Explanation

Cross-hypervisor Disaster Recovery (e.g., from ESXi to AHV) requires that Nutanix Guest Tools (NGT) be installed on the source VMs. During a cross-hypervisor recovery event, NGT performs in-guest driver injection and reconfiguration, ensuring the VM boots correctly on the target hypervisor by swapping out hypervisor-specific drivers (e.g., VMware VMXNET3/PVSCSI) for AHV-compatible ones (e.g., VirtIO). Without NGT installed on the source VM, the VM will fail to boot properly at the DR site because it lacks the correct drivers for the new hypervisor environment.
