[drubenstein]

What version of fleet are you using (fleet version --full)?

fleet - version 2.6.0
branch: master
revision: d3849d8
build date: 2020-03-24T17:27:31Z
build user: zwass
go version: go1.13.4

What operating system are you using?

RHEL 7

What did you do?

Rebuild stateless RHEL 7 workstation in a RHEV environment. They get new MAC addresses but have the same hostname.

What did you expect to see?

Hosts in Fleet reenrolled

What did you see instead?

Hosts enroll as new hosts instead of using the existing enrolled host.

This is because hosts are not uniquely identified by hostname. They are uniquely identified by information stored in the osquery RocksDB database. If you want a cloned host to appear as the same host you will need to copy over the osquery db.
