Too many VMs

As part of my work life I regularly need to run windows development software on my Mac. Typically for a client engagement. This is a really convenient setup. I can take a snapshot before I start work on something new and then at the end roll back to the original state ready to work on the next project.

One of the downsides I have encountered recently is the need to keep all these machines up to date with patches and other software updates that seem to be part of everyday life.

Don't get me wrong I think its great that we have this steady stream of updates to make things better but when you start multiplying this up for the VMs I have on my machine the effort to keep them up to date starts to be become a bit of a pain.

I think it is time to start rationalising to a smaller number - just so I can keep them up to date.
