Hi @mgolson and @jmulliken - yes, I recall when Karen was working on getting that disk image working with a local EaaSI deployment!
You’re correct that bootable disk images (or VMs from another platform, like a VMDK) don’t quite fall under either Software or Content resource definitions (and it wouldn’t work as you would wish even if you did import as one of those types). The “Import Environment” workflow that was present in EaaSI versions prior to the hosted service would be the appropriate one here, but we made the decision to launch the hosted service without that functionality until EaaS updates to the “Import” and “Create Environment” workflows could get merged with the Emulation Project design in the updated EaaSI UI. That latter work is still ongoing, but we do expect it to be tested in the next month or so and merged into the hosted service in the fall.
You are further correct that such a large file could potentially cause import problems through a browser upload - but this would actually be a rather good stress test for us, since this would not be an uncommon size for an existing, relatively recent VM. Would you be willing to share the vmdk (and config file) with me privately? (e.g. send me a download link here or via email) so that I could use it as a sample? It’s possible I could also get it running as an Environment for you all manually in the hosted service.
