VDE is an ethernet compliant virtual network which includes tools such
|
|
as 'vde_switch' and 'vdeqemu'. VDE switch has several virtual ports
|
|
where virtual machines, applications, virtual interfaces and
|
|
connectivity tools can be virtually plugged in. VDE qemu works as a
|
|
wrapper for running qemu virtual machines that connects transparently
|
|
to a specified vde_switch
|
|
|
|
VDE is dependant upon TUN/TAP support in the Linux Kernel; this comes
|
|
enabled by default with Slackware 13's 'generic' kernel. To enable
|
|
TUN/TAP support manually, you must set the following entry in your
|
|
kernel's '.config' file and recompile:
|
|
CONFIG_TUN=m
|
|
|
|
## Experimental features
|
|
If you know/want vde2's experimental features, execute the script as:
|
|
EXPERIMENTAL=true sh vde2.SlackBuild
|
|
|
|
## Configuration
|
|
An init script has been provided in /etc/rc.d/rc.vde2 to use with
|
|
vde_switch. Edit this script and provide the TAP inteface name as
|
|
well as the subnet for your Virtual Switch to use. Do NOT choose
|
|
a subnet which is already in use. More than likely, the default
|
|
values will work fine.
|
|
|
|
## VDE + Qemu/kvm
|
|
A common usage for vde_switch is to be able to have emulated OS's
|
|
via Qemu behave as if they were actually attached to a Local Network.
|
|
To enable this functionality with Qemu, replace any calls to 'qemu'
|
|
with the following command:
|
|
|
|
vdeqemu -net vde,vlan=0 -net nic,vlan=0,macaddr=AA:BB:CC:DD:EE:FF
|
|
|
|
Note that the 'macaddr' string is optional but can prove to be
|
|
quite useful when used in conjuction with a DHCP server (such as
|
|
dhcpd or dnsmasq) to assign IP's based upon MAC address.
|
|
|
|
Do not forget to include the options which point vdeqemu to your
|
|
ISO image to boot along with any other options you may have used
|
|
with 'qemu' such as -localtime, -nographic etc.
|
|
|
|
## Startup
|
|
To have this start upon each boot, add the following lines to
|
|
/etc/rc.d/rc.local and make sure rc.vde2 is executable.
|
|
|
|
# Start vde_switch
|
|
if [ -x /etc/rc.d/rc.vde2 ]; then
|
|
/etc/rc.d/rc.vde2 start
|
|
fi
|
|
