The following is the commands to create a virtual bridge and virtual interfaces so you can use it with kvm\/qemu tap networking, Actually i think you can do all of this using a GUI interface via Virtual Machine Manager (virt-manager), but i don’t know why i feel its difficult to use it, anyway.<\/p>\n
You will need a tun enabled kernel, also tunctl and bridge-utils packages are installed in your system, in Fedora 12 i used yum to install them:<\/p>\n
yum install bridge-utils.`uname -m` tunctl.`uname -m` -y<\/p><\/blockquote>\n
For tun support in your kernel, you can modprobe tun and see the result, or checking the config file under \/boot\/ for CONFIG_TUN, for example in fedora:<\/p>\n
[root@shaker-testing ~]# egrep ‘^CONFIG_TUN’ \/boot\/config-2.6.31.9-174.fc12.x86_64
\nCONFIG_TUN=m<\/p><\/blockquote>\nanyway you do it, just make sure exist and probed (lsmod | grep tun)<\/p>\n
Finally here is the commands to create the virtual interface and virtual switch:<\/p>\n
[root@shaker-testing ~]# tunctl -b -u root -t tap0
\ntap0
\n[root@shaker-testing ~]# brctl addbr testing-br
\n[root@shaker-testing ~]# brctl addif testing-br tap0
\n[root@shaker-testing ~]# brctl addif testing-br eth0
\n[root@shaker-testing ~]# ifconfig tap0 0.0.0.0 promisc up
\n[root@shaker-testing ~]# ifconfig eth0 0.0.0.0 promisc up
\n[root@shaker-testing ~]# ifconfig testing-br 192.168.0.1 netmask 255.255.255.0
\n[root@shaker-testing ~]# brctl show
\nbridge name\u00a0\u00a0 \u00a0bridge id\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0STP enabled\u00a0\u00a0 \u00a0interfaces
\ntesting-br \u00a0 \u00a0\u00a0\u00a0\u00a0 8000.0019d13401c0\u00a0\u00a0 \u00a0no\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0eth0
\ntap0<\/p><\/blockquote>\nthats all, btw, 192.168.0.1 was my eth0\u00a0 IP Address, you have to give it to your virtual bridge.<\/p>\n
now run your machine, i usually run it as followes:<\/p>\n
qemu -hda \/storage\/testing1.img -m 256 -net nic,macaddr=00:1d:92:ab:3f:80 -net tap,ifname=tap0,script=no -alt-grab -vga std -name Testing1 -boot c -vnc :0<\/p><\/blockquote>\n
and then i login to it using vncviewer (i used -vnc :0 in the options) to configure its IP Address.. for example, if you are connecting\/using it in localhost then i use:<\/p>\n
vncviewer localhost:5900<\/p><\/blockquote>\n
or you can delete ‘-vnc:0’ so you don’t use vnc at all..<\/p>\n
