Andi and Rafael,
Thanks a lot for your replies!
Here is my /etc/network/interfaces :
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 172.241.0.101
network 172.241.0.0

Hi all!
Just joined the mailing list. I'd like to do some development on
the project (probably Nova). Some questions regarding how to start:
Q1. I'm trying to setup Nova in a virtual environment -
http://uksysadmin.wordpress.com/2011/02/17/running-openstack-under-virtualbox-a-complete-guide/ -
on a Windows host. I've successfully started an instance and
assigned it a network address:
aron@cloud1:~/openstack/cloud/creds$ euca-describe-instances
RESERVATIONr-k6e14a5wmyprojectdefault
INSTANCEi-00000001ami-0a892947172.241.0.110.0.0.3runningopenstack
(myproject, cloud1)0m1.tiny2011-08-02T20:28:46Znova
but I'm unable to connect to the address (neither from the guest
nor from the host):
From the guest:
aron@cloud1:~/openstack/cloud/creds$ ping 172.241.0.1
PING 172.241.0.1 (172.241.0.1) 56(84) bytes of data.
From 172.241.0.1 icmp_seq=2 Destination Host Unreachable
aron@cloud1:~/openstack/cloud/creds$ ping 10.0.0.3
PING 10.0.0.3 (10.0.0.3) 56(84) bytes of data.
From 10.0.0.1 icmp_seq=1 Destination Host Unreachable
From the host:
C:\>ping 172.241.0.1
Pinging 172.241.0.1 with 32 bytes of data:
Reply from 172.241.0.1 <http://172.241.0.1>: Destination host
unreachable.
Pinging the guest from the host and vice versa is ok, e.g.:
C:\>ping 172.241.0.101
Pinging 172.241.0.101 with 32 bytes of data:
Reply from 172.241.0.101 <http://172.241.0.101>: bytes=32
time=1ms TTL=64
What may be wrong?
Q2. When I do succeed to setup the environment, can anybody to
point me to documentation on how to write simple code for
OpenStack? Something along the lines of "Hello, world!",
but using some features peculiar to cloud applications.
Q3. I have no technical knowledge about the cloud at all. Can
anybody suggest a learning path so that I quickly can gain the
basic necessary general and specific knowledge to start coding
(i.e. first read the code and know what's flying, then fix some
bugs, etc.)?
Thanks in advance, -Aron
