# v51.0
|
||||
|
||||
This release has been tracked in [v51.0
|
||||
group](https://github.com/orgs/cloud-hypervisor/projects/6/views/6?filterQuery=release%3A%22Release+51%22)
|
||||
of our [roadmap project](https://github.com/orgs/cloud-hypervisor/projects/6/).
|
||||
|
||||
### Security Fixes
|
||||
|
||||
This release fixes a security vulnerability in disk image handling.
|
||||
Details can be found in
|
||||
[GHSA-jmr4-g2hv-mjj6](https://github.com/cloud-hypervisor/cloud-hypervisor/security/advisories/GHSA-jmr4-g2hv-mjj6).
|
||||
|
||||
* A new `backing_files=on|off` option has been added to `--disk` to
|
||||
explicitly control whether QCOW2 backing files are permitted. This
|
||||
defaults to `off` to prevent the loading of backing files entirely.
|
||||
(#7685)
|
||||
* Explicit image type specification via the user interface, removing
|
||||
reliance on format autodetection (#7728).
|
||||
* Prevent sector-zero writes for autodetected raw images (#7728).
|
||||
|
||||
### Significant QCOW2 v3 Improvements
|
||||
|
||||
A large number of QCOW2 v3 specification features have been implemented:
|
||||
|
||||
* RAW backing file support for QCOW2 overlays (#7570)
|
||||
* Zero bit in L2 entries (#7627)
|
||||
* Incompatible feature bit validation (#7612)
|
||||
* Dirty bit support (#7636)
|
||||
* Variable refcount widths (1 to 64-bit) (#7633)
|
||||
* Corrupt bit detection and marking (#7639)
|
||||
* Autoclear feature bits handling (#7648)
|
||||
* Thread safety fix for multiple virtio queues (`num_queues > 1`)
|
||||
(#7661)
|
||||
* Correct zero-fill for reads beyond backing file size (#7678)
|
||||
* Live disk resize support (#7687)
|
||||
|
||||
### ACPI Generic Initiator Support
|
||||
|
||||
ACPI Generic Initiator Affinity (SRAT Type 5) support has been added
|
||||
to associate VFIO-PCI devices with dedicated memory/CPU-less NUMA
|
||||
nodes. This enables the guest OS to make NUMA-aware memory allocation
|
||||
decisions for device workloads. A new `device_id` parameter has been
|
||||
added to `--numa` for specifying VFIO devices. (#7626)
|
||||
|
||||
### Block Device DISCARD and WRITE_ZEROES Support
|
||||
|
||||
The `virtio-blk` device now supports `DISCARD` and `WRITE_ZEROES`
|
||||
operations for QCOW2 and RAW image formats. This enables thin
|
||||
provisioning and efficient space reclamation when guests trim
|
||||
filesystems. A new `sparse=on|off` option has been added to `--disk` to
|
||||
control disk space management: `sparse=on` (default) enables thin
|
||||
provisioning with space reclamation, while `sparse=off` provides thick
|
||||
provisioning with consistent I/O latency. (#7666)
|
||||
|
||||
### Notable Performance Improvements
|
||||
|
||||
* Transparent Huge Pages (THP) support has been extended to cover
|
||||
anonymous shared memory (`shared=on`) via `madvise`. Previously, THP
|
||||
was only used for non-shared memory. (#7646)
|
||||
* The `vhost-user-net` device now uses the default set of vhost-user
|
||||
virtio features, including `VIRTIO_F_RING_INDIRECT_DESC`, which
|
||||
provides a performance improvement. (#7653)
|
||||
|
||||
### MSHV Support Improvements
|
||||
|
||||
* Optimize CPU state update after emulation by only updating special
|
||||
registers when changed (#7603)
|
||||
* Enable SMT for guests with `threads_per_core > 1` (#7668)
|
||||
* Stub `save_data_tables()` to unblock VM pause/resume (#7692)
|
||||
* Handle `GHCB_INFO_SPECIAL_DBGPRINT` VMG exit in SEV-SNP guest exit
|
||||
handler (#7703)
|
||||
* Fix CVM boot failure on MSHV (#7548)
|
||||
* Fix CPU topology detection for multithreaded configurations (#7576)
|
||||
|
||||
### Notable Bug Fixes
|
||||
|
||||
* Fix VFIO device hot-remove leaving group and container file
|
||||
descriptors open, preventing re-add (#7676)
|
||||
* Fix snapshot restore when backing file is on read-only storage with
|
||||
`shared=false` (#7674)
|
||||
* Enforce `VIRTIO_BLK_F_RO` even if guest does not negotiate it
|
||||
(#7705)
|
||||
* Fix read-only block device FLUSH requests from OVMF preventing VMs
|
||||
from booting (#7706)
|
||||
* Fix vhost-user device not properly dropping unowned file descriptors
|
||||
(#7679)
|
||||
* Fix `vhost-user-block` `get_config` interoperability (#7617)
|
||||
* Fix vsock TOCTOU race condition by copying packet header from guest
|
||||
memory before processing (#7530)
|
||||
* Fix vsock handling of large TX packets spanning multiple data
|
||||
descriptors (#7680)
|
||||
* Add `gettid()` to all seccomp filters (#7596)
|
||||
* Fix MAC address parsing that wrongly allowed `+` instead of hex
|
||||
characters (#7579)
|
||||
* Improve UUID parse error message and `--net` fd help text (#7702)
|
||||
* Fix various inconsistencies in our OpenAPI specification file
|
||||
(#7716, #7726)
|
||||
* Various documentation fixes (#7602, #7606)
