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

hi William
I generally use
GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8" and redo grub.cfg (i.e. update-grub, grub2-mkconfig)

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?

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!
