Hi all,
I have a strange problem with my bridges configuration. I have a
rhel5.4 host with kvm-83-105 package installed. This host has two
bridged interfaces defined to use with kvm guests:
DEVICE=prodif
ONBOOT=yes
TYPE=Bridge
IPADDR=172.26.50.14
NETMASK=255.255.255.240
DELAY=0
STP=off
and
DEVICE=iscsif
ONBOOT=yes
TYPE=Bridge
DELAY=0
STP=off
I have installed two kvm guests (rhel5.4 also) with two virtual
interfaces using virtio driver on one guest and e1000 driver on the
other guest.
My problem is: when I do a ping between these guests over prodif bridge
all works as expected: ping responds. But if I do another ping over
iscsif bridge doesn't works. The only difference between prodif bridge
and iscsif bridge is that prodif has an IP address.
More info:
a) brctl show on host:
bridge name bridge id STP enabled interfaces
iscsif 8000.c201b3289830 no vnet3
vnet1
prodif 8000.226af089f4c3 no vnet2
vnet0
b) sysctl.conf on host:
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
I don't have iptables rules defined and net.ipv4.ip_forward is disabled
(but if I put sysctl -w net.ipv4.ip_forward=1, result is the same).
What am I doing wrong??
Many thanks.
I find the problem: mac address used on kvm guests. I have chegend to
00:XX:XX:XX:XX:XX.
