I currently have a Oracle Virtual Box Setup with Azure on a windows 10 Machine. It works and everything but I realized the performance isn't the best. So currently I am using a D4s_v3 series VM for this but setting up a Kali image with Virtual Box is pretty slow. For eg. it will take 10 minutes to get to the Kali login screen vs it taking less than two minutes on my Windows 10 host machine.
Does it matter the series that is used or is this just an expected performance drawback of Nested Virtualization within Azure?
