We have an IBM sytem x3650 MT 7979 running as a Vhost. I verified that the machine that we bought has a 64 bit architecture but it was configured as 32 bit. the vhost has allocated 4 virtual servers that runs on 32 bit windows OS platform. If we want it configured as 64 bit, is there a detailed instruction on how to do this? Someone told me that we need to reinstall the hypervisor?

You're going to have to reinstall.....

Yes, both the host OS and the VMs. There are no cross-architecture in-place upgrades for Windows. – jscott Jan 10 '13 at 3:07
