How to Enable the Serial Console for virsh, centos
Posted: 20 Apr 2015 10:58
These are the steps I took to allow the serial console in efa build from scratch on Centos to work under kvm/qemu so I can access the server console at all times
Configure the Serial Terminal
vi /etc/init/ttyS0.conf
Allow root login via ttyS0
vi /etc/securetty
Start the serial console
initctl start ttyS0
Test the serial console via the host machine
virsh console <efa machine> <enter><enter>
Configure Boot Output to use the serial console as well
vi /etc/grub.conf
reboot and test
