In case i have to delete and create my virtual machines again du to some configurations problems, will it be possible to use my subscriptions again on the new install?

Try:

subscription-manager register --consumerid

From the manual:

--consumerid=CONSUMERID
              References an existing system inventory ID to resume using a previous registration for this system. The ID is used as an inventory number for the system in the subscription management service database. If the system's identity is lost or corrupted, this option allows it to resume using its previous identity and subscriptions.

As you remove/replace the hosts, I'd expect the workflow to be:

  • note the content hosts original consumerid via subscription-manager identity
  • do NOT remove the content host entry from Satellite or RHSM
  • Replace the system with the new hardware.
  • register to the existing content host record subscription-manager register --consumerid <uuid>
  • update your facts subscription-manager facts --update
  • refresh your subscriptions to ensure your subs match (i.e if you went from a 2 socket system to a 4 socket system) subscription-manager refresh
