[Qemu-discuss] Empty window since qemu 1.6.x

[Hermann J Beckers]

Since version 1.6.x I get an empty QEMU window, whenever I start a VM 
(also tested with 1.7.0) and qemu-system-x86-64 uses up to 90 % cpu 
time. OS is openSUSE 12.3 and 13.1 (no difference).

qemu 1.5 works with the (same) parameters:

/usr/local/bin/qemu-system-x86_64 -m 2048 -enable-kvm -monitor stdio 
-vga std \
   -net nic,model=e1000,name=nam$1,vlan=$1,macaddr=52:54:5$1:12:34:56 \
                -net tap,vlan=$1,name=nam$1  $2

$1 is a number between 1 and 9 to differentiate multiple qemu instances, 
$2 is mostly empty. It makes no difference if I change the -vga or the 
-monitor parameter.

Any hints?
