(This question may be not quite acceptable for this list - I'm not sure whether
this is VDE or QEMU issue, and sorry for possible inconveniences).

I'm using QEMU 2.1.1 to emulate SPARC system and have vde network between two
VMs and host system, organized as shown:

         + +
         |                 |
         |                 |
         vm0               vm1
         eth0              eth0 ---

On host, I'm running vde_switch and extra stuff as:

vde_switch -tap tap0 -daemon -mod 660 -group [group]
ip addr add dev tap0
ip link set tap0 up
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s -o [external network iface] 

VMs are running with:

qemu-system-sparc -m 256 -net nic -net vde -hda vm0.img
qemu-system-sparc -m 256 -net nic -net vde -hda vm1.img

Everything looks good, but...

...the problem: I need to build redundant network by using the same method, i.e.
improve the network shown above with:

         + +
         |                 |
         |                 |
         vm0               vm1
         eth1              eth1 ---

I'm trying to run two vde switches:

vde_switch -sock /tmp/vde0 -tap tap0 -daemon -mod 660 -group [group]
vde_switch -sock /tmp/vde1 -tap tap1 -daemon -mod 660 -group [group]

and run VMs with:

qemu-system-sparc -m 256 -net nic,vlan=1 -net vde,sock=/tmp/vde0,vlan=1 -net 
nic,vlan=2 -net vde,sock=/tmp/vde1,vlan=2 -hda vm0.img

but the result is:

Warning: hub port hub2port0 has no peer
Warning: lan 2 with no nics
Warning: netdev hub2port0 has no peer
Warning: requested NIC (anonymous, model unspecified) was not created (not 
supported by this machine?)

Is it possible to build redundant network as described above?
