Have been trying to get a 64-bit Win7 guest to access a usb thumbdrive (and eventually an Apple iTouch). Host is CentOS 6.2 and the guest is running under qemu-kvm with SELinux enabled and sVirt separating guests from each other and guests from the host.

Do I need to install the virt-io drivers in the Win7 guest, or are there more permission and SELinux blocks in my path?
