[ovirt-users] Spice lags using a proxy / Spice foldersharing in oVirt / spice driver for win10

Good evening everyone, I am Marco from Germany and I currently setup a oVirt environment in our data center. The current environment are 1 dedicated engine and 6 oVirt Hosts. I have three questions which I didnt get answered very well during my research in the WWW during the last days. So it would be very helpfull if someone of you can support me. We are using the cluster for normal VM usage and for VDI desktop virtualization with the Spice protocol. 1. Question We are using a spice proxy because we have some VMs reachable via the Engine and Spice external. Since we are using the proxy some users are observing some disconnects of the USB redirection and sometimes mouse and keyboard are not working in the session so that we have to restart the console. Are there some of you also using a proxy and may had the same behaviour and a workaround or fix for this? 2. Question We want to use the Spice foldersharing function but it is always greyed and not usable for us. I dont find anything in the web about the function in the Remote viewer. What is necessary to use it? (Linux and Windows clients) 3. Question The last question is about future usage of the cluster for VMs running Windows10 (and other microsoft distributions of this generation like Server2012 etc). Is there a way getting the spice video drivers working with this operating systems? The official statement I always read is that there is no official driver at the moment available. thanks a lot and best wishes from Cologne in Germany Marco
