    well
      libvirt has to know about the serial port and attach it to the
      console.
      

      do you have something like this in your XML file?
      

        <serial type='pty'>
        

              <source path='/dev/pts/0'/>
        

              <target type='isa-serial' port='0'>
        

                <model name='isa-serial'/>
        

              </target>
        

              <alias name='serial0'/>
        

            </serial>
      

          <console type='pty' tty='/dev/pts/0'>
      

            <source path='/dev/pts/0'/>
      

            <target type='serial' port='0'/>
      

            <alias name='serial0'/>
      

          </console>
      

    no, I have:

    
        <serial type='pty'>

          <target type='isa-serial' port='0'>

            <model name='isa-serial'/>

          </target>

        </serial>

        <console type='pty'>

          <target type='serial' port='0'/>

        </console>

    
    I can edit this with virsh edit [domain] but the get the
    same results as before. 

    When I look into the file thereafter, all edits are gone even though
    I got a success message with the editing

        I generally use
          

          GRUB_CMDLINE_LINUX_DEFAULT="console=tty0
          console=ttyS0,115200n8"
          

          and redo grub.cfg (i.e. update-grub, grub2-mkconfig)
          

        thanks for the pointer.
        

        I literally ran in the guests commandline
        

             GRUB_CMDLINE_LINUX_DEFAULT="console=tty0
        console=ttyS0,115200n8"
        

             sudo update-grub
        

        which did change anything to the behavior on the hosts cli
        

            Connected to domain '[domain]'
        

            Escape character is ^] (Ctrl + ])
        

        and then nothing
        

        so ... what is the error I am making?

              ... apologies if this isn't quite the right list, I tried
              to get the
              

              right one.
              

              But, my problem: I'm firing up a Centos 6.5 box > with
              virt-install,
              

              [...] and
              

              it boots fine, etc., etc., but I can't get to the console
              except
              

              through vnc;
              

              "virsh console" just shows a blank screen.
              

              1. I think this is absolutely the right list for your
              issue
              

            Yay. :-)
            

            2. is it really blank? or something
              like
              

                  Connected to domain '[domain]'
              

                  Escape character is ^] (Ctrl + ])
              

            Okay, it *does* say those things -- but that's all it says.
            <CR> gets
            

            me nowhere, as opposed to the other KVM hosts we have
            running.
            

            3. If I am not mistaken the guest
              needs to be configured in a
              

              certain way for
              

              virsh console [domain] to work. I can't say how though
              

            Hmmm... well, if anyone knows, I'm all ears.
            

            Thanks for the reply!
