Hi ......
I'm trying to configure my Solaris servers with only one NIC card to have 2 IP addresses as well as 2 different default gateways.
( NOT to be confused with multi-pathing - with 2 physical IPs & 1 virtual ip)
Thanks,

VDEQ(1) General Commands Manual VDEQ(1)
NAME
vdeq - Virtual Distributed Ethernet wrapper for QEMU/KVM virtual machines
SYNOPSIS
vdeq qemu [ --mod octalmode ] QEMU_OPTIONS -net vde[,vlan=n][,sock=socketpath][,port=n] QEMU_OPTIONS
vdeq kvm [ --mod octalmode ] KVM_OPTIONS -net vde[,vlan=n][,sock=socketpath][,port=n] KVM_OPTIONS
vde{qemu_name} [ --mod octalmode ] QEMU_OPTIONS -net vde[,vlan=n][,sock=socketpath][,port=n] QEMU_OPTIONS
OLD SYNOPSIS
vdeq qemu [ --mod octalmode ] [ -sock socketpath [ ,socketpath [ ,... ] ] ] [ qemu_args ]
vde{qemu_name} [ -sock socketpath [ ,socketpath [ ,... ] ] ] [ qemu_args ]
DESCRIPTION
vdeq is a wrapper to start a QEMU/KVM virtual machine connected to a VDE network. It uses the qemu/kvm -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. The
command
vdeq kvm -b c -hda=sampledisk
starts a kvm 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 remaining 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. If vdeq is linked to vdekvm:
vdekvm -b c -hda=sampledisk
starts kvm with the same parameters.
The new syntax is consistent with the new Qemu 0.8.0 network parameters. 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. port= can be used to specify the port of the switch, otherwise the first allo-
catable port is assigned. 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", port 10, respectively
vde qemu -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net vde,vlan=1,sock=/tmp/my.ctl,port=10
vdeqemu -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net vde,vlan=1,sock=/tmp/my.ctl,port=10
The following command run a kvm VM with two ethernet interface connected to the standard switch and to the switch with local socket
"/tmp/my.ctl", port 10, respectively
vde kvm -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net vde,vlan=1,sock=/tmp/my.ctl,port=10
vdekvm -net nic,vlan=0 -net nic,vlan=1 -net vde,vlan=0 -net vde,vlan=1,sock=/tmp/my.ctl,port=10
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 standard switch and to the switch with local socket "/tmp/my.ctl".
OPTIONS
--mod octalmode, specify the mode for comm socket.
-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.
By default qemu uses the same MAC address for every virtual machine, so if you plan to use several instances of qemu be sure to explicitly
set a different MAC address for each virtual machine. While generating your address beware to not use broadcast/multicast reserved MACs,
ethernet rules say: the multicast bit is the low-order bit of the first byte, which is "the first bit on the wire". For example
34:12:de:ad:be:ef is an unicast address, 35:12:de:ad:be:ef is a multicast address (see ETHERNET MULTICAST ADDRESSES section in
http://www.iana.org/assignments/ethernet-numbers for more informations).
