Communication between Qemu/KVM guest and host

Hi *,

I need to write text from my Qemu/KVM host machine to guest without using ssh.

I’ve launched kvm with the option:


-serial unix:/tmp/socket,server,nowait

after you can read/write data from host using unixterm (located in vde package or any other program to read/write serial console as socat or others).

From guest machine you can use cat /dev/ttyS0 to read data and echo “text” > /dev/ttyS0 to write on serial port.

Happy hacking.
