I ask because in the architecture diagram on wikipedia, it indicates the "host" OS (root partition) is on a par with the "guest" (child partition), with Hyper-V components below all of them.
http://en.wikipedia.org/wiki/Hyper-V
If that is the case then the host OS is itself being virtualized, so will suffer from that overhead even if there are no guests installed.
Questions:
- Do the hypervisor/vm-bus only get installed once you select the Hyper-V role, or are they below the surface on every Windows Server R2?
- Does adding the Hyper-V role require a reboot?
- How does the presence of the Hyper-V components affect performance of the root partition?
- Is the performance of root identical to child partitions?
Note: I am using Windows Server 2008 R2.
Thanks, Jack
