[ovirt-users] Vnc client from windows 10

Hello, I'm trying to have a user connect to the console VM through vnc protocol, but without the virt-viewer application. The client is Windows 10. I have tried some options without success, with tightvnc, ultravnc and realvnc but all of them give error about syntax. Any native client suggested/recommended with windows 10 and oVirt? Tried also noVnc that works from a Linux client and so I'm sure all is ok at oVirt side, but from Windows 10 and chrome 61 I imported the certificate in trusted root authority but nevertheless I get the error Any hints? Thanks, Gianluca
