Subject: [Qemu-devel] Multiple Nics on a VLAN
Date: Tue, 10 Nov 2009 17:16:12 -0800	[thread overview]
Message-ID: <3540a3280911101716o6a002149ld7b0644a362969a8@mail.gmail.com> (raw)

Hi All,
I'm using the following command to have two nics in multicast on the
same vlan. I see a storm of ARP requests. Does any one have any
suggestions?

qemu.bin.kvm84 -hda /live_disks/clone-disk.img -snapshot -serial
telnet:SERVER:50000,nowait,server -monitor
tcp:SERVER:51000,server,nowait,nodelay -p 61000 -m 768m -smp 1 -vnc
SERVER:10 -net nic,model=e1000,vlan=0,macaddr=56:48:AA:BB:CC:DD -net
tap,vlan=0,script=netscripts/net0-ifup -net
nic,model=e1000,vlan=1,macaddr=56:48:AA:BB:CC:EE -net
socket,vlan=1,mcast=230.0.0.1:3001 -net
nic,model=e1000,vlan=1,macaddr=56:48:AA:BB:CC:FF -net
socket,vlan=1,mcast=230.0.0.1:3001 --uuid
cc6145a8-cdae-11de-ac18-003048d4fd3e

However, If I launch two QEMU with one nic in multicast, where eth0 in
both QEMU are connected to vlan1, the I can ping 1.1.1.1 -> 1.1.1.2
and vice versa.

I'm running CENTOS inside the VM.

Thanks,
Shesha
