Hi,

I'm trying to modify Hyper-V virtual machine setting with "ModifyVirtualSystemResources" method, it works fine.

But when vm has snapshots, I get code "4096" and any changes to machine.

Any ideas?

The snapshots of a running OS might not be able to handle those changes. A snapshot that was taken when the virtual machine had 4 processors and are restored with 2 processors won't work probably. I think the settings of the VM aren't stored with the snapshot and therefor changing the configuration and restore a snapshot doesn't work. The configuration GUID doesn't match with the snapshot.

Good luck!
