Hello all!
I want to add a serial port to lguest as part of a bigger project.
Problem is I can't even launch it for the past three weeks.
i am using this cmd:
sudo ~/src/linux-2.6.32/Documentation/lguest/lguest 64
~/src/linux-2.6.32/vmlinux --tunnet=192.168.19.1
--block=/home/borod/lg/initrd-1.1-i386.img root=/dev/vda
