Posted June 21, 2024 by Cloud Hypervisor Team ‐ 2 min read
This release has been tracked in our roadmap project as iteration v40.0. The following user visible changes have been made:
Support for Restoring File Descriptor Backed Network Devices
It is now possible to pass file descriptors over the HTTP API (and using
ch-remote) when restoring to update the file descriptors for network devices.
This enables snapshot & restore functionality for guests using macvtap or
other file descriptor backed network devices. (#6286)
Notable Bug Fixes
- Default values have been removed from required fields in the OpenAPI metadata (#6495)
- The help syntax of
ch-remote remove-devicehas been improved (#6456) - A double close of file descriptors has been fixed when using
--serial(#6486) - To prevent loops a limit on the nesting level for QCOW2 backing files has been introduced (#6482)
- Boot time performance has been improved with multiple cores by avoiding
cpuidinstructions and by seeding the in kernel file descriptor table (#6498, #6478) - L1 cache details are more likely to be propagated into the guest (#6523)
- The default topology for guests now uses multiple cores rather than sockets (#6504)
