Microsoft has integrated a limited version of Hyper-V, called Client Hyper-V, to Windows 8 and Windows 8.1.
Similar to the Windows Server Hyper-V version, the Client Hyper-V edition targets power user who need to virtualize several operating systems and run them on a single workstation. Microsoft added Hyper-V Windows 8 to the Pro and Enterprise Editions of Windows 8 only, and the reason for that was most likely to compete with VMware Workstation.
What are the Limitations of Windows 8.1 Hyper-V compared to the Windows Server edition?
First, Remote FX, which virtualizes GPUs, is not supported. Cluster Shared Volumes aren’t accessible and, hence, live migrations won’t work either. Hyper-V replica is also restricted to the Windows Server version. Hyper-V Virtual Fibre Channel, SR-IOV (on 32 bit) networking, and ability to share VHDX files between virtual machines has also been removed.
Hyper-V VSS Writer Is Not Offered
Another crucial difference not mentioned in many Microsoft documents is the absence of the Hyper-V VSS Writer. This component is necessary to create application consistent live backups of Hyper-V virtual machines.
Without this particular writer, all backups taken from Hyper-V Client VMs are crash consistent instead of being application consistent. See this discussion: http://backupchain.com/i/vss-crash-and-application-consistency-for-hyper-v-and-vmware-backups
However, crash consistent backups are fine in many if not most circumstances, as modern data services are transaction based (even NTFS is) and rollback when outages occur.
