Elastic Disaster Recovery with Nutanix AHV

Hello, I'm attempting to use Elastic Disaster Recovery to restore on premise Nutanix AHV VM with one 500GB drive. I have the VM fully replicated and can successfully initiate a drill.

When initiating a recovery drill with the default launch template here's what happens:

1. Conversion + Successful snapshot
2. Recovery instance launched with only one 1GB volume called "AWS Elastic Disaster Recovery Base Snapshot"
3. Recovery instance is stopped, and then the 500GB drive gets attached, the 1 GB volume gets removed, but cannot be started up again.

When initiating a recovery drill after editing the template to include an ubuntu ami with a root volume of 8GB:

1. Conversion + Successful snapshot
2. Recovery instance launched with the 8GB root volume
3. Recovery instance is stopped, and then the 500GB gets attached and the 8GB volume removed, but cannot be started up again.

The DRS documentation says Nutanix VMs are supported here - https://docs.aws.amazon.com/drs/latest/userguide/drs-support-Nutanix.html The VM is running a supported version of Linux and meets the prerequisites outlined here - https://docs.aws.amazon.com/drs/latest/userguide/installation-requiremets.html

Do I need to take any extra/special steps to successfully launch a recovery instance since I'm replicating a Nutanix VM and not a traditional server? Any help here is appreciated, thanks.
