The NVMe-oF KVM adapter refused every template copy request from the adaptive storage orchestrator with UnsupportedOperationException, which made it impossible to use an NVMe-TCP pool as primary storage for a VM root disk: every deploy that landed a root volume on the pool failed as soon as CloudStack tried to lay down the template. Implement it the same way FiberChannel (SCSI) does: the storage provider creates and connects a raw namespace ahead of time, then the adapter resolves the host-side /dev/disk/by-id/nvme-eui.<NGUID> path via the existing getPhysicalDisk plumbing (which will nvme ns-rescan and wait for the symlink if the kernel has not yet picked it up) and qemu-img converts the source image into the raw block device. User-space encrypted source or destination volumes are rejected: the FlashArray already encrypts at rest and layering qemu-img LUKS on top of a hostgroup-scoped namespace shared between hosts is not a sensible layering. Source encryption would also break on migration because the passphrase does not travel. With this change a CloudStack KVM VM can have its ROOT volume on an NVMe-TCP pool (tested end-to-end on 4.23-SNAPSHOT against Purity 6.7.7: template copy, first boot, live migrate with data disk, VM snapshot with quiesce, and revert all work).
