The virtual machine assigned to the user hasn’t HA attribute, the user require to test the virtual machine’s HA attribute, how to modify the virtual machine which hasn’t the HA attribute as to the one which has the HA attribute?
We suggest take this operation in the idle period.
Use the “pgAdmin III” tool to login in the master ESC node, select “eucalyptus” database, and execute:
update vm_instance set is_enable_ha ='TRUE' where instance_id=' the ID of the virtual machine which is needed to modify its HA attribute'
After completing the modification, restart the ESC process: sh /opt/setup/eucalyptus-cloud restart
Then the virtual machine now has the HA function.
