</span>You should first come up with something that works when you try it<br>
manually, then try adapting that to the hook's syntax.<br>

</span>I guess you refer above to libvirt xml. This isn't strictly<br>
related to qemu, although in practice most usage of libvirt<br>
is with qemu.<br>
<span class="gmail-"><br>
><br>
> How do I write this in custom properties for qemu_cmdline?<br>
<br>
</span>If you have a working libvirt vm, with the options you need,<br>
simply check how it translated your xml to qemu's command line.<br>
You can see this either in its logs, or using ps.<br>
<br>
