### problem
While documentation specifies NFS-only support for importVM,
SharedMountPoint is also a filesystem-based shared storage type. Its exclusion
seems unnecessary and may indicate a gap. Allowing SharedMountPoint or
clarifying the rationale for this restriction would help improve consistency.
Importing a VM using importVm having its qcow2 disk on SharedMountPoint
primary storage pf the KVM host fails with error:
**Unsupported Storage Pool → Disk not found or is invalid**
This happens during CheckVolumeCommand, causing the import workflow to abort.
SharedMountPoint storage is filesystem-based (similar to NFS from a
hypervisor perspective), but the current implementation appears to allow only
NFS for import, leading to this failure.

```
Note: Both NetworkFilesystem and SharedMountPoint represent shared
file-based storage accessible across hosts, and importVM should not be
restricted to NFS-only.
### versions
CloudStack version: 4.22
Hypervisor: KVM
Primary storage: SharedMountPoint (clustered filesystem mounted on all hosts)
### The steps to reproduce the bug
1. Configure a KVM cluster with SharedMountPoint primary storage
2. Ensure storage is mounted on all hosts at the same path
3. Attempt to import a VM by providing a QCOW2 disk using the importVm API
4. Observe failure with "Unsupported Storage Pool" and "Disk not found or is
invalid"
### What to do about it?
ImportVM should support SharedMountPoint primary storage (shared
filesystem-based storage) similar to NFS.
Validation logic should allow:
NetworkFilesystem (NFS)
SharedMountPoint
Instead of restricting import to NFS-only.
Both NetworkFilesystem and SharedMountPoint represent shared file-based
storage accessible across hosts, and importVM should not be restricted to
NFS-only.
