Hello, I'd like that say thanks falko for providing such great howtos. I followed the Xen Ganeti howto except used the latest version of ganeti instead of outdated one, just a few minor issues to getting it setup. I've got the cluster instance created, but am having problems with networking. I bring up the interface and can only ping node2 on the cluster, and no where else. The brctl show output of node2 is: node2:/etc/xen# brctl show bridge name bridge id STP enabled interfaces xen-br0 8000.000c29a60c75 no eth0 vif3.0 and on node1 it's: node1:~# brctl show bridge name bridge id STP enabled interfaces xen-br0 8000.000c290ab978 no eth0 Is the vif3.0 causing issues? Are my bridges not setup correctly? Here is my interfaces file from node2: node2:/etc/xen# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto xen-br0 iface xen-br0 inet static address xxx.202.80 netmask 255.255.255.192 network xxx.202.64 broadcast xxx.202.127 gateway xxx.202.126 bridge_ports eth0 bridge_stp off bridge_fd 0 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers xxx.98.98 dns-search domain.com node2:/etc/xen# If there is anything else that could help in resolving this issue let me know. Thanks, -Steve
