Thread: Configuring Dual Ethernet with UEC 10.4

i have installed unbuntu 10.4 cloud server. have 2 servers:
front end server (clound-fe):
· 2 dual core 32 bit xeon processors (they not support virtualization)
· 2 ethernet ports
o eth0 – used public connectivity (100 mbit)
§ ip address 192.168.3.30
§ network 192.168.3.0
§ netmask 255.255.255.0
§ gateway 192.168.3.1
o eth1 – used public connectivity (gigabit lan)
§ ip address 192.168.4.30
§ network 192.168.4.0
§ netmask 255.255.255.0
· i loaded except node controller
· i set cluster (cloud-nine) use ip range use 192.168.3.100 – 192.168.3.250
node controller (cloud-nc-1)
· 4 dual core 64 bit xeon hyper-threading processors support virtualization
· 2 ethernet ports
o eth0 – used public connectivity (100 mbit)
§ ip address 192.168.3.31
§ network 192.168.3.0
§ netmask 255.255.255.0
§ gateway 192.168.3.1
o eth1 – used public connectivity (gigabit lan)
§ ip address 192.168.4.31
§ network 192.168.4.0
§ netmask 255.255.255.0
· i told installation cloud-fe server list of available components fewer , installed them on one.
· i didn’t set cluster here, should have?

saw eth1 set point bridge configure in /etc/network/interfaces made static:

now realize reference bridge there hypervisor kvm needs use, or think was. removed it.


question:

1. how should have configured interfaces in order support hypervisor, 1 public network eth0 , 1 private network cloud use?
2. do need change configuration in eucalyptus.conf? @ point stock have not made changes.


thank in advance,
michael

if use following:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
address 192.168.3.30
network 192.168.3.0
netmask 255.255.255.0
broadcast 192.168.3.255
gateway 192.168.3.1
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0


need same eth1? create new bridge? realize bridge communicating vm ethernet connection. if not value in having seperate private ethernet connection cloud? need make use of it?
