# v21.0
|
||||
|
||||
This release has been tracked through the [v21.0
|
||||
project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/24).
|
||||
|
||||
### 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)
|
||||
|
||||
### Recommended Kernel is Now 5.15
|
||||
|
||||
Due to an issue in the `virtio-net` code in 5.14 the recommended Linux kernel is now 5.15. (#3530)
|
||||
|
||||
### Notable Bug fixes
|
||||
|
||||
* Multiple fixes were made to the OpenAPI YAML file to match the implementaion (#3555,#3562)
|
||||
* Avoid live migration deadlock when triggered during the kernel boot (#3585)
|
||||
* Support live migration within firmware (#3586)
|
||||
* Validate the `virtio-net` desciptor chain (#3548)
|
||||
* `direct=on` (`O_DIRECT`) can now be used with a guest that makes unaligned accesses (e.g. firmware) (#3587)
|
||||

||||

# v20.2
|
||||
|
||||
This is a bug fix release. The following issues have been addressed:
|
||||
|
||||
* Don't error out when setting up the SIGWINCH handler (for console resize)
|
||||
when this fails due to older kernel (#3456)
|
||||
* Seccomp rules were refined to remove syscalls that are now unused
|
||||
* Fix reboot on older host kernels when SIGWINCH handler was not initialised
|
||||
(#3496)
|
||||
* Fix virtio-vsock blocking issue (#3497)
|
||||
|
||||
# v20.1
|
||||
|
||||
This is a bug fix release. The following issues have been addressed:
|
||||
|
||||
* Networking performance regression with `virtio-net` (#3450)
|
||||
* Limit file descriptors sent in `vfio-user` support (#3401)
|
||||
* Fully advertise PCI MMIO config regions in ACPI tables (#3432)
|
||||
* Set the TSS and KVM identity maps so they don't overlap with firmware RAM
|
||||
* Correctly update the `DeviceTree` on restore
