[Xen-users] VLAN interface stops working after XEN Loads Centos 5.4 XEN
Greetings All, I have installed a second XEN server with a VLAN interface. When XEN loads I my VLAN interface stops working. IE I can''t ping the default gateway. I set it up the same way I did my other server. I''m not seeing any errors on loading. If I don''t load XEN the interfaces work as expected. I''m either missing something or the there is something different between the two. They are different hardware configs. Here is how I have it setup. in xend-config.sxp I have changed the line # It is possible to use the network-bridge script in more complicated # scenarios, such as having two outgoing interfaces, with two bridges, and # two fake interfaces per guest domain. To do things like this, write # yourself a wrapper script, and call network-bridge from it, as appropriate. # (network-script network-bridge-2) <<< changed to network-bridge-2 in /etc/xen/scripts/network-bridge-2 #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=2 netdev=eth0.500 "$dir/network-bridge" "$@" vifnum=1 netdev=eth0 ------------ My interneral network is using the native vlan on this cisco switch ifcfg-eth0 # nVidia Corporation MCP79 Ethernet DEVICE=eth0 BOOTPROTO=none ONBOOT=yes HWADDR=00:1f:bc:03:4e:49 NETMASK=255.255.255.0 IPADDR=192.168.1.177 TYPE=Ethernet My external network is on the VLAN 500 # Intel Corporation 82566DM-2 Gigabit Network Connection # x =''s my public interface address portions which I''ve masked blotted out for this email VLAN=yes DEVICE=eth0.500 BOOTPROTO=none BROADCAST=x.x.x.x HWADDR=00:1f:bc:03:4e:49 IPADDR=x.x.x.x NETMASK=255.255.255.224 NETWORK=x.x.x.x ONBOOT=yes GATEWAY=x.x.x.x TYPE=Ethernet As soon as i load xend the vlan.500 interface stops working. Now this setup is working on my neighboring machine flawlessly.
