[libvirt-users] Virsh Domain - Serial port; what does the attribute “port” of the serial node's child “target” do?

Hi all! I want to assign a real serialport to my kvm virtual machine via virsh. When I add the following XML snippet to the domain xml, it gets successfully attached but not as I expected it to happen. <serial type='dev'> <source path='/dev/ttyS3'/> <target type='isa-serial' port='2'> <model name='isa-serial'/> </target> <alias name='ua-Serial3'/> </serial> I expected, that given the target port 2 it will be connected to /dev/ttyS2 in the VM. But the target port gets totaly ignored and it will always be connected to ttyS0. Unless I define another serial before this, then it is connected to ttyS1, which is just the order of the serial devices in the xml then, still ignoring the target port. So, do I understand the target port absolutely wrong or is this a bug virsh? Cheers Thilo
