Hi there
I've set up a RHEL5.7 server [172.16.1.197] and created a RHEL5.7 KVM [172.16.1.200].
Its possible for the KVM [.200] to ping any server on the network:
Code:
[root@172.16.1.200 ~]# ping 172.16.1.123
PING 172.16.1.123 56(84) bytes of data
64 bytes from 172.16.1.123 icmp_seq=1 ttl=64 time=1.01 ms
but whenever i try and ping .200 from any other server [even on the host machine ~ .197] i get the following:
Quote:
[from 172.16.1.197] ping 172.16.1.200
PING 172.16.1.200 (172.16.1.200) 56(84) bytes of data.
From 172.16.1.197 icmp_seq=2 Destination Host Unreachable
From 172.16.1.197 icmp_seq=3 Destination Host Unreachable

i have configured the host and guest as per the following link:
Here
Here is the 'virsh edit <KVMHOSTNAME>
Code:
<interface type='bridge'>
<mac address= {MAC ADDRESS)/>
<source bridge='br0'/>
<model type='virtio'/>
</interface>
Host server:
Code:
[root@172.16.1.197~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.782bcb44012b no vnet0
eth0
virbr0 8000.000000000000 yes
changes in /etc/sysctl.conf
Code:
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
contents of ifcfg-eth0 [on host]
Code:
[root@172.16.1.197network-scripts]# vi ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
HWADDR={MAC ADDRESS}
ONBOOT=yes
BRIDGE=br0
NM_CONTROLLED=no
contents of ifcfg-br0 [on host]
Code:
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
HWADDR={MAC ADDRESS}
IPADDR=172.16.1.197
NETMASK=255.255.255.0
GATEWAY=172.16.1.1
ONBOOT=yes
DELAY=0
NM_CONTROLLED=no
EDIT: i have switched off iptables on both host and guest system, still cannot reach the system.
I don't understand why other servers cant see the .200 at this point. any help will be greatly appreciated!
