Description of problem: When install guest by nfs,it reports "There is an error configuring your network interface. Version-Release number of selected component (if applicable): libvirt-0.8.7-16.el6 qemu-kvm-0.12.1.2-2.153.el6 kernel-2.6.32-128.el6 How reproducible: 100% Steps to Reproduce: 1.Install guest by nfs 2.During installation,it can't find IP address for eth0 and going installation. 3. Actual results: Expected results: It can find IP address for eth0 and can install guest by nfs. Additional info:
I use bridge network on host to install the guest,part of the guest xml file: <interface type='bridge'> <source bridge='br0'/> <model type='e1000'/> </interface>
1. Check the iptable. # service iptables status Table: nat Chain PREROUTING (policy ACCEPT) num target prot opt source destination Chain POSTROUTING (policy ACCEPT) num target prot opt source destination 1 MASQUERADE tcp -- 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535 2 MASQUERADE udp -- 192.168.122.0/24 !192.168.122.0/24 masq ports: 1024-65535 3 MASQUERADE all -- 192.168.122.0/24 !192.168.122.0/24 Chain OUTPUT (policy ACCEPT) num target prot opt source destination Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination Chain FORWARD (policy ACCEPT) num target prot opt source destination Chain OUTPUT (policy ACCEPT) num target prot opt source destination 2.On host, delete the 1th and 2th rules in POSTROUTING chain of nat table. # iptables -t nat -D POSTROUTING 1 # iptables -t nat -D POSTROUTING 1 # iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- 192.168.122.0/24 !192.168.122.0/24 Chain OUTPUT (policy ACCEPT) target prot opt source destination 3.Then I use nat network to install the guest,it also can't work.
It can work well with libvirt-0.8.7-15.el6
This bug is caused by our DHCP server,retest this one and now it works well.So close this bug.
