I have recently checked memory allocation in a Windows Server 8 DP OS that I have installed using Windows 8 DP Hyper-V. I was stunned to have noticed that 1 MB of RAM in this virtual machine is hardware-reserved. In none of my other VMs equipped with various
OSs is there specific hardware reserve RAM allocation. Moreover, Windows Server 2008 R2 installed in a Windows 8 DP Hyper-V virtual machine would not exist longer than 10 minutes after reboot when specifically denied access to PCI firmware settings (via BCD).
I might be obnoxiously stupid but I would very much like to know what does this 1 MB allocation imply and infer, especially since the hardware RAM allocation size in the parent OS is only 3 MB.
(BTW, the Building Windows 8 blog article regarding minimum Hyper-V for Windows 8 requiurements mentions 4 GB as the minimum amount of RAM. My parent OS (Windows 8 Client DP) has only 3 GB physical RAM and Hyper-V functions perfectly fine. I experience no
problems with simultaneous launch of 2 virtual machines while watching high-resolution movies in a parent OS and snapping desktop and Metro back and forth. So to hell all the talk that Hyper-V is incompatible with low-latency applications. My computer says
it is compatible and I have no grounds not to believe my computer. Virtual machines are connected to the Internet and to each other via a single network bridged to a wireless adapter and my VCMs exhibit better network connectivity than my other physical computer
that uses cable. So to hell all the talk that of 6 months ago in Technet manuals that you are not supposed to use wireless in Hyper-V and that there should be separate external and internal networks for VMs. My computer tells me a different story, and I have
no grounf\ds not to believe my computer. When I initially bought it from an awfcul manufacturer named ASUS with an awful preinstalled Windows 7 Home Basic it had 250 MB hardware allocation and the system was suffering. Now it has only 3 MB thanks to itself,
to the Windows 8 developers and to myself. And it blossoms!)
