed to follow
|
|
the common schema and have PCI addresses for SATA controllers
|
|
and SATA addresses for disks. If you're having issues
|
|
because of this, it's recommended to edit the domain's XML
|
|
and remove <address type='pci'> from the <disk>
|
|
elements with <target bus='sata'/> and let libvirt
|
|
regenerate it properly.

qemu: aggregate pcie-root-ports onto multiple functions of a slot

|

<description>
|
|
When pcie-root-ports are added to pcie-root in order to
|
|
provide a place to connect PCI Express endpoint devices,
|
|
libvirt now aggregates multiple root ports together onto the
|
|
same slot (up to 8 per slot) in order to conserve slots.
|
|
Using this method, it's possible to connect more than 200
|
|
endpoint devices to a guest that uses PCIe without requiring
|
|
setup of any PCIe switches.
