See http://migeel.sk/blog/2009/04/21/gdb-and-qemu-on-windows/ and http://qemu-forum.ipi.fi/viewtopic.php?f=5&t=5579&p=16248&hilit=gdb+ipv6#p16248 Seems like a very easy fix. Regards, Matthijs ter Woord There is an alternative way to force gdbserver to use ipv4 instead ipv6 without changing the source code. Use this command: c:\>qemu -S -gdb tcp::1234,ipv4 <...other parameters> Works for me until there is a bugfix for this. Thanks. I have a patch for this... Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
