I recently used Linux in VMware, but I discovered that kvm can replace it, so I created the kvm environment and then started a window on the host system. But when I use it, I have a problem. My guest's performance is not very good. For example, when I use Windows without kvm, the “lol” fps is 160, but my guest is only 135. why? I only have one guest what is the reason? What can we do to promote my performance? There are my some settings for me. timer: hypervclock cpu: 8 socket(intel@ core i7 7700k) memory: 16G GPU: 1060 network: virtio my environment: libvirt: 4.2 qemu: 2.12 windows: windows 7 host: ubuntu server 1604 If you need my detailed settings, please let me know.
Have you tried installing lib-virt drivers for Windows guest ? https://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers Regards, Prasad On 20 May 2018 at 21:10, Allence <15700157322@163.com> wrote:> I recently used Linux in VMware, but I discovered that kvm can replace it, > so I created the kvm environment and then started a window on the host > system. > But when I use it, I have a problem.

My guest was started by a diskless drive. In my window, I can discover that my network is virtio. Is lib-virt drivee like this?
