Exactly as original post, if I place -serial telnet::4441,server ahead of -serial mon,stdio on the command line, it dumps core and aborts. if I flip them, it runs... BUT! The vm console output appears in the terminal where I launched qemu, I get no output in the telnet session. That's backwards. I have no access to the qemu console and can't issue commands to do things like change the CDROM. full command startup script (this one works but output doesn't happen where I expect) #!/bin/sh CDROM="-cdrom HP-UX-OE-1.iso" QEMU=/home/ascott/Documents/hpux/qemu/qemu/build/qemu-system-hppa IMAGE=/home/ascott/Documents/hpux/hpux.img $QEMU -boot d -serial mon:stdio -serial telnet::4441,server -drive if=scsi,bus=0,index=6,file=$IMAGE,format=raw -nographic -m 512 -d nochain $CDROM -net nic,model=tulip -net user This one dumps core with the serial0 error from the originla post: #!/bin/sh CDROM="-cdrom HP-UX-OE-1.iso" QEMU=/home/ascott/Documents/hpux/qemu/qemu/build/qemu-system-hppa IMAGE=/home/ascott/Documents/hpux/hpux.img $QEMU -boot d -serial telnet::4441,server -serial mon:stdio -drive if=scsi,bus=0,index=6,file=$IMAGE,format=raw -nographic -m 512 -d nochain $CDROM -net nic,model=tulip -net user ascott@vmhost01:~/Documents/hpux$ sh ./install-hpux.sh qemu-system-hppa: -serial telnet::4441,server: info: QEMU waiting for connection on: disconnected:telnet:0.0.0.0:4441,server=on Unexpected error in qemu_chr_fe_init() at ../chardev/char-fe.c:220: qemu-system-hppa: Device 'serial0' is in use Aborted (core dumped) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1862619 Title: "-serial telnet::xxxx,server" causes "Device 'serial0' is in use" Status in QEMU: Fix Released Bug description: 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 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1862619/+subscriptions
