Title:
  Failed to create COM port in Windows Guest VM

Status in QEMU:
  Expired

Bug description:
  Hi,

  Tried to establish virtual serial connection between two Windows Guest
  VMs(Windows 2008 Server).

  As it mentioned under the link,
  http://www.linux-kvm.org/page/WindowsGuestDrivers/UpdatedGuestDebugging

  Started VM using the below command with serial device as TCP port.
  # qemu-system-x86_64 -smp 1 -enable-kvm -m 512 -boot c -serial 
tcp:127.0.0.1:50001,server,nowait -hda 
/mnt/sda5/var/lib/libvirt/images/win2008host.img

  And started WinDbg in the Windows VM, with serial port:COM1 and
  Baudrate:115200.

  It throws the error "Could not start kernel debugging using
  com:port:COM1,baudrate:115200 parameters, Win32 error 0n2. The system
  cannot find the file specified."

  Checked under Device Manager and there is no COM1 port.
  Does the -serial tcp:127.0.0.01:50001 creates COM1 port? I doubt.
  If no what are the parameters I should pass to WinDbg for serial port?

  Please help me how to solve this issue.

  Thanks
  Venkatesh
