@xinyanw409 The vsphere-plugin itself depends on github.com/vmware/virtual-disks which needs glibc:

go mod why -m github.com/vmware/virtual-disks
# github.com/vmware/virtual-disks
github.com/vmware-tanzu/velero-plugin-for-vsphere/pkg/ivd
github.com/vmware/virtual-disks/pkg/disklib

https://github.com/vmware-tanzu/velero-plugin-for-vsphere/blob/main/cmd/velero-plugin-for-vsphere/main.go#L25

velero-plugin-for-vsphere/pkg/plugin/volume_snapshotter_plugin.go

Line 24 in 0bfbef3

"github.com/vmware-tanzu/velero-plugin-for-vsphere/pkg/snapshotmgr"

velero-plugin-for-vsphere/pkg/snapshotmgr/snapshot_manager.go

Line 26 in 0bfbef3

"github.com/vmware-tanzu/velero-plugin-for-vsphere/pkg/ivd"

So the dependency should be removed to make sure vsphere-plugin can run in an environment that has no glibc.

Correct me if I'm wrong.
