# v15.0
|
||||
|
||||
This release has been tracked through the [v15.0 project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/18).
|
||||
|
||||
Highlights for `cloud-hypervisor` version v15.0 include:
|
||||
|
||||
### Version numbering and stability guarantees
|
||||
|
||||
This release is the first in a new version numbering scheme to represent that
|
||||
we believe Cloud Hypervisor is maturing and entering a period of stability.
|
||||
With this new release we are beginning our new stability guarantees:
|
||||
|
||||
* The API (including command line options) will not be removed or changed in a
|
||||
breaking way without a minimum of 2 releases notice. Where possible warnings
|
||||
will be given about the use of deprecated functionality and the deprecations
|
||||
will be documented in the release notes.
|
||||
* Point releases will be made between individual releases where there are
|
||||
substantial bug fixes or security issues that need to be fixed.
|
||||
|
||||
Currently the following items are **not** guaranteed across updates:
|
||||
|
||||
* Snapshot/restore is not supported across different versions
|
||||
* Live migration is not supported across different versions
|
||||
* The following features are considered experimental and may change
|
||||
substantially between releases: TDX, SGX.
|
||||
|
||||
### Network device rate limiting
|
||||
|
||||
Building on our existing support for rate limiting block activity the network
|
||||
device also now supports rate limiting. Full details of the controls are in the
|
||||
[IO throttling documentation.](docs/io_throttling.md)
|
||||
|
||||
### Support for runtime control of `virtio-net` guest offload
|
||||
|
||||
The guest is now able to change the offload settings for the `virtio-net`
|
||||
device. As well as providing a useful control this mitigates an issue in the
|
||||
Linux kernel where the guest will attempt to reprogram the offload settings
|
||||
even if they are not advertised as configurable (#2528).
|
||||
|
||||
### `--api-socket` supports file descriptor parameter
|
||||
|
||||
The `--api-socket` can now take an `fd=` parameter to specify an existing file
|
||||
descriptor to use. This is particularly beneficial for frameworks that need to
|
||||
programmatically control Cloud Hypervisor.
|
||||
|
||||
### Bug fixes
|
||||
|
||||
* A workaround has been put in place to mitigate a Linux kernel issues that
|
||||
results in the CPU thread spinning at 100% when using `virtio-pmem` (#2277).
|
||||
* PCI BARs are now correctly aligned removing the need for the guest to
|
||||
reprogram them (#1797,#1798)
|
||||
* Handle TAP interface not being writable within virtio-net (due to the buffer
|
||||
exhaustion on the host) (#2517)
|
||||
* The recommended Linux kernel is now v5.12.0 as it contains a fix that
|
||||
prevents snapshot & restore working (#2535)
|
||||
|
||||
### Deprecations
|
||||
|
||||
Deprecated features will be removed in a subsequent release and users should plan to use alternatives
|
||||
|
||||
* Support for booting with the "LinuxBoot" protocol for ELF and `bzImage`
|
||||
binaries has been deprecated. When using direct boot users should configure
|
||||
their kernel with `CONFIG_PVH=y`. Will be removed in v16.0.
|
||||

||||

# v0.14.1
|
||||
|
||||
Bug fix release branched off the v0.14.0 release. The following bugs were fixed
|
||||
in this release:
|
||||
|
||||
* CPU hotplug on Windows failed due to misreported CPU state information and
|
||||
the lack of HyperV CPUID bit enabled (#2437, #2449, #2436)
|
||||
* A seccomp rule was missing that was triggered on CPU unplug (#2455)
|
||||
* A bounds check in VIRTIO queue validation was erroneously generating
|
||||
DescriptorChainTooShort errors in certain circumstances (#2450, #2424)
|
||||
|
||||
# v0.14.0
|
||||
|
||||
This release has been tracked through the [0.14.0 project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/17).
