Hi All,

Had to move one of my clusters to a new subnet but it is not working (e.g. to  These are the steps I took:

Environment: CS 4.1.1 on Ubuntu 12.04, XenServer 6.1, Shared NFS SR.

1) stopped all instances using cloudstack UI
2) stop cloudstack-management service on MS
3) Used XenCenter to kill the system VMs (no other instances running)
4) Created backup of cloud db.
5) Followed and successfully
changed the IP of hosts.  According to XenCenter everything is good
including SR.
6) Changed IP of MS
7) verified communication between MS and Hosts using ssh and ping with new
8) used sed to search and replace all old IPs with new IPs in cloud backup
sql file (e.g. sed -i.bak 's/192.168.1./10.100.1./g' clouddb.sql).
9) visually verified all diffs in the sql file and made sure no references
to 192.168 left.
10) loaded up new sql
11) search all files under /etc on MS for old IP. found and
edited: /etc/cloudstack/management/
12) start cloudstack-management service on MS

Unfortunately things are not working.  The MS is apparently unable to
connect to the hosts but I can not figure out why from the logs.

Logs here:

Any help recovering is appreciated.  I do not want to have to re-install
and create/import template for each of the instance VHDs.

thank you,
