If yes, which transfer rates have you reached? USB keys (storage devices) were the primary target I used for testing. In fact, with EHCI I can run a linux guest from a USB key just fine - something I just verified again: qemu-kvm -usbdevice host:${USBDEV} where USBDEV is the vendor:product id from lsusb. Add other args to install from a CD/DVD to the USB key. If your mileage varies first and foremost make sure the VM is using kvm -- speed is horrible with qemu/tcg.
