@aron-ac , I think we will need more of a plan than just adding this kernel featureas an option. what would you think this would functionally look like? an agent property a switch in the host properties, ... etc.
I don´t want to discourage you, you are making a valid request but this is on a volunteer basis and I want to prevent your request from just sinking into memory/oblivian.

@DaanHoogland we made this work by writing a groovy script and we used it as a hook to set mq during vm creation. The script basically injected the mq config line into the libvirt XML. I would suggest as a feature we make this available as a checkbox in the UI during VM creation and part of data sources available in TF and the API etc.

@aron-ac I like your idea of a tick box. Would you mind sharing that groovy script?

[aron-ac]

@alexandremattioli if I was still at the company where we wrote it I would absolutely share. Fortunately/unfortunately I'm no longer there and no longer have access to that script.

We do not have any work in progress for this at the moment so moving it out of 4.19.0.0 milestone
