NAME
vdeq - Virtual Distributed Ethernet wrapper for QEMU virtual machines
SYNOPSIS
vdeq qemu ... qemu options ... -net vde[,vlan=n][,sock=socketpath] ...
other qemu options ...
vde{qemu_name} ... qemu options ... -net vde[,vlan=n][,sock=socket
path] ... other qemu options ...
vdeq qemu [ -sock socketpath [ ,socketpath [ ,... ] ] ] [ qemu_args ]
vde{qemu_name} [ -sock socketpath [ ,socketpath [ ,... ] ] ] [
qemu_args ]
DESCRIPTION
vdeq is a wrapper to start a QEMU virtual machine connected to a VDE
network. It uses the qemu -tun-fd parameter to set up the connection
with a vde_switch.
The command
vdeq qemu -b c -hda=sampledisk
starts a qemu machine which boots from the sampledisk image and has a
ne2000 ethernet interface connected to the standard vde_switch.
It is also possible to create symbolic links to the vdeq executable to
have a simpler command. If the link has a name that begins with vde the
remaning part of the name is taken as the qemu command. For example if
vdeq is linked to vdeqemu:
vdeqemu -b c -hda=sampledisk
starts qemu as above.
The new syntax is consistent with the new Qemu 0.8.0 network parame‐
ters. Using vdeq is possible to specify a vde interface in the same
way as user,tap or socket interfaces. The ’sock=’ parameter can be
used to use a specific socket. Please note that what qemu names as
vlan is not related to the 802.1q VLAN managed by the vde_switch. The
following command run a qemu VM with two ethernet interface connected
to the standard switch and to the switch with local socket
"/tmp/my.ctl" respectively
vde qemu -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net
vde,vlan=1,sock=/tmp/my.ctl
vdeqemu -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net
vde,vlan=1,sock=/tmp/my.ctl
The old syntax can be used with Qemu 0.8.0 but all the vde interfaces
are assigned to vlan 0.
vdeq qemu -sock /tmp/vde.ctl,/tmp/my.ctl -b c -hda=sampledisk
vdeqemu -sock /tmp/vde.ctl,/tmp/my.ctl -b c -hda=sampledisk
both start qemu with one ethernet interface connected both to the stan‐
dard switch and to the switch with local socket "/tmp/my.ctl".
OPTIONS
-sock socketpath, specify the UNIX socket to be used by local programs
for joining the VDE. The default value is "/tmp/vde.ctl" It is
also possible to indicate several socketpath (comma separated,
no blanks): in this case several interfaces are defined. The
first socketpath is connected to the first ne2k interface and so
on.
-h, -help, --help
print a Usage help.
NOTE
Qemu has changed its syntax for networking (cvs Nov.15 2005). As a
temporary solution use vdeoq and vdeoqemu instead of vdeq and vdeqemu
if you are running a qemu with the old syntax.
