There are more advantages:
- Generation of heartbeat from guest to host for vSphere HA solution to determine guest's availability.
- Quiescing guest file systems to allow host to capture file-system-consistent guest snapshot/backup

Since the anchors are managed by the RIPE Atlas Team: can you tell us if virtual anchors have Open VM Tools (for ESXi) or QEMU Guest Agents (for KVM) installed by default, so that Hosts can shut down virtual anchors gracefully, in case of a maintenance?

This isn't necessary.  ACPI-triggered shutdown in guests works just
fine, and is enabled by default in every widely deployed hypervisor.
