+ * virnetdevopenvswitch: Various improvements
+
+ The code that handles ``<interface type='vhostuser'/>`` was given various
+ improvements. So far, libvirt assumed vhostuser interfaces are handled

+ Now a guest can be started successfully even if the interface is created by
+ some other tool (e.g. ``dpdk-testpmd``). Also, the code that detects the
+ interface name was adopted to new versions of OpenVSwitch and thus can

And with sufficiently new guest agent + (5.3.0 or newer) the API also handles disks on CCW bus. +
+ * conf: Add support for keeping TPM emulator state +
Is this a new feature, maybe?
+ Currently, swtpm TPM state file is removed when a transient domain is + powered off or undefined. Add per-TPM emulator option ``persistent_sate``
Ouch, did we introduce another XML element using an underscore? s/sate/state/
