There was a problem with the virtual machines and snapmanager. Windows server 2008 datacenter is used as the virtualization server. On it snapmanager for hyper-v (SMHV2.0.2_x64) is set.
The problem is that snapmanager doesn't see new virtual machines (which were got after snapmanager installation) and some old (which worked before snapmanager installation). Prompt how it is possible to force snapmanager to see these virtual machines?
