Date: Mon, 10 Feb 2020 11:51:09 -0000

Public bug reported:

I start qemu version 4.2.50 in a first terminal :

$ sudo ./qemu-system-hppa -boot d -serial telnet::4441,server -drive
if=scsi,bus=0,index=6,file=./hpux.img,format=raw -serial mon:stdio -D
/tmp/foo -nographic -m 512 -d nochain -cdrom
./HPUX_9.05_Installation_Disc_S700.iso -D /tmp/foo -net nic,model=tulip
-net tap

qemu-system-hppa: -serial telnet::4441,server: info: QEMU waiting for
connection on: disconnected:telnet:0.0.0.0:4441,server

In another terminal, I launch "telnet localhost 4441"

And in the qemu window I have the following error:

Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:220:
qemu-system-hppa: Device 'serial0' is in use
