Open Stack

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.


Regards,

flat network mode

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
