OVM

Migrate OVM Manager to a Different Server

admin

For whatever reason you ever need to migrate an OVM Manager to a different host this would be helpful. I can't imagine that this would need to happen that often but I recently did need to cut it over from a Virtualbox instance to an OVM Hypervisor. This is the OVM 3.2.1 local mysql(not Oracle XE) DB version.

Find the source UUID:

# more /u01/app/oracle/ovm-manager-3/.config
DBTYPE=MySQL
DBHOST=localhost
SID=ovs
LSNR=49500
OVSSCHEMA=ovs
APEX=8080
WLSADMIN=weblogic
OVSADMIN=admin
COREPORT=54321
UUID=0004fb0000010000434a8179cda0edbd
BUILDID=3.2.1.516

Copy recent backup and stage on new host. You can make a manual mysql backup or I just used the latest Auto backup:

# tar cpf a.tar AutoFullBackup-20130501_201957
# scp a.tar root@172.16.97.155:/root

Some pre-requisites the install would be pointing out:

# grep oracle /etc/group
dba:x:501:oracle

# tail -3 /etc/security/limits.conf
* soft nofile 16384
* hard nofile 65536
# End of file

[root@hovmmanager a]# ulimit -aH
...
open files                      (-n) 65536
...

Install Manager on new host using old UUID:

# pwd
/mnt/a

# ./runInstaller.sh --uuid 0004fb0000010000434a8179cda0edbd
