# v22.0
|
||||
|
||||
This release has been tracked through the [v21.0
|
||||
project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/24).
|
||||
|
||||
### GDB Debug Stub Support
|
||||
|
||||
Cloud Hypervisor can now be used as debug target with GDB. This is controlled
|
||||
by the `gdb` compile time feature and details of how to use it can be found in
|
||||
the [gdb
|
||||
documentation](https://github.com/cloud-hypervisor/cloud-hypervisor/blob/main/docs/gdb.md).
|
||||
|
||||
|
||||
### `virtio-iommu` Backed Segments
|
||||
|
||||
In order to facilitate hotplug devices that require being behind an IOMMU (e.g.
|
||||
QAT) there is a new option `--platform iommu_segments=<list_of_segments>` that
|
||||
will place all the specified segments behind the IOMMU.
|
||||
|
||||
### Before Boot Configuration Changes
|
||||
|
||||
It is now possible to change the VM configuration (e.g. add or remove devices,
|
||||
resize) before the VM is booted.
|
||||
|
||||
|
||||
### `virtio-balloon` Free Page Reporting
|
||||
|
||||
If `--balloon free_page_reporting=on` is used then the guest can report pages
|
||||
that is it not using to the VMM. The VMM will then notify the host OS that
|
||||
those pages are no longer in use and can be freed. This can result in improved
|
||||
memory density.
|
||||
|
||||
### Support for Direct Kernel Booting with TDX
|
||||
|
||||
Through the use of `TD-Shim` lightweight firmware it is now possible to
|
||||
directly boot into the kernel with TDX. The [TDX
|
||||
documentation](https://github.com/cloud-hypervisor/cloud-hypervisor/blob/main/docs/intel_tdx.md#tdshim)
|
||||
has been updated for this usage.
|
||||
|
||||
### PMU Support for AArch64
|
||||
|
||||
A PMU is now available on AArch64 for guest performance profiling. This will be
|
||||
exposed automatically if available from the host.
|
||||
|
||||
### Documentation Under CC-BY-4.0 Licese
|
||||
|
||||
The documentation is now licensed under the "Creative Commons Attribution 4.0
|
||||
International" license which is aligned with the project charter under the
|
||||
Linux Foundation.
|
||||
|
||||
### Deprecation of "Classic" `virtiofsd`
|
||||
|
||||
The use of the Rust based [virtiofsd](https://gitlab.com/virtio-fs/virtiofsd)
|
||||
is now recommended and we are no longer testing against the C based "classic"
|
||||
version.
|
||||
|
||||
### Notable Bug Fixes
|
||||
|
||||
* Can now be used on kernels without `AF_INET` support (#3785)
|
||||
* `virtio-balloon` size is now validated against guest RAM size (#3689)
|
||||
* Ensure that I/O related KVM VM Exits are correctly handled (#3677)
|
||||
* Multiple TAP file descriptors can be used for `virtio-net` device hotplug (#3607)
|
||||
* Minor API improvements and fixes (#3756, #3766, #3647, #3578)
|
||||
* Fix sporadic seccomp violation from glibc memory freeing (#3610, #3609)
|
||||
* Fix Windows 11 on AArch64 due to wider MSI-X register accesses (#3714, #3720)
|
||||
* Ensure `vhost-user` features are correct across migration (#3737)
|
||||
* Improved vCPU topology on AArch64 (#3735, #3733)

||||

### Efficient Local Live Migration (for Live Upgrade)
|
||||
|
||||
In order to support fast live upgrade of the VMM an optimised path has been added in which the memory for the VM is not compared from source to destination. This is activated by passing `--local` to the `ch-remote send-migration` command. This means that the live upgrade can complete in the order of 50ms vs 3s. (#3566)
