Also on quickly connecting to the ports via the netcat tool (hoping that it
would make qemu to change its state from disconnected)
I see the following error "Error in getpeername: Transport endpoint is not
connected"
address@hidden:~/$ qemu-system-x86_64 --enable-kvm -hda Sisk.qcow2 -serial
telnet::0,server,nowait -serial telnet::0,server,nowait -nographic
QEMU 2.5.0 monitor - type 'help' for more information
(qemu) info chardev
parallel0: filename=null
serial1: filename=disconnected:telnet::0,server
serial0: filename=disconnected:telnet::0,server
compat_monitor0: filename=stdio
(qemu)
# COnnect quickly to the serial ports via netcat
address@hidden:~/$ netstat -tupan 2>/dev/null | grep "LISTEN.* $(pgrep -f
qemu)/qemu" | cut -d: -f2 | cut -d' ' -f1

address@hidden:~/$ ports=$(netstat -tupan 2>/dev/null | grep "LISTEN.* $(pgrep

address@hidden:~/$ for p in $ports; do echo | nc -w0 kvm $p >/dev/null; done
# Check the port status again. We see the the error "Error in getpeername:
