#4687: Added VMGenID support for microVMs running on ARM hosts with 6.1 guest kernels. Support for VMGenID via DeviceTree bindings exists only on mainline 6.10 Linux onwards. Users of Firecracker will need to backport the relevant patches on top of their 6.1 kernels to make use of the feature.
#4732, #4733, #4741, #4746: Added official support for 6.1 microVM guest kernels.
Changed
Deprecated
Support for guest kernel 4.14 is now deprecated. We will completely remove 4.14 support with Firecracker version v1.10
Removed
#4689: Drop support for host kernel 4.14. Linux 4.14 reached end-of-life in January 2024. The minimum supported kernel now is 5.10. Guest kernel 4.14 is still supported.
Fixed
4680: Fixed an issue (#4659) where the virtio-net device implementation would always assume the guest accepts all VirtIO features the device offers. This is always true with the Linux guest kernels we are testing but other kernels, like FreeBSD make different assumptions. This PR fixes the emulation code to set the TAP features based on the features accepted by the guest.
