Setup virtual serial connection for Windows VMs FAILS

[Venkatesh Petla]

Hi,

To setup a virtual serial connections between two Windows 2008 R2(64-bit) guest VMs, I am referring the link
http://www.linux-kvm.org/page/WindowsGuestDrivers/UpdatedGuestDebugging

I started the host VM using the command
# /usr/local/bin/qemu-system-x86_64 -smp 1 -enable-kvm -m 512 -boot c -chardev stdio,id=mon0 -mon chardev=mon0 -serial tcp::4445,server,nowait -hda /mnt/sda5/var/lib/libvirt/images/win2008host.img

To start a target VM, the link specifies the below command
/usr/local/bin/qemu-system-x86_64 \--enable-kvm \-m 1024 \-drive file=win-target.img \-chardev stdio,id=mon0 \-mdev=mon0 \-serial tcp:127.0.0.1:4445.

I am using the QEMU emulator version 0.15.1 (qemu-kvm-0.15.1). The command is lil bit changed and also doesn't have -mdev option. I executed the below command.

# /usr/local/bin/qemu-system-x86_64 -enable-kvm -smp 1 -m 512 -boot c -chardev stdio,id=mon0 -mon chardev=mon0 -serial tcp:127.0.0.1:4455 -hda /var/lib/libvirt/images/win2008target.img

It through the error
inet_connect_opts: connect(ipv4,127.0.0.1,127.0.0.1,4455): Connection refused
chardev: opening backend "socket" failed: Connection refused
qemu: could not open serial device 'tcp:127.0.0.1:4455': Connection refused

Please let me know if any one knows how to fix issue.

Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
