Sounds like virt-manager. qemu logs should be at /var/log/libvirt/qemu/$guest.log then. Any error messages in there? Any messages in the host kernel log (about usb device reset maybe?) Do you use an usb 2 controller? If not, can try whenever that improves things? Can be switched when you pick the "controller usb" in the virt-manager "devices ui". cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
