Problem with VRA and VPG Creation Failure on Hyper-V Due to Windows Updates
Viewed 563 times
An administrator my have difficulty installing VRAs or creating VPGs in Hyper-V due to Windows Updates deregistering a necessary file on the host itself.
During some of these updates, a crucial file is deregistered on the host:
“C:\Program Files\Microsoft System Center 2016\Virtual Machine Manager\setup\scvmmswitchportsettings.mof”
Cannot install VRAs.
Cannot create VPGs
Existing VRAs might go into a Ghost state.
Some of the VRA installations will fail with an error mentioning “WsManMIGetInstanceFailed”.
This can happen because of several Windows updates, such as KB4467684 and KB4494440.
The file needs to re-compiled via running the following command on the Hyper-V host (directory path may differ):
mofcomp "C:\Program Files\Microsoft System Center 2016\Virtual Machine Manager\setup\scvmmswitchportsettings"
