- Update to version 52.0:
+ fix CVE-2026-45782
+ Confidential VM Support: KVM SEV-SNP
+ VFIO Device Passthrough via iommufd and vfio-cdev
+ Multi-Connection TCP Live Migration
+ Userfaultfd Demand-Paged Snapshot Restore
+ Configurable PCI BDFs for Devices
+ AIO Block Backend write_zeroes and punch_hole Support
+ Asynchronous QCOW2 Backend with io_uring
+ Generic vhost-user Device Support
+ Core Scheduling for vCPU Threads
+ Snapshot/Restore and Live Migration Improvements
+ New Command-Line and API Options
+ MSHV Support Improvements
+ Fix a guest-triggerable VMM panic
+ Saturate instead of underflowing on a malformed balloon actual
value reported by the guest
+ IOMMU address translation now returns errors instead of panicking
on malformed guest input
+ Several virtio device error paths now reset queues instead of
panicking or exiting the worker
+ Virtio barriers are now sized from the number of queues actually
activated by the guest, fixing pause hangs
+ PCI segment ACPI _UID values now match the segment ID
+ Fix VHDX multiqueue data corruption
+ Fix block-device resize-disk
+ Fix vdpa RX failure after device reset by always using base 0
+ Fix rebooting with landlock and a pty console
+ Reject rate limiting with vhost-user
+ Cancel vhost-user reconnection if the device has been unplugged
+ Remove the API socket path when start_vmm fails
+ Add missing ID validation for the virtio-rng device
+ Fix UB in MemoryRangeTable::read_from
+ DIO alignment is now queried directly from the underlying file
rather than assumed
+ QCOW2 metadata access is now thread-safe with num_queues > 1
+ Block devices unconditionally assume sparse support, matching
QEMU and avoiding a non-existent probe ioctl
+ Multi-value CLI options now use .action(ArgAction::Append) so
that repeating an option appends rather than replacing
+ AIO completions are batched in next_completed_request for the
block backend, reducing per-completion overhead
+ Fix O_DIRECT writes failing with EINVAL on the synchronous
QCOW2 backend
+ Fix O_DIRECT reads failing with EINVAL on the async io_uring
QCOW2 read path
+ Move QCOW2 compressed-cluster decompression out of the metadata
lock, removing a bottleneck for compressed images
+ Clamp the balloon's reported range to its region before
processing unused pages
+ Validate the requested balloon size against total guest RAM
+ Reject --memory-zone configurations that set both mergeable
and shared
+ Disable sector 0 writes for autodetected VHD images
