There is an other thing that i don't understand.
Like i said, if i set 2gb or <, the VM Word perfectly without problems.
I can set more memory ram only when i disable the internet function in virt-manager...

>> Perhaps you have something eating into RAM of the host. I had my host freezing when I forgot to limit memory utilization in the ZFS. It does not matter what eats into your host RAM - since qemu is just a regular userspace process, it's memory needs (ie those of the guest system) are not "prioritized" as more essential than any other userspace process. If your host does not have enough memory, then the more you allocate in qemu (or libvirt) to the guest system, the more probability that qemu will run out of RAM, effectively freezing the guest OS. At least, this is what it would appear to be (it might be simply swapping, but that slows down guest execution speed by orders of magnitude, so it is effectively frozen)

>> Very very very things. If i set more than 2GB Memory Ram in Virt-Manager for the Guest, i have artefacts and freeze. If I set 2GB like actually, the guest works perfectly.
>> So i don't know if it will be good for gaming even if i set Windows swap to 10GB ...

>>> Put the 960 into the one that goes 4x if you're that worried about it, but it shouldn't be a huge deal. I don't know if the 960 can even saturate a 4x. It might be able to, but since it's a lower performance card anyway, it shouldn't really matter.
