But how does the Jenkins libvirt plugin know the IP address for the VM,
unless you enter it in this field in the Jenkins UI?

The easiest way is to have the openjdk installed in the VM, so that Jenkins
can ssh in and run
jobs.  However, there is also the Publish Over SSH Plugin (
https://wiki.jenkins-ci.org/display/JENKINS/Publish+Over+SSH+Plugin )
which allows Jenkins to SSH into a remote host and run different commands,
instead of starting
a full Jenkins job, which requires the openjdk to be available.
