Subject error restarting virtual router after upgrading
Date Wed, 27 Aug 2014 09:12:24 GMT
Hi all,
we are trying to upgrade a cloustack 4.3 installation to a 4.4 version. 
Manager and agents (and ssvm and cpvm) runs in a new version and seems 
to be OK but virtual routers are still 4.3.0.

I tried to reboot a router but this does not restart it gives me these 
error messages:

I tried to destroy the router but the new one fails to start in the same 
way.

The other router (4.3.0 version) is still working but I have not tried 
to restart it.

Of course the vmon the network with the router ko can not get out of the 
network.

Management run on ubuntu 12.04, Agents run on ubuntu 14.04. In another 
similar installation of cloudstack 4.3 it's all quite ok (I found a 
problem with a guest network, see 'Unable to start a VM due to 
insufficient capacity' precedent mailing list messages).
