Re: Console of P2V?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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'/>
      <alias name='serial0'/>
    <console type='pty' tty='/dev/pts/0'>
      <source path='/dev/pts/0'/>
      <target type='serial' port='0'/>
      <alias name='serial0'/>

at that point I just type in "virsh console $DOM" in the command line

# virsh console XXXX
Connected to domain XXXX
Escape character is ^]

XXXX4 login:

I often have to hit the enter key a once or twice to get the login prompt once connected.

I generally use

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?

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

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!
