I'm gonna necro this. I'm on 3.2, and I have the same problem. I actually couldn't get Remix to boot, so I used vanilla Android-x86. It boots, but no mouse. I also tried ChromeOS images by ArnoldTheBat, but those wouldn't boot, either. I've had a lot of problems getting HVMs to work (probably PEBKAC, but that's why I've never been a huge fan of Xen). Any settings I can fiddle with?
