|
|
<ul>
|
|
<li><strong>New features</strong>
|
|
<ul>
|
|
<li>shmem: Add support for additional models<br/>
|
|
The shmem device can now utilize QEMU's ivshmem-plain and
|
|
ivshmem-doorbell, more modern versions of ivshmem
|
|
</li>
|
|
<li>vbox: Add VirtualBox 5.1 support
|
|
</li>
|
|
<li>libssh: New transport<br/>
|
|
The new libssh transport allows one to connect to a running
|
|
libvirtd via SSH, using the libssh library; for example:
|
|
<tt>qemu+libssh://<i>server</i>/system</tt>
|
|
</li>
|
|
<li>vhost-scsi: Add support scsi_host hostdev passthrough<br/>

|
|
volumes in qemu using the "gluster_debug_level" option in qemu.conf
|
|
</li>
|
|
<li>memory hotplug: Slot numbers for memory devices are now
|
|
automatically allocated and thus persistent. In addition slot numbers
|
|
can be specified without providing a base address, which simplifies
|
|
user configuration
|
|
</li>
|
|
<li>qemu: Express devices will be placed on PCIe bus by default<br/>
|
|
For machine types that use a PCI Express root bus
|
|
(e.g. x86_64/Q35 and aarch64/virt), any unaddressed PCI
|
|
device that is an Express device (all virtio-1.0 devices,
|
|
e1000e, nec-xhci, vfio assigned devices) will be placed on
|
|
an Express controller (i.e. a pcie-root-port) instead of a
|
|
legacy PCI controller (i.e. pci-bridge) with the root ports
|
|
added as needed
