QEMU Command Line form not saved - no effect

[Espressomatic]

I'm running 7 beta 2, so I don't know if this is a new issue.

 

I'm trying to add a couple of command-line arguments to QEMU for a particular VM in the text box in the VM edit UI:

 

 

 

After updating/saving and then coming back to edit, the arguments are gone, like this:

 

 

If I display the inline XML (new feature), there's no XML displayed for this section - and going full XML view I can't find where these arguments should be inserted.

 

Can anyone validate this with Unraid 6.x?

You need to use libvirt xml format i.e.

 

<qemu:commandline> <qemu:arg value='-vga'/> <qemu:arg value='vmware'/> </qemu:commandline>

Thanks for the heads up!

 

Kind of thought the UI would create the XML based on what I typed into that box - sort of like every other form element on the page.

 

If the box were pre-populated with

 

<qemu:commandline>

</qemu:commandline>
 

 

then it would be instantly obvious what needed to be done.

Still can't get it to work. 

I'm in a hurry, about to head out the door, but the whole format (according to that link) seems completely obnoxious. Mainly because of the butchered XML - and the fact they're not using a nice structure of keys and values.

 

Ugh... Ugly. But here's what I'd been trying to do, finally working:

 

<qemu:commandline>
    <qemu:arg value='-boot'/>
    <qemu:arg value='menu=on,splash-time=5000'/>
  </qemu:commandline>

The amount of variables would be to large. Libvirt drop support for a similar process.

 

Unfortunately support for the domxml-from-native command has been removed from recentish libvirt, because we found that in practice it was too unreliable and incomplete to be useful.

 

There are two options other is qemu:override I will review help text.
