Cloud-Hypervisor 0.11 comes with some prominent improvements for this increasingly used component in the open-source Linux virtualization stack. As mentioned, even Microsoft has been working with Cloud-Hypervisor among other IHVs and ISVs.
With Cloud-Hypervisor 0.11 the highlights are:
- The existing IO_uring back-end is now enabled by default for VirtIO-Block. This default change allows for much better performance when running Cloud-Hypervisor 0.11 on Linux 5.8 or newer.
- Recently Intel engineers and others have been working on bits around Windows guest support while Cloud-Hypervisor 0.11 is the first release having officially supported Windows guest support.
- The AArch64/ARM64 code has snapshot/restore support now implemented.
- Faster boot time of the Linux kernel thanks to various optimizations.
- Experimental virtio-watchdog support.
- Many bug fixes.
This release has seen contributions from Microsoft, Google, and ARM, in addition to Intel.
