My Laptop only has 4GB and I run 10 in a VM on it with no problems (I am just checking out the features, trying the new style apps, not using as a replacement yet)
Not tried in the latest build, but in previous one win 10 worked perfectly fine on 1GB ram in a VM
Depends what you want to run/test on it, modern style apps should auto suspend themselves if running out of ram, which you don't notice unless checking in taskmanager at amount of ram used (unless latest build has changed this, not checked that yet)
