Windows server 2008 R2 Hyper-V

Hi,

In Windows server 2008 R2, with Hyper-V, the memory for the VMs is sourced by the Page File on the host server or from the total physical RAM on the host.

I have to increase the memory size on one of the VMs and it says not enough resources.

So should I increase the Page File size on the host or should I increase the Physical Memory on the host?

Thanks,

It is from the physical ram.  if you are having performance issues then you need to increase memory on the host.

Hi,

I am not having performance issues.

But I need to increase the size of the memory in one VM.

But it says insufficient sources available.

So should I  install more RAM on the Host?

Or Should I increase the size of the page file on the Host?

Thanks,

How much RAM do you have on the host - how many VM's and the RAM on those and especially the one in question  - hyper-V, etc.. are meant to over-commit memory and CPU.  Are any of the other VM's having issues?  Is SQL installed on this VM by chance?

Host RAM: 104 GB.
Page file size on The Host: 106 GB
Total memory usage for VMs (total 7 VMs): 102 GB.
Yes SQL is installed on the VM, whose memory I need to increase, from 16GB to 32GB.

Cool - I would *if possible* of course increase memory on the host and if you want increase swap.  Here is an article on limiting SQL memory usage - you could probably just do this:
