[Spice-devel] Remote control delay when I access to windows7 kvm virtual machine with spice

[John Y.]

spice-server is 0.12.4-20

I did not add the spice agent.
Can spice agent provide better VGA performance?
I though it just provide data transferring.

I had install spice guest tools.

Regards,
John
