#417 network problems
hi,
some problems with network...
1) with socket
modprobe kvm
modprobe kvm-intel
$ kvm -hda mydisk -m 192 -localtime -k fr -net nic -net socket,listen=:1234
KO segmentation fault with option "-net nic -net socket,listen=:1234"
OK with user or tap nic, no problem
KO same problem with qemu
KO same problem with -no-kvm option
2) with vde switch
modprobe kvm
modprobe kvm-intel
modprobe tun
tunctl -u toto
ifconfig tap0 172.20.0.1 netmask 255.255.255.0 up
$ vde_switch -s /tmp/switch -daemon
$ vde_plug2tap -s /tmp/switch -daemon tap0
$ vdekvm -hda mydisk -net nic -net vde,sock=/tmp/switch
KO "arg ,sock=/tmp/switch TUNGETIFF ioctl() failed: Invalid argument"
starts but without connected to the virtual switch
KO "samsung kernel: kvm: 6245: cpu0 unhandled wrmsr: 0xc0010117 data
0" in /var/log/everything.log
OK with vdeqemu

Hi,
Gerardo Exequiel Pozzi find the net socket problem: see http://bugs.archlinux.org/task/13754
Note that vde works if you just use the native vde support, i.e., make sure vde support is compiled in that vdeplug library is available and just drop the vdeq/vdeqemu/vdekvm and keep the -net vde,... part.
