I’m testing Whonix 13 on both VirtualBox and KVM on the same virtualization-enabled machine. On the KVM install I notice a slight, but definite lag in video performance on the basic Workstation interface (no extra apps running). Is tweaking the vram and/or vgamem advisable? If so, can anyone suggestion a rule of thumb for both selecting an optimal value and editing the default configurations? In other words, how much memory should I allocate and what is the best means by which to configure it (virsh -c qemu:///system edit … )?
The following link is perhaps the most insightful piece I’ve read so far … any thoughts or recommendations?
