SYS: Access a virtual machine’s console.

Share this link

To access the virtual machine’s console under X-Window, type:

# virt-manager

If you aren’t under X-Window, there is another way to access a virtual machine’s console: you have to create a serial console.

On the virtual machine, add the following line at the end of the /etc/inittab file:

# echo "S0:12345:respawn:/sbin/agetty ttyS0 115200" >>/etc/inittab

Add ‘console=ttyS0‘ at the end of the kernel lines in the /boot/grub/grub.conf file:

# grubby --update-kernel=ALL --args="console=ttyS0"

Allow root to connect at the console:

# echo "ttyS0" >>/etc/securetty

Now, reboot the virtual machine:

# reboot

Connect to the virtual machine’s console (here vm.example.com):

# virsh console vm.example.com
