Hmm... It could be a duplicate of bug 460089 (solved in 7.3, in karmic-
updates now). Some update would trigger a cluster controller restart
(either eucalyptus-cc update or some reboot) and network status would be
lost.
I'll mark as invalid, please reopen if you can reproduce with the latest
(and
It looks like the problem has not happened again in a while. I've had
an instance running for almost a month now, and the IP Address has not
been lost:
$ euca-describe-instances
RESERVATION r-44510791 admin default
INSTANCEi-4A870825 emi-230B11AE172.23.46.78172.19.
Joseph: how is the "cluster controller" main IP address assigned ? Is it
DHCP ? If yes, could there have been an issue at the end of the DHCP
lease (IP address change after a multiple of 3 days ??)

I restarted my instance on Monday after the public IP address changed.
The initial issue happened after three days. However, it's now been
four days, and I have not been able to reproduce it again. It now seems
there is not a pre-determined amount of time before the IP address
expires.

Dustin: sounds like yours is slightly different, you end up with 0.0.0.0
rather than the private IP, and you hit it after one hour, rather than 3
days. I'd suggest opening a separate bug, if you can reproduce it. We'll
merge the bugs if they happen to have the same root cause.

IIUC the public IP address is not handed by DHCP but by Eucalyptus
itself, from a pool defined at VNET_PUBLICIPS. That doesn't mean there
isn't a timeout involved in that mechanism as well.

I'm reviewing the logs now to see if there are additional details.
I think the max-lease-time is running out which is defined in
/etc/dhcp3/dhcpd.conf. The two configurable settings are:
default-lease-time 600;
max-lease-time 7200;
7200 is three days, which is the right about when my public IP
Maybe some issue with the DHCP lease not being renewed. Takes some time to
reproduce, unfortunately...
Joseph: would there be anything in the logs (host side or guest side) about
this ?
