Hi Li Li,


There is no way to do that now, without manually editing the domain xml using virsh on the
KVM host.


However, there is an upcoming feature that will allow users (if allowed by admin) to pass
extra VM/hypervisor configuration such as the xml code you've shared in case of KVM VMs. This
feature may hopefully make its way into master soon (so in 4.12.0.0 in future). Dingane (the
author) can share more details on that.

Subject: How to use ehci usb controller on kvm?

Hello guys,

I need to transmit a USB3.0 device to guest VM.

The VM created by cloudstack uses the piix3-uhci controller, so it is impossible to identify
USB 2.0 or USB3.0 devices in the guest vm.

Is there any way to add EHCI controller to VM by default?


for example


<controller type='usb' index='0' model='piix3-uhci'>
<controller type='usb'index='1' model='ehci'/>
