Actual results: Unable to spawn instances to a dedicated compute host after undercloud upgrade. Expected results: Instances should be created to a dedicated compute node with --hint force_hosts option after undercloud upgradation. Additional info: I am doing rhosp 13 to 16.1 Fast forward upgrade and referring below link for the upgradation: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html-single/framework_for_upgrades_13_to_16.1/index

Hi Lee Yarwood, Thank you so much for your valuable information, yes after upgrade compute api version is 2.latest. Below is the output for the same: (overcloud) [stack@manager templates]$ echo $OS_COMPUTE_API_VERSION 2.latest Your info works for me, thanks again for looking into this issue and for your precious time.
