I've run a few tests on my lab environment on features support based on a hypervisor. It may come useful when you're planning for a migration to the different hypervisors.
Lab environment:- Veeam Backup & Replication v10
Here is my test result:
Test 1: Instant VM Recovery
Test 2: Full VM Restore (Entire disk recovery)
Test 3: Instant Disk Recovery
Test 4: Storage Snapshot
Hope this helps.
