This issue can be caused by an unresponsive virtual machine in the vCenter Server inventory.
Identifying the unresponsive virtual machine can be difficult if there are a large number of ESX hosts or virtual machines in the inventory.
To identify the unresponsive virtual machine, try one of the following methods:
- Use vSphere PowerCLI to identify the unresponsive virtual machines.
- Download and install vSphere PowerCLI. For more information, see the vSphere PowerCLI Installation and Administration Guides.
- Click Start > Programs > VMware > VMware vSphere PowerCLI > VMware vSphere PowerCLI to launch PowerCLI.
- Run this command to access the vSphere Server:
Connect-VIServer -Server <VI_server_address> -Protocol <hypertext_transfer_protocol> -User <user_name> -Password <password>
- Run this command to identify the unresponsive virtual machines:
get-vm | get-vmguest
The unresponsive guest times out on the query.
After identifying the unresponsive virtual machine, restart it.
