Description J. Bruce Fields 2010-11-23 15:57:42 EST
If I add a new drive to a running domain using the "add new hardware" button, on restarting the domain I get an error like

error: Failed to start domain rhel6
error: internal error Process exited while reading console log output: qemu-kvm: -drive file=/var/lib/libvirt/images/rhel6-1.img,if=none,id=drive-virtio-disk1,format=raw: Duplicate ID 'drive-virtio-disk1' for drive
qemu-kvm: -device virtio-blk-pci,bus=pci.0,addr=0x8,drive=drive-virtio-disk1,id=virtio-disk1: Duplicate ID 'virtio-disk1' for device

Investigation shows that the xml file does indeed contain duplicate entries:

$ cat /etc/libvirt/qemu/rhel6.xml
...
    <disk type='file' device='disk'>
      <driver name='qemu' type='raw'/>
      <source file='/var/lib/libvirt/images/rhel6-1.img'/>
      <target dev='vdb' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </disk>
    <disk type='file' device='disk'>
      <driver name='qemu' type='raw'/>
      <source file='/var/lib/libvirt/images/rhel6-1.img'/>
      <target dev='vdb' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
...

Removing one of them manually with a text editor and then restarting libvirtd resolves the problem.

This is 100% reproduceable.
