[Ci-users] Nested virtualization in centos-ci?

Hi, I'm wondering if something like nested virtualization is 
possible/available/recommended in centos ci.

My use case is that we would like to have a test for mariadb galera and 
this test is hard to be written on one machine + ideally we'd like to 
test real machine to machine workflow.

Is it something we can do in the jenkins?
