I can't find how does the diver name 'qemu' impact the process of building command line for qemu. So is it possible to remove the checking for driver name?
Otherwise, we should make 'qemu' become a valid driver name for virsh.

This is fixed upstream by 12a41822e14b558f7ffb4812978b957f3d228f23

A follow-up upstream patch dfec22cc6035a95ff1c7609ea060029cb99182cc is needed to deal with the issue more completely

Verify this bug with libvirt-0.8.2-7.el5 on RHEL5u6 Server x86_64 kvm, and PASSED.

Now libvirt allow user to specify driver name.

1. Start a guest.
2. Add a disk using virsh command:
# virsh attach-disk rhel5u5 /dev/VolGroup00/lvolhome vda --sourcetype block --driver qemu --subdriver raw 
Disk attached successfully
3. Check the new disk xml
    <disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/dev/VolGroup00/lvolhome'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>

The new disk works fine in guest.
4. Shut down the guest, and start it successfully.
# virsh start rhel5u5
Domain rhel5u5 started
