[libvirt] [libvirt 0.6.4] Unable to set /domain/devices/serial[@port=1] as console?

When I do a "virsh define" with the following: <serial type='file'> <source path='/path/to/serial.log'/> <target port='0'/> </serial> <serial type='pty'> <target port='1'/> </serial> <console type='pty'> <target port='1'/> </console> The result is this: <serial type='file'> <source path='/path/to/serial.log'/> <target port='0'/> </serial> <serial type='pty'> <target port='1'/> </serial> <console type='file'> <source path='/path/to/serial.log'/> <target port='0'/> </console> ...a markedly different configuration. Is this the result of a bug, or a known behavior I've failed to catch in the docs? Thanks!
