If relate to support issue, I believe we can raise case to Redhat and Nutanix support.
But I focus on Redhat subscription issue.
If RHEL VM are running in ESXi, we can use VM data center subscription which can help for cost saving.
If RHEL VM are running in AHV, we need to order per unit subscription. Each subscription cover 2x VMs. We need to pay more subscription cost for RHEL VMs if running in Nutanix AHV farm
