windows-7 – 使用libvirt管理的kvm 64主机上win7 64 guest的最佳设置

我正在使用libvirt来控制运行Debian Squeeze amd64的一个相当新的(核心i3)主机上的kvm.
主机以及 Linux客户端工作并感觉快速且响应迅速.
简单地为Windows7安装带有virt-manager标准配置文件的Win7需要永远.我主要责怪磁盘io,但Windows通常不像linux客户那样响应.

关于kvm上Win7客人的性能优化设置,您有什么提示吗？

(很抱歉有很多转储,但我认为它们很适合作为参考点.)

主机配置：

kvm: Version: 1:0.12.5+dfsg-5+squeeze8
libvirt-bin: Version: 0.8.3-5+squeeze2
