Failed to start Kaleido subprocess on windowsserver 2019-datacenter-core

[DrewScoggins]

I am getting the below stack trace when I try and call write_image on VMs that are running windowsserver 2019-datacenter-core. This command has always worked before on a normal version of Windows, so I was wondering if it had something to do with the more limited install of this version of Windows. As can also be seen, I am not getting anything in the error stream.

Traceback (most recent call last):

Thanks for your interest in Kaleido. We are currently working on an overhaul that might address your issue - we hope to have news in a few weeks and will post an update then. Thanks - @gvwilson

Thanks for the response. We ended up just running on a bigger version of Windows, but if there is eventually a fix for this that would be great.
