  • Does XenServer support dual-core or greater processors?

    Yes, XenServer supports multi-core processors.

  • How many processors can XenServer utilize?

    All XenServer Editions can utilize up to 32 cores total per system.

There isn't a limit on the number of cores per socket, just cores per host.

Just beware that there's a core-per-socket setting in XenServer, only available to paid versions of XenServer. Also, if you're using Windows vms, you've to make sure that there are cpu socket limits on Windows editions.
