We have a machine running Windows 2008 Enterprise with the Hyper-V Server role. The machine has 48 GB of RAM, and a RAID1 of just 74 GB.
The VMs are stored on a SAN.
My question is, does the Hyper-V host server itself need a big swap file for anything?
I know the recommended size of the swap file is at least 1.5 times the amount of physical memory installed, but this is more than the amount of physical disk space. I could store part of the swap file on the SAN but I'd rather not do that.
In theory, being just a VM host, the machine should be able to run without a swap file at all, but I have my doubts. Anyone with first hand experience on this?
