Hi! I have installed successfully proxmox 2.0 in my server. It has four network cards:
vmbr0 -> eth0 physical network card bridge
vmbr1 -> eth1 physical network card bridge
vmbr2 -> eth2 physical network card bridge
vmbr3 -> eth3 physical network card bridge


root@virtual1:~# brctl show
bridge name bridge id STP enabled interfaces
vmbr0 8000.3c4a927c4db8 yes eth0 ------------> connected
tap100i0
veth101.0
vmbr1 8000.3c4a927c4db9 yes eth1--------------> connected
tap102i0
vmbr2 8000.002655ea3d48 yes eth2--------------> cable not connected, no link
tap100i1
tap102i1
vmbr3 8000.002655ea3d49 yes eth3---------------> cable not connected, no link
tap100i2
tap102i2

If I throw a ping from another network host, and I do a tcpdump error will look better.


Ping to 10.116.10.15(vmbr1) :


root@virtual1:~# tcpdump -i vmbr1 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vmbr1, link-type EN10MB (Ethernet), capture size 65535 bytes


10:08:41.539019 IP 10.116.30.1 > 10.116.10.15: ICMP echo request, id 1, seq 1027, length 40
10:08:41.539057 IP 10.116.10.15 > 10.116.30.1: ICMP echo reply, id 1, seq 1027, length 40


And now, ping to 10.116.10.26(vmbr2) other physical network card in theory:


root@virtual1:~# tcpdump -i vmbr2 icmp ----->>> Not show anything


But in vmbr1 yes...


root@virtual1:~# tcpdump -i vmbr1 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vmbr1, link-type EN10MB (Ethernet), capture size 65535 bytes


10:11:48.307929 IP 10.116.30.1 > 10.116.10.26: ICMP echo request, id 1, seq 1058, length 40
10:11:48.307961 IP 10.116.10.26 > 10.116.30.1: ICMP echo reply, id 1, seq 1058, length 40




And now, ping to 10.116.10.27(vmbr3) other physical network card in theroy:


root@virtual1:~# tcpdump -i vmbr3 icmp ----->>> Not show anything


But in vmbr1 yes...


root@virtual1:~# tcpdump -i vmbr1 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vmbr1, link-type EN10MB (Ethernet), capture size 65535 bytes
10:14:49.928829 IP 10.116.30.1 > 10.116.10.27: ICMP echo request, id 1, seq 1066, length 40
10:14:49.928864 IP 10.116.10.27 > 10.116.30.1: ICMP echo reply, id 1, seq 1066, length 40


I understand nothing, but the association Proxmox bad physical network card with bridge. The pings to 10.116.10.26 and 10.116.10.27 will must not operate but no link network card...


I think this a bug problem....Can I help me please?? Sorry for my english, thanks un advanced.
