Node Controller not working on UEC

[strychn9ne]

I've got a cloud that just up and died with this exact symptom. What sucks is that it was working fine until about three hours ago, so it's not the install. I've tried everything suggested here to no avail. Sure, a reinstall might fix it but I really can't do that right now.

I'm experiencing simular issues. I could start my own thread..but this seems to be the same issue.

The thing that bugs me, is the availability-zones come and go as the please. One or two nodes will work at any given time, but they never stay up for long.

registered nodes:
x.x.x.x cluster1
x.x.x.x cluster1
x.x.x.x cluster1
x.x.x.x cluster1

AVAILABILITYZONE cluster1 x.x.x.x
AVAILABILITYZONE |- vm types free / max cpu ram disk
AVAILABILITYZONE |- m1.small 0000 / 0000 1 192 2
AVAILABILITYZONE |- c1.medium 0000 / 0000 1 256 5
AVAILABILITYZONE |- m1.large 0000 / 0000 2 512 5
AVAILABILITYZONE |- m1.xlarge 0000 / 0000 2 1024 10
AVAILABILITYZONE |- c1.xlarge 0000 / 0000 4 2048 15

and 3 mins later

another 3 mins

Its very fustrating, seems so damn close, but never sticks around.

I have been able to get a VM up and running and SSH it. However I keep losing availability-zones...

Eucalyptus require a precise time synchronization between all the physical hosts it runs on. If time synchronization is lost, the symptom is the one you're describing.
Install the ntp server on all the machines, and wait for a little while (~1h) until the time adjustments complete. You should be fine then.
