v31.0
This release has been tracked in our roadmap project as iteration
v31.0. The following user visible changes have been made:
Update to Latest acpi_tables
Adapted to the latest acpi_tables. There has been significant API changes in
the crate.
Update Reference Kernel to 6.2
Updated the recommended guest kernel version from 6.1.6 to 6.2.
Improvements on Console SIGWINCH
Handler
A separate thread had been created to capture the SIGWINCH
signal and resize
the guest console. Now the thread is skipped if the console is not resizable.
Two completely different code paths existed for handling console resizing, one
for tty
and the other for pty
. That makes the understanding of the console
handling code unnecessarily complicated. Now the code paths are unified. Both
tty
and pty
are supported in single SIGWINCH
handler. And the new handler
can works with kernel versions earlier than v5.5.
Remove Directory Support from MemoryZoneConfig::file
Setting a directory to MemoryZoneConfig::file
is no longer supported.
Before this change, user can set a directory to file
of the --memory-zone
option. In that case, a temporary file will be created as the backing file for
the mmap(2)
operation. This functionality has been unnecessary since we had
the native support for hugepages and allocating anonymous shared memory.
Documentation Improvements
- Various improvements in API document
- Improvements in Doc comments
- Updated Slack channel information in README
Notable Bug Fixes
- Fixed the offset setting while removing the entire mapping of
vhost-user
FS
client. - Fixed the
ShutdownVmm
andShutdown
commands to call the correct API
endpoint.

v30.0
This release has been tracked in our roadmap project as iteration
v30.0. The following user visible changes have been made:
Command Line Changes for Reduced Binary Size
The clap
crate was replaced by the argh
crate to create our command
line, which reduced our release binary size from 3.6MB to 3.3MB. There
were several syntax changes:
- All
--option=value
commands now are--option value
. - The
--disk DISK1 DISK2
command now is--disk DISK1 --disk DISK2
. - The
-vvv
command now is-v -v -v
Basic vfio-user Server Support
Our vfio-user
crate is extended to provide basic server side support
with an example of gpio vfio-user device. This crate now is moved to its
own repository under the
rust-vmm
organization.
Heap Profiling Support
A new building target is added for profiling purposes with examples of
heap profiling using dhat
gated by the dhat-heap
feature.
Documentation Improvements
The documentation on Intel TDX is expanded with details of the building
and using TD-Shim,
references to TDX Tools, and
version information of guest/host kernel/TDVF/TDShim being tested. Also,
a new 'heap profiling' documentation is added with improvements on the
existing 'profiling' documentation.
Notable Bug Fixes
- Close FDs for TAP devices that are provided to VM (#5199, #5206)
- Set vcpu thread status properly and signal
exit_evt
upon thread exit (#5211) - Populate CPUID leaf 0x4000_0010 (TSC frequency) (#5178, #5179)
- Inform the TPM guest driver upon failed TPM requests on the host (#5151)
- Bug fix to OpenAPI specification file (#5186)
