This is a sort of minor nit picky issue I will admit, but I have noticed that there on in the test Hyper-V hosts that I have setup, both of which have 8 GB &nbsp;of RAM, I can only setup two VMs of 4 GB and 2GB. &nbsp;In VMware based setups I could get away with 4GB and 3GB, lol I swear I remember even 4 GB and 3.5GB, leaving only 512 MB for the host. &nbsp;But with Server 2012 Hyper-v it wont let me do this. <br />
<br />
When I RDP into the host with the two 4 and 2 GB VMs and fire up task manger, I see that it is only using 6.7 of the 8GB. &nbsp;I am guessing 6GB for the 2 VMs and 0.7 for the host, how do I gain access to all of the RAM?<br />
<br />
Second embedded question, assuming this is a &quot;that's just the way it is&quot; architecture type thing, does this percentage of 16% non usable memory exist even if I had more RAM, like 300 GBs or something very large?<br />
<br />
Thanks for the info.

Squeezing more Memory Out of a Hyper-V host?

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
