Do Hyper-V virtual Windows 7 desktops need a pagefile?

We have (35) Windows 7 virtual desktops running across (4) Windows 2008 R2 Hyper-V hosts (running on a SAN). These are a mix of 32 and 64 bit workstations. The 32 bit workstations are maxed out at 4 GB RAM The 64 bit workstations are set at 8 GB. My question is, can I do away with the pagefile on these VMs and gain performance (or lessen the I/O on the SAN)? If I can't, is it better, as I've read in other places, to create a small (4-8 GB) new VHD and put the pagefile on that drive? Or, leave it as is and not mess with this?

You should treat the VMs like they were regular physical machines.  Meaning performance would decrease without a pagefile.  However, moving the pagefile to another virtual drive will increase performance.

We don't change the defaults for desktop OS based VMs. We leave the page file on.
