I see in libvirt you are supporting attach/detach devices to existing xml domain using <b>attachDeviceFlags
</b>and <b>detachDeviceFlags </b>APIs.</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
Now we are adding some qemu command to the xml domain <span style="background-color:rgb(255, 255, 255);display:inline !important">
related to some interfaces using alias names before</span> starting the VM, but we will face an issue with hot plug such devices, so I have two question here:</div>

<ol>
<li><span>Is it applicable to set the alias names for interfaces because I saw it's ignored when I add it to xml domain before starting the VM?</span></li><li><span>Is there a way or API to attach qemu commands to running domain as you are doing in attaching the device using <b style="text-align:start;background-color:rgb(255, 255, 255)">attachDeviceFlags?</b></span></li></ol>
