 | Deploying self-hosted Palette or VerteX to a vSphere environment fails if vCenter has standalone hosts directly under a Datacenter. Persistent Volume (PV) provisioning fails due to an upstream issue with the vSphere Container Storage Interface (CSI) for all versions before v3.2.0. Palette and VerteX use the vSphere CSI version 3.1.2 internally. The issue may also occur in workload clusters deployed on vSphere using the same vSphere CSI for storage volume provisioning. | July 20, 2024     | Self-Hosted         | 4.4.11      |
