(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:
host
tap0
+ 192.168.100.254 +
| |
| |
vm0 vm1
eth0 eth0
192.168.100.1 --- 192.168.100.2
On host, I'm running vde_switch and extra stuff as:
vde_switch -tap tap0 -daemon -mod 660 -group [group]
ip addr add 192.168.100.254/24 dev tap0
ip link set tap0 up
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.100.0/24 -o [external network iface]
-j MASQUERADE
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:
host
tap1
+ 192.168.101.254 +
| |
| |
vm0 vm1
eth1 eth1
192.168.101.1 --- 192.168.101.2
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?
Thanks in advance,
Dmitry
