# v19.0
|
||||
|
||||
This release has been tracked through the [v19.0
|
||||
project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/22).
|
||||
|
||||
### Improved PTY handling for serial and `virtio-console`
|
||||
|
||||
The PTY support for serial has been enhanced with improved buffering when the
|
||||
the PTY is not yet connected to. Using `virtio-console` with PTY now results in
|
||||
the console being resized if the PTY window is also resized.
|
||||
|
||||
### PCI boot time optimisations
|
||||
|
||||
Multiple optimisations have been made to the PCI handling resulting in
|
||||
significant improvements in the boot time of the guest.
|
||||
|
||||
### Improved TDX support
|
||||
|
||||
When using the latest TDVF firmware the ACPI tables created by the VMM are now
|
||||
exposed via the firmware to the guest.
|
||||
|
||||
### Live migration enhancements
|
||||
|
||||
Live migration support has been enhanced to support migration with `virtio-mem`
|
||||
based memory hotplug and the `virtio-balloon` device now supports live
|
||||
migration.
|
||||
|
||||
### `virtio-mem` support with `vfio-user`
|
||||
|
||||
The use of `vfio-user` userspaces devices can now be used in conjunction with
|
||||
`virtio-mem` based memory hotplug and unplug.
|
||||
|
||||
### AArch64 for `virtio-iommu`
|
||||
|
||||
A paravirtualised IOMMU can now be used on the AArch64 platform.
|
||||
|
||||
### Notable bug fixes
|
||||
|
||||
* ACPI hotplugged memory is correctly restored after a live migration or
|
||||
snapshot/restore (#3165)
|
||||
* Multiple devices from the same IOMMU group can be passed through via VFIO
|
||||
(#3078 #3113)
|
||||
* Live migration with large blocks of memory was buggy due to an in issue in
|
||||
the underlying crate (#3157)
|
||||
|
||||
