network issue after Control Node reboot
Hello,
I installed OpenStack in a VirtualBox environment following instructions from http://docs.openstack.org/training-guid … e.xml.html. The issue is about Control Node virtual machine. I installed Ubuntu 12.04 Server LTE on the virtual machine then I installed all OpenStack services.
At the end of installation, everything looked OK (ping to external sites worked fine) so I made a snapshot of Control Node configuration.
The issue happens when I reboot the Control Node virtual machine, all ping instructions to external domains (or IP addresses, including host machine) generate unknown host message.
I performed only the two following actions between install and reboot:
- Adding line "ServerName localhost" in /etc/apache2/httpd.conf file in order to avoid message "Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName".
- apt-get install --reinstall iscsitarget-dkms due to message "iscsi-target fatal module iscsi_trgt not found"
During startup, all services are [OK], I just have messages:
Waiting for network configuration
Waiting an additional 60 seconds for network configuration
Booting system without full network configuration
I read this message was due to existence of 2 gateways in /etc/network/interfaces file but I don't know if it's a severe issue.
/etc/network/interfaces content (comments removed) :
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.10.10.51
netmask 255.255.255.0
gateway 10.10.10.1
auto eth1
iface eth1 inet static
address 192.168.100.51
netmask 255.255.255.0
gateway 192.168.100.1
auto eth2
iface eth2 inet dhcp
/etc/hosts content:
127.0.0.1 localhost
127.0.1.1 ControlNode
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
/etc/resolv.conf content:
nameserver 80.10.246.2
nameserver 80.10.246.3
I tested several corrections in network files but they didn't resolve my issue. Help would be appreciated.
[UPDATE] I initiated another scratch install of the Control Node and I noticed the issue happens after modifying /etc/network/interfaces. If I remove the "gateway 10.10.10.1" line, it's OK. So my question is : Is this line really necessary?
