Welcome to the Linux Foundation Forum!

Exercise 10.2 - No valid host was found. There are not enough hosts available.

When trying to add the second instance (bc2) I continually get the "No valid host was found. There are not enough hosts available." 500 error.

As such, I cannot complete the lab since I cannot log into an instance that will not start or create.

Please advise!

    Sorry for the delay. Are you still experiencing this issue. Could you check to see, do you have any instances deployed? The overview page in Horizon typically shows how may vCPUS and other resources are available and how many are in use.

    As an admin user, under the system tab, how many instances are currently running? The lab 10 has you configure bc1 and bc2.  There need be no other instances running.
