# v0.11.0
|
||||
|
||||
This release has been tracked through the [0.11.0 project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/14).
|
||||
|
||||
Highlights for `cloud-hypervisor` version 0.11.0 include:
|
||||
|
||||
### `io_uring` support by default for `virtio-block`
|
||||
|
||||
Provided that the host OS supports it (Linux kernel 5.8+) then `io_uring` will
|
||||
be used for a significantly higher performance block device.
|
||||
|
||||
### Windows Guest Support
|
||||
|
||||
This is the first release where we officially support Windows running as a
|
||||
guest. Full details of how to setup the image and run Cloud Hypervisor with a
|
||||
Windows guest can be found in the dedicated [Windows
|
||||
documentation](docs/windows.md).
|
||||
|
||||
### `vhost-user` "Self Spawning" Deprecation
|
||||
|
||||
Automatically spawning a `vhost-user-net` or `vhost-user-block` backend is now
|
||||
deprecated. Users of this functionality will receive a warning and should make
|
||||
adjustments. The functionality will be removed in the next release.
|
||||
|
||||
### `virtio-mmmio` Removal
|
||||
|
||||
Support for using the `virtio-mmio` transport, rather than using PCI, has been
|
||||
removed. This has been to simplify the code and significantly
|
||||
reduce the testing burden of the project.
|
||||
|
||||
### Snapshot/Restore support for ARM64
|
||||
|
||||
When running on the ARM64 architecture snapshot and restore has now been
|
||||
implemented.
|
||||
|
||||
### Improved Linux Boot Time
|
||||
|
||||
The time to boot the Linux kernel has been significantly improved by the
|
||||
identifying some areas of delays around PCI bus probing, IOAPIC programming and
|
||||
MPTABLE issues. Full details can be seen in #1728.
|
||||
|
||||
### `SIGTERM/SIGINT` Interrupt Signal Handling
|
||||
|
||||
When the VMM process receives the `SIGTERM` or `SIGINT` signals then it will
|
||||
trigger the VMM process to cleanly deallocate resources before exiting. The
|
||||
guest VM will not be cleanly shutdown but the VMM process will clean up its
|
||||
resources.
|
||||
|
||||
### Default Log Level Changed
|
||||
|
||||
The default logging level was changed to include warnings which should make it
|
||||
easier to see potential issues. New [logging
|
||||
documentation](docs/logging) was also added.
|
||||
|
||||
### New `--balloon` Parameter Added
|
||||
|
||||
Control of the setup of `virtio-balloon` has been moved from `--memory` to its
|
||||
own dedicated parameter. This makes it easier to add more balloon specific
|
||||
controls without overloading `--memory`.
|
||||
|
||||
### Experimental `virtio-watchdog` Support
|
||||
|
||||
Support for using a new `virtio-watchdog` has been added which can be used to
|
||||
have the VMM reboot the guest if the guest userspace fails to ping the
|
||||
watchdog. This is enabled with `--watchdog` and requires kernel support.
|
||||
|
||||
### Notable Bug Fixes
|
||||
|
||||
* MTRR bit was missing from CPUID advertised to guest
|
||||
* "Return" key could not be used under `CMD.EXE` under Windows SAC (#1170)
|
||||
* CPU identification string is now exposed to the guest
|
||||
* `virtio-pmem` with`discard_writes=on` no longer marks the guest memory as
|
||||
read only so avoids excessive VM exits (#1795)
|
||||
* PCI device hotplug after an unplug was fixed (#1802)
|
||||
* When using the ACPI method to resize the guest memory the full reserved size
|
||||
can be used (#1803)
|
||||
* Snapshot and restore followed by a second snapshot and restore now works
|
||||
correctly
|
||||
* Snapshot and restore of VMs with more than 2GiB in one region now work
|
||||
correctly
|
||||

||||
