There are many versions and variations of Windows with different levels of support for the features provided by XenServer. This section lists notes and errata for the known differences. Multiple VCPUs are exposed as CPU sockets to Windows guests, and are subject to the licensing limitations present in the guest. The number of CPUs present in the guest can be confirmed by checking the Device Manager. The number of CPUs actually being used by Windows can be seen in the Task Manager. The disk enumeration order in a Windows guest may differ from the order in which they were initially added. This is a behavioral artifact between the paravirtualized drivers and the PnP subsystem in Windows. For example, the first disk may show up as "Disk 1", the next disk hotplugged as "Disk 0", a subsequent disk as "Disk 2", and then upwards in the expected fashion. Windows XP does not support disks larger than 2TB (terabytes) in size. See this article in the Windows Hardware Developer Central website. | |||||||||||||
