When I start the VM, the interface is configured properly automatically, and then shows as "up". But I would like to understand if there is a way to manually set the interface back to up without having to set its IP address again (it is already configured and the IP shows under "VBoxManage list hostonlyifs").

Which host OS? Normally there's no need to do this, as interfaces 
shouldn't be disabled randomly... it's to my knowledge not easily 
possible without annoying (and disruptive) approaches like deleting the 
host-only interface and recreating it with the same settings.
