>> Cpu: I5 3330
>> Ram: 12GB DDR3
>> HD: 3 x 4TB(NAS) + 1x120GB (Ubuntu 14.04)
>> GPU:Nvidia gtx 970 directCu mini
>> DVB-S :Dvb-Sky S952 pci express

>> I'm currently using my host for these operations:
>> -Rtorrent + filebot + irssi + Rutorrent
>> - Kodi 14 Client
>> - Vdr Server
>> - Mysql server for Kodi central repository
>> - NFS server for exposing my nas drives
>> - Some cron jobs to update kodi repository

>> Assigned 3vcpus pinning 0-2 with virt-manager ui.
>> Assigned a raw image of 100GB for testing. Virtio for disk and network.
>> There's a bridge br0 on the host machine to provide connectivity.
>> Using huge pages also.
>> Latest ovmf from git.

>> I use it as a steam streaming server by using only wired ethernet gigabit.

>> My problem is only performance.

>> When I fire up a game,qemu process use 90% of 3 cpus and I have framerate

>> I used in the past proxmox for my kvm needs with a i5 3470 and

>> The last thing that I'm going to do is to use a empty installation of
