[ovirt-users] Very Slow Console Performance - Windows 10

[FERNANDO FREDIANI]

Hello Gianluca.

As I mentioned previously I am not sure it has anything to do with SPICE 
at all, but with the amount of memory the VM has assigned to it. Proff 
of it is that when you access with via any Remote Desktop protocol it 
remains slow as if the amount of video memory wasnt being enough and 
have seen it crashing several times as well.
