When defining a VM with an emulated smartcard as specified at http://libvirt.org/formatdomain.html#elementsSmartcard, the VM won't start and issues the following error:

Using:
qemu-kvm-1.2.2-4.fc18.x86_64
libvirt-0.10.2.2-3.fc18.x86_64
virt-manager-0.9.4-4.fc18.noarch
kernel3.7.4-204.fc18.x86_64

In http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=blob;f=hw/ccid-card-emulated.c;h=f4a6da4283a3a27eaff154be7ad6ca75dee900d5;hb=HEAD#l25 (for roughly the version I'm using) it states that the parameter "db" should be used.

I'm not sure whether this is the issue, but db != database.  http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=blob;f=hw/ccid-card-emulated.c;h=f4a6da4283a3a27eaff154be7ad6ca75dee900d5;hb=HEAD#l118

Any help would be appreciated.  Thanks.
