Hi Tim!
Maybe Iḿ doing something wrong but running morph-vm makes the server unusable if the second disk is smaller then 1TB. Not running morph-vm makes the second disk not used. The disk1 the server ships with is to small for use, fills up when trying to patch the server.
EDIT: ah , you did meen that labvm setup is not supported in the same way in AWS as local ? So 1000 is the smallest supported size ?
