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. _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
