That's a bit odd.
 
 
When I run euca-describe-instances I see the instance running:
 
 
~# euca-describe-instances
RESERVATION     r-8qqt14x2      novatest        default
INSTANCE        i-00000001      ami-15bd14eb    192.168.140.114 192.168.140.114 running novatest (novatest, spe-lab)    0               m1.tiny 2011-08-12T13:29:24Z   nova

 
And my groups are set up as follows:
 
 
~# euca-describe-groups
GROUP   novatest        default default
PERMISSION      novatest        default ALLOWS  icmp    -1      -1      FROM    CIDR    0.0.0.0/0
PERMISSION      novatest        default ALLOWS  icmp    22      22      FROM    CIDR    0.0.0.0/0

 
 
However when I try to query the IP of the instance, that I cannot ping or SSH, I get nothing
 
 
~# euca-describe-addresses 192.168.140.114
~#

So I'm going to check my routes, networking and try adding new rules using euca-authorize

i have downloaded image from http://cloud-images.ubuntu.com/releases/11.04/release/ubuntu-11.04-server-uec-amd64.tar.gz

and also facing the same problem, cannot access or my running instances.

However, I am facing another weird problem here. I can easily launch an instance from the dashboard, but when I try to run it from command line, I lost my internet connection, and this happens to all of my PCs connected to the same router. To solve this I have to restart the network of the controller node to get connected again.

	Hi,
	
	I have a similar problem but my networking seems to be setup correctly.
	
	Does one need to authorise SSH as well ? I also, cannot ping or SSH to
	any running instances.

	Hi,
	I found a solution. The problem was, that I had no ip on that host in
	that subnet.
	Therefore all packages to 192.168.27.0/24 were sent to my default gw,
	which was wrong.
	I created a "virtual" interface on the bridge, where the instances are
	connected to.
	
	br100:0   Link encap:Ethernet  HWaddr 00:22:19:6d:87:3a
	         inet addr:192.168.27.100  Bcast:192.168.27.255
	Mask:255.255.255.0
	         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
	
	After that, the network is running and I'm able to ping my instances.
	
	But now I'm looking into flat dhcp mode, because I'm going to have
	windows instances, and the ip injection doesn't work with windows afaik.
	
	Cheers,
	Chris
