平台是 Debian+Libvirt+virt-manager
内核版本较旧，不支持 VirtIO GPU ，只能用 QXL 。
但就算在虚拟机中使用 QXL 虚拟显卡并为虚拟机安装 SPICE 驱动，虚拟机的图形性能依旧很差，图形加速完全不可用。
网上说 KVM+SPICE 图形性能好，还能玩点页游，但为什么到我这儿就不行呢？

页游也用 gpu ？页游不都是 CPU 渲染而已么………
你可以试试 PCI passthrough 直接挂显卡进去

VGA Passthrough 对硬件有要求

@mingumo 头晕了，信息量好大，不过我已经明白内核如何配置了。

@ryd994 上面说的页游应该是 flash 游戏.最低都是像弹弹堂那种,是要 gps 的.

就算有 VirtIO GPU ，也不支持 windows 客户机吧，用处不是特别大。
