Cloud Hypervisor v35.0 Released!
Posted September 21, 2023 by Cloud Hypervisor Team ‐ 2 min read
This release has been tracked in our roadmap project as iteration v35.0. The following user visible changes have been made:
virtio-vsock Support for Linux Guest Kernel v6.3+
Since kernel v6.3, a vsock packet can be included in a single descriptor,
instead of being split over two descriptors. Our virtio-vsock implementation
now support both situations.
User Specified Serial Number for virtio-block
A new option serial is added to the --block command that allows users to
specify a serial number for block devices which will be guest visible.
vCPU TSC Frequency Included in Migration State
This ensures migration works correctly between hosts that have different TSC frequencies if the guest is running with TSC as the source of timekeeping.
Notable Bug Fixes
- Disallow concurrent CPU resizing (#5668)
- Handle APIC EOI message for MSHV (#5681)
- Use wrapping add for memory offset from instruction emulator (#5719)
- Add global spell check via the ‘typos’ GitHub action (#5720)
- Ensure probing reads are block size aligned (#5727)
- Multiple bug fixes around the latency counter for block devices (#5712, #5750, #5762, #5763)
- Replace unsound
static mutwithonce_cell(#5772)
