Thanks a lot. Peter . BTW, one more question, recently sometimes we often hit another
issue that vm can’t boot from disk stuck in black screen show “Guest has not initialized
the display (yet).”
Our QEMU command line parameter like below.

Is it related with that QEMU vesion higher for libvirt?
Thanks

'netdev_add': Invalid parameter type for 'vhost', expected: boolean
Your qemu is too-new for libvirt. the 'netdev_add' command was converted
to a strict description by QMP schema and libvirt wasn't ready for that.

qemu: command: Generate -netdev command line via JSON->cmdline conversion
The 'netdev_add' command was recently formally described in qemu via the
QMP schema. This means that it also requires the arguments to be
properly formatted. Our current approach is to generate the command line
and then use qemuMonitorJSONKeywordStringToJSON to get the JSON
properties for the monitor. This will not work if we need to pass some
fields as numbers or booleans.
In this step we re-do internals of qemuBuildHostNetStr to format a JSON
object which is converted back via virQEMUBuildNetdevCommandlineFromJSON
to the equivalent command line. This will later allow fixing of the
monitor code to use the JSON object directly rather than rely on the
conversion.
v6.3.0-139-gb6738ffc9f
Thus you need at least libvirt 6.4.0 with that qemu.
