Hi All, I like to get an idea on the costs of using Hyper-V on an Intel Xeon 5317 Prozessor, 12C/24T. I plan to run 2 VMs on the machine. Based on my current understanding, the hypervisor is for free. But the GUI requires a license which runs around $1.4k. Thanks in advance, --Roman

I've installed an extra 500GB SSD to my server that will only be used as the disc for a single VM; it won't be utilised for cache, appdata, or anything else. Is it better to set it up as a cache pool device and use it to store only one vdisk file? I'm hoping to receive the greatest possible...

I do not use a VM. Whether or not is it a good idea to enable virtualization based security or not?

In this video I spent some time with David Hepkin, a member of the Windows engineering team working on Hyper-V, to get a better understanding of the Windows 10 Virtual Secure Mode. I've had the good fortune of learning a lot about Isolated User Mode with several folks in the kernel team. In this...
