[Qemu-devel] qemu monitor/serial parameter change or bug in git head?

[Dennis Luehring]

qemu-system-alpha -m 1GB -nographic -monitor telnet::4440,server,nowait 
-serial telnet::3000,server -kernel clfskernel-4.2.3 -append 
'console=ttyS0' -initrd initramfs.cpio

using: git clone -b "v2.4.0.1" git://git.qemu-project.org/qemu.git and build

i see the normal
"QEMU waiting for connection on: disconnected:telnet::3000,server"
and connecting with telnet localhost 3000 shows kernel output

using: git clone git://git.qemu-project.org/qemu.git and build
git rev-parse HEAD
bc79082e4cd12c1241fa03b0abceacf45f537740

i get this
"qemu-system-alpha: -monitor telnet::4440,server,nowait: address 
resolution failed for :: Name or service not known"
and can't connect with telnet

is there a parameter/confguration change or is it a bug?
