If I want to run an operate splunk 6.3 on Microsoft Hyper-V, what are the requirements? Is this supported?
Yes, Splunk can run on a Hyper-V VM. Performance will not be as good as physical hardware due to hypervisor hardware abstraction.
Check out the virtualization section for requirements here -> http://docs.splunk.com/Documentation/Splunk/latest/Capacity/Referencehardware
