In the Windows 10 Insider Preview Build 15002 released to Windows Insiders earlier this week, Microsoft has included a few improvements in Hyper-V.
Hyper-V Manager now has a new page that makes it faster and easier to create virtual machines. With a simple wizard, users can now set up a VM in just a few clicks. After the virtual machine has been created, the confirmation page will allow you to connect to it or enter advanced settings. This new Quick Create feature is still under active development, give it a try and pass on your feedback to the team for more improvements.
In this build, they have also changed how Hyper-V on Windows 10 allocates memory for starting virtual machines. Till now, Windows maintained reserved memory for the Hyper-V host (root memory reserve) so even if task manager showed 2 GB free memory, Hyper-V wouldn’t use it for virtual machines. Also, Hyper-V also wouldn’t ask for applications to release unused memory (trim). This type of conservative memory allocation doesn’t make much sense for Windows 10 and desktop virtualization.
Starting with this build, Hyper-V starts allocating memory in small chunks (to give the OS a chance to trim memory from other applications) and will use all available memory (no root reserve). With this change, the amount of memory shown in task manager accurately reflects the amount available for starting virtual machines.
