When I use it like that, my start command was :
# kvm -k fr -localtime -m 384 -usb -net nic,macaddr=52:54:00:12:34:59 -net tap -hda vmubuntu.img
And then, I use virtio drivers for paravirtualization :
# kvm -k fr -localtime -m 384 -net nic,macaddr=00:16:3e:35:6a:54,model=virtio -net tap -drive file=vmdebian.img,if=virtio
Now, I use virt-manager to create and launch my VMs.
I have to tell also that I use a bridge interface, as my main network
interface :
# ifconfig

# brctl show

br0 8000.00301b4305c6 no eth0

The tap interface is added to my bridge when I start a VM.
Certainly due to that script :
$ cat /etc/kvm/kvm-ifup
#!/bin/sh
switch=$(ip route ls | awk '/^default / { for(i=0;i<NF;i++) { if ($(i)
== "dev") print $(i+1) }}'| head -n 1)
/sbin/ifconfig $1 0.0.0.0 up
/usr/sbin/brctl addif ${switch} $1
exit 0
It is quite similar with the qemu one :
$ cat /etc/qemu-ifup
#!/bin/sh
#sudo -p "Password for $0:" /sbin/ifconfig $1 172.20.0.1
/sbin/ifconfig $1 up
/usr/sbin/brctl addif br0 $1

Normal, Kvm, th command is based on qemu, adding support of full virtualisation for Intel VT and AMD SVM.
Kvm, the command, will certainly end in qemu.
