one 5.12 sqlite error

We have successfully set front end “5.12” and while installing kvm node its showing error “sqlite3 missing” error, then I changed 5.10 and installed kvm node.

After that added host in the front end its showing below error

Hello @Ajith,

Can you confirm that your frontend is running OpenNebula 5.12 and that you have installed the opennebula-node-kvm for 5.12 version in the node?
