Appendix A: Troubleshooting Hyper-V discovery
The following section provides troubleshooting information for Hyper-V discovery
and collection on Virtualization Manager.
Why does Virtualization Manager not receive
information from Hyper-V Hosts?
If you have never been able to discover or collect information from Hyper-V hosts,
one of the following conditions may be true:
l Missing administrative credentials
l WMI is not enabled
l WMI Counters must be reset
l Firewall is misconfigured
l DCOM is not enabled
l UAC is enabled
l RPC in not enabled
If these conditions are not met, Virtualization Manager cannot collect information
from the Hyper-V host.
If data collection stops after the initial setup, it can be related to new security
policies or a group policy that supersedes your changes. This document is not
intended to troubleshoot this scenario.
For further troubleshooting information, see the Microsoft TechNet and the
Microsoft Developer Network websites, and search for WMI troubleshooting.
