@naseemvk are there any parameters you want changing that you cannot? this can be interpretted as two different featture requests. One specific for some missing knobs to turn and One generic to tweak any KVM based VM.

By design this isn't possible in CloudStack. However, you can use the extraconfig feature to pass specific xml you want to add to your domain, or use the Guest hooks feature to write a script/parser to create xml you'd like in your VM: https://github.com/apache/cloudstack/blob/main/agent/conf/agent.properties#L110
In addition to this, we also support qemu hooks feature (see https://libvirt.org/hooks.html#etc-libvirt-hooks-qemu )
