Solution

Update the scvmm server system patches to the latest.

Issue: SCVMM adding Hyper-V cluster fails with agent install timeout.

The SCVMMAgent service on the Hyper-V Host is not running, start it.

Issue: SCVMM Error 20552。

Add the sj\hypervadmin user to the Administrators group on the Hyper-V Host, and then reboot.

And do not use RunAsAccount to add hyper-v cluster.
